NetPad

A cross-platform C# editor and playground.

Get Started

NetPad is a C# playground that lets you run C# code instantly, without the hassle of creating and managing projects. Open NetPad, start coding, hit Run, and see your output immediately. It's that simple.

• Prototyping and Testing: Quickly prototype and test code snippets before incorporating them into your projects.
• Data Visualization: Visualize data interactively for better insights and analysis.
• Database Queries: Query databases using LINQ or SQL effortlessly.
• Learn and Experiment: Experiment with new C# features or start learning C# in an intuitive and accessible environment.
• Utility Scripts: Create and save your own utility or administration scripts for repeated use.

Motivation

We love LINQPad, but we miss its tremendous utility when working on non-Windows platforms. This project aims to create an open-source, web-enabled, cross-platform alternative.

The goal isn't to reach 100% feature parity with LINQPad, but to offer an effective alternative that covers features most commonly used and to introduce a few new useful ones.

Requirements

The following must be installed to use NetPad:

• .NET SDK (v6 or greater)

Additional requirements only if you plan to create and use database connections:

• .NET 6 Runtime (not needed if .NET 6 SDK is installed)
• EF Core tools (.NET 5 or later)

Download

Download the latest version for free!

For folks on Arch Linux or Manjaro, you can also install it from the AUR.

On macOS see this if you have trouble opening NetPad.

Updates

NetPad automatically checks for updates each time you start the application and will notify you when a new version is available.

Currently, automatic updates are not supported, but this feature will be added to make updating as seamless as possible. Stay tuned for future updates!

The latest version can be downloaded from the Releases page.

How it works

NetPad runs an ASP.NET web app that hosts a web-based user interface. It can be packaged as an Electron desktop app or served and accessed on any browser.

Communication between the user interface and the ASP.NET backend occurs via HTTP and SignalR.

Build

This section describes how to build and run NetPad from source. NetPad can be run as an Electron desktop app or as a web application accessed with a web browser.

Requirements

• Node v16+ (npm v8+)
• .NET SDK 7.x
• EF Core tools 5.x or later

NetPad as an Electron desktop app

1. Run the SPA

# Install dependencies
cd src/Apps/NetPad.Apps.App/ElectronHostHook
npm install

cd ../App
npm install

# Start the development web server
npm start

2. Run the .NET app

Install the Electron.NET CLI tool:

dotnet tool install ElectronNET.CLI -g

Start the app:

cd src/Apps/NetPad.Apps.App

# Start in watch mode (remove '/watch' to run without watch mode)
electronize start /watch /manifest electron.manifest.dev.js

# For macOS ARM, append the following to the 'electronize start' command
/target custom "osx-arm64;mac" /electron-arch arm64

Note

Only the very first electronize start is slow. Later runs are much faster.

NetPad as a Web app (accessed from a browser)

1. Run the SPA

# Install dependencies
cd Apps/NetPad.Apps.App/App
npm install

# Start the development web server
npm run start-web

2. Run the .NET app

cd Apps/NetPad.Apps.App
dotnet watch run --environment Development

and access the app via your web browser, ex: http://localhost:57930

Packaging 📦

The Electron app is built and packaged using electron-builder. Configuration is in the electron.manifest.js file.

Build the app for the desired platform from the root directory of the NetPad.Apps.App project:

# For x64:
electronize build /target win /manifest electron.manifest.js /PublishSingleFile false
electronize build /target osx /manifest electron.manifest.js /PublishSingleFile false
electronize build /target linux /manifest electron.manifest.js /PublishSingleFile false

# For macOS ARM:
electronize build /target custom "osx-arm64;mac" /electron-arch arm64 /manifest electron.manifest.js /PublishSingleFile false

Packaged files can be found in the bin/Desktop folder.

Notes

1. To build flatpak files the flatpak and flatpak-builder packages need to be installed.
2. On Linux, the /scripts/package-electron.sh script can be used > to package the Electron app, in which case packaged files can be found in > the /dist/ folder.

See the Electron.NET docs for additional CLI options when packaging the app, and electron-builder for additional configuration options.

netpad's Issues

[Mac] "File" menu options disappear after accessing settings window

After opening and closing the settings window, the File menu is (empty).

Also shows (empty) on the settings menu, so I assume what's happening is the app is not switching back to the main window's File menu list.

Is there a way to output raw html to the output window for formatting?

I've tried various things such as:

new RawScriptOutput("<i>asdf</i>").Dump();
new HtmlScriptOutput("<i>asdf</i>").Dump();

But these introspect the object and render as if they were arbitrary objects. I guess this isn't the intended usage.

Looking for something similar to RawHtml() in LP.

Dump not working inside Main Method

I'm Using Netpad 0.4.2 on MacOS

Output from Console.WriteLine works

but Dump is not working

class Tech
{
    public int Id { get; set; }
    public string Name { get; set; }
}

class Startup
{
    public static void Main()
    {
        var t = new Tech
        {
            Id = 1,
            Name = "Test Name"
        };

        Console.WriteLine("Output");
        t.Dump();
    }
}

macOS Zip being produced has a damaged `.app` file

I've downloaded the latest 2 arm-64 zip files. When I unzip them and try to run them. macOS (latest Sonoma) says that the app file is damaged and recommends I trash the file.

Any chance of getting pre-built binaries?

Could we get some pre-built binaries? Even if they are artifacts of the github action that would be ok. I can't seem to get the project to build locally.

error during scaffolding

I just installed netpad version 0.4 on macos, and then installed the .NET7 SDK and later tried installing the 6 as well. In both cases though it fails to scaffold against my postgresql database with the error:

uncaught exception on startup - non-standard network interfaces

I just installed the software for the first time. I am using Windows 11. At startup the software is immediately dying with an EACCES exception that appears to be failure to set up a listener.

See image...

I got to wondering. I run into issues with my own code unless I isolate and use REAL network interfaces. I have VMWare Workstation and Virtual Box installed. Their virtual interfaces for host-only networks cause issues. So I disabled them. Didn't fix it. Then I also disabled the Bluetooth network. The software started right up.

Just letting you know.

[Resolved] Netpad doesn't open on Mac ARM

I'm trying to run the recent version supporting mac arm but it stuck while opening. Even it doesn't quit when right click and press quit. I need to use force quit.

short fix include homebrew bin and sbin in PATH:
Environment.SetEnvironmentVariable("PATH", $"/opt/homebrew/bin:/opt/homebrew/sbin:{Environment.GetEnvironmentVariable("PATH")}");

Maybe add option to Settings to add Homebrew or Azure Cli folder path

Netpad equivalent of "SubmitChanges()"?

Hi @tareqimbasher !

I am so happy I stumbled across NetPad recently. Since moving to Linux, I've dearly missed LINQPad, and your re-implementation makes me feel less homesick :)

I have a dumb question -- what is the equivalent of the global SubmitChanges() in NetPad? How do I save changes after I've made modifications to an entity? There doesn't seem to be a global DbContext instance that I can access.

Thanks again for making this amazing software!

macOS Window Conventions

On macOS, the close, minimise, and maximise buttons appear on the left side of a window's title bar, and menu items appear within the system menu bar rather than within the application's window. It'd be great if NetPad could be made to feel more at-home on macOS by following these conventions.

Image: NetPad above and VS Code below

Thanks for making this though, it's a very useful utility :)

Seeing duplicate values in intellisense results

Hey! Just updated to the latest release! Really amazing work you are doing :)

Just wanted to let you know, I am seeing duplicates in my intellisense:

Netpad 0.4.1 for Mac M2 is broken

when I unzip the file and run the app, I get this error:

Workaround

Until this is fixed, a workaround is to run with the --no-sandbox option. ie:

netpad --no-sandbox

or you can modify /usr/share/applications/netpad.desktop and add --no-sandbox to Exec like this:

[Desktop Entry]
Name=NetPad
Exec=/opt/NetPad/netpad --no-sandbox %U

Other useful information can be found in the linked issues above.

Note

If you ran NetPad and it crashed because of this, the app might still be running in the background. Kill the app process(es) using your task manager before attempting to run it again.

Create subfolders in NetPad to put every connection in it's own environment

When creating a new connection in NetPad, you can choose a subfolder to put it in, so you can create a subfolder for each environment/domain.

The subfolder should have an option to be renamed.
The connection should also have an option to be moved or dragged from/to subfolders.

SqlClient PlatformNotSupported_DataSqlClient

Very excited about this app! Went ahead and installed it on my x86 mac running macOS 13.4.1 with dotnet version 6.0.301 and efcore tools 7.0.9. I'm able to connect to my local Sql Server running in a docker container and can view the db schema in the left hand pane. When I try to run a LINQ query against that database I get the following error. Have I not configured things correctly somehow?

Where is the Sponsor button?

You made a great job and I'd like to sponsor it, you are my hero! XD

Calling Dump with a title, and then dump without, adds more stuff to the titled region

This example:

10.Dump();
20.Dump();

produces this output:

10
20

However, this example:

10.Dump("Title");
20.Dump();

produces this:

| Title
| 1020

I feel like the expected output should be something like this:

| Title
| 10
20

Tested in NetPad 0.6.0 on Windows.

Any interest to do a JavascriptPad?

Feature request: Reuse nuget.config nuget sources for package discovery

We publish nuget packages on Github, in our private organization. It would be nice if the nuget source I have added to my nuget.config file is honored, so that I can use packages we've made, without having to browse for and refer to the base assemblies locally.

Ctrl+R throws error

Hey there! I am so used to pressing ctrl+r to show/hide the results window in LINQPad, I accidently keep calling it in NetPad (I know it is the reload shortcut). Everytime I press it, I get the following error:

Any chance we can get ctrl+r to show/hide the results instead of reloading the browser window?

Thanks! :)

Support for .NET 8 and C# 12

With the recent release of .NET 8 with C# 12, it would be nice if NetPad supported this.

[Mac] Pop-up menu order inconsistent with Mac design language

Please see the below images (one from VS Code, one from NetPad). Generally on Mac the "confirm" and "deny" are grouped, with "cancel" separate.

Database Connections

Allow users to add database connections. As a start, we'll support the following database providers. More providers to be added soon after:

• Microsoft SQL Server
• PostgreSQL

We want to have the following features available at a minimum:

• 1. Add, edit, remove and test a database connection
• 2. Use a database connection in a query and be able to run all common EF Core actions (inserts, delete, selects...etc)
• 3. Show generated T-SQL in a SQL tab in output console
• 4. Protect connection passwords so they aren't persisted in an unprotected format
• 5. Add helper queries to a context menu the user can chose from when right-clicking a connection in the sidebar
• 6. Allow user to override the OnConfiguring method of the generated DatabaseContext in a script
• 7. OmniSharp integration

It can no be installed on MacOS 13.4.1

Hi, I try to run it on my MacOS m1, but it seems not be satisfied.

I tried to redownload it and other versions, but it always shows the same result.

Cannot open: "“NetPad.app” is damaged and can’t be opened. You should move it to the Bin."

Trying to open NetPad.app I receive the following error:
“NetPad.app” is damaged and can’t be opened. You should move it to the Bin.

This happens on MacBook Air M2. Dotnet SDK 7.0.403 is installed.

Help!! NetPad fails to launch on my Mac

Machine: MacBook Pro
Chip: Apple M2 Max
Memory: 96GB

I have downloaded the latest version of the zip on my Mac (M2).

After unzipping and clicking on the app I get the following dialog!!

I've tried downloading multiple times in case the zip was corrupted, but get the same dialog.

I have the following .NET SDKs installed

Please advise

Unable to find dotnet on Linux

Hey,
I am trying to install NetPad on my linux machine (I am still relatively new to Linux) and i basically have the same problem as described in this issue #42.
I think that everything should be configured correctly (I can run "dotnet" and "dotnet ef" without any problems)

When i open NetPad I get missing dependencies popup and it tries to run the "dotnet" and "dotnet ef" command in my browser:

The dotnet-ef tool is not functioning properly on NetPad on macOS.

I've already set up the .NET SDK and installed the dotnet-ef tool. It runs fine in the local command line. However, on the App Dependencies Check page, it shows that the .NET SDK is installed successfully, but dotnet-ef displays "Entity Framework Core .NET tool is not installed."

Can't stop a runaway query without killing the app

I'm unable to stop a runaway query without closing NetPad. It seems to only happen when logging to the console or using .Dump().

Minimal Repro

while (true) {
    Console.WriteLine(DateTime.Now);
}

PostgreSQL columns with custom enum types are not being derived.

The columns which have enum type in Postgres like
CREATE TYPE t1 as ENUM ('V1', 'V2')
do not appear in the generated schemas.

.Dump() causes stack overflow when dumping objects that have long or infinite property chains

Accidentally stumbled on this trying to .Dump() a bad DirectoryInfo:

new DirectoryInfo("boguspath").Dump();  // On Mac if that makes a difference

Similar results can be seen with this arbitrary example.

new Foo().Dump();

public class Foo
{
    public Foo Parent { get { return new Foo(); } }
}

Reference tracking isn't properly catching these cases, and there doesn't appear to be anything limiting .Dump() depth. Output window shows stack overflow with really long stack trace first time but eventually the application hangs. Similar applications has a setting for max depth (default in settings or argument to Dump()).

Example output:
Stack overflow.-------------------------------- at NetPad.Html.HtmlSerializer.Serialize(System.Object, System.String) at O2Html.HtmlConvert.Serialize[[System.__Canon, System.Private.CoreLib, Version=7.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]](System.__Canon, O2Html.HtmlSerializerSettings)-------------------------------- at ExternalProcessOutputWriter+<WriteAsync>d__4.MoveNext() at O2Html.HtmlSerializer.Serialize[[System.__Canon, System.Private.CoreLib, Version=7.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]](System.__Canon, System.Type, O2Html.SerializationScope) at ScriptRuntimeServices.ResultWrite(System.Object, System.String) at System.Runtime.CompilerServices.AsyncMethodBuilderCore.Start[[System.__Canon, System.Private.CoreLib, Version=7.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]](System.__Canon ByRef) at Extensions.Dump[[System.__Canon, System.Private.CoreLib, Version=7.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]](System.__Canon, System.String) at ExternalProcessOutputWriter.WriteAsync(System.Object, System.String)Repeat 10235 times: at O2Html.Converters.ObjectHtmlConverter.WriteHtml[[System.__Canon, System.Private.CoreLib, Version=7.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]](System.__Canon, System.Type, O2Html.SerializationScope, O2Html.HtmlSerializer) at Program.<Main>$(System.String[])

Latest release seems broken

Hi,

I'm new to this project, so please forgive my ignorance.

I've download NetPad for Mac (both versions). The ARM version refused to start ("This app is damaged and cannot be opened").

The x64 version does run but fails on the most basic operation (see screenshot below)

I don't have a lot of other info to share at this moment, just wanted to raise the issue I encountered trying out the project. I have every major .NET SDK installed on this machine.

Login into a server/ grouping

Any plans to allow login into a server, rather than just a specific DB?
Then just perform the scaffolding when a database within it is selected?

We have a lot of databases, so it's quiet time consuming setting up a new connection for each one.
Also gets quite messy with all the tests and prod database together without the ability sort things in folders.

Azure data studio does a pretty good job at it -

Allow running unsafe code

Discussed in #95

^{Originally posted by carlos-truong October 3, 2023}
When I run unsafe code in NetPad, I receive this error:
[Error] Unsafe code may only appear if compiling with /unsafe

Is there any way to allow unsafe code in NetPad?

[Mac] "Meta" / Cmd key not working for keyboard shortcuts

I've tried with Ctrl+Enter on Mac and it works properly. Appears to be a Meta/Cmd button issue.

Based on the below, I think the proper way to handle it in Mac would be to give "Run" (and other commands) proper menu bar support and then map them that way, rather than mapping them in the browser window, which seems to be a shortcoming in mac that doesn't allow Cmd to be registered as a browser window listener.

Add (Close Other Tabs - Close All Tabs) shortcuts

Native support?

Does it support natively Silicon chips? It seems there is on x64 version for macs.

Add Blazor support

Would it be possible to support Blazor, so that we can test Blazor pages or components ?
Thank's

Scaffolding postgre database failed: Could not compile data connection assembly

Hello,

It seems that NP cannot compile my database: Postgre 14
If I open my postgre database in LinkPad it works (windows), if I do the same in NetPad (macos) it can't. I also tested my connection and it succeeded. Not sure what I'm missing, maybe this part is failing :

NetPad/src/Infrastructure/NetPad.Infrastructure/Data/EntityFrameworkCore/EntityFrameworkResourcesGenerator.cs

Line 231 in 5be4889

var dbContextPropertyName = $"{propertyName}_HIDDEN";

[Mac] Window size is not saved, always opens full-screen

Here is an issue in the Electron project with recent fixes:

electron/electron#526 (comment)

[Mac] Mac Design Patterns

Some menu item locations are incorrect based on Mac design patterns, as well as default shortcuts.

For example, "Settings" should always be in the named dropdown (ex. "NetPad") and should always have the default shortcut of "Cmd + ," (⌘ ,). This may require registering the Settings (called Preferences until 2 versions ago) in a special way, I'm not sure.

Pop-up choice order should be updated:

Please see the below images (one from VS Code, one from NetPad). Generally on Mac the "confirm" and "deny" are grouped, with "cancel" separate.
