This repo contains the Template Engine which is used by dotnet new

Overview

This repository is the home for the .NET Core Template Engine. It contains the brains for dotnet new. When dotnet new is invoked, it will call the Template Engine to create the artifacts on disk. Template Engine is a library for manipulating streams, including operations to replace values, include/exclude regions and process if, else if, else and end if style statements.

Template Content Repositories

.NET default templates are located in several repositories. This repository only contains the following templates:

• Console Application (console)
• Class Library (classlib)
• Common item templates (gitignore, globaljson, nugetconfig, sln, etc.)

Other templates are located in the following repositories:

Templates	Repository
ASP.NET and Blazor templates	dotnet/aspnetcore
WPF templates	dotnet/wpf
Windows Forms templates	dotnet/winforms
Test templates	dotnet/test-templates
MAUI templates	dotnet/maui

Issues for the template content should be opened in the corresponding repository.

Template Samples

We have created a dotnet template samples repo, which shows how you can use the Template Engine to create new templates. The samples are setup to be stand alone for specific examples.

Info for dotnet new users

You can create new projects with dotnet new, this section will briefly describe that. For more info take a look at Announcing .NET Core Tools Updates in VS 2017 RC.

To get started let's find out what options we have by executing dotnet new --help. The result is pasted in the block below.

$ dotnet new mvc --help

MVC ASP.NET Web Application (C#)
Author: Microsoft
Options:
  -au|--auth           The type of authentication to use
                           None          - No authentication
                           Individual    - Individual authentication
                       Default: None

  -uld|--use-local-db  Whether or not to use LocalDB instead of SQLite
                       bool - Optional
                       Default: false

  -f|--framework
                           1.0    - Target netcoreapp1.0
                           1.1    - Target netcoreapp1.1
                       Default: 1.0

Let's create a new project named "MyAwesomeProject" in the "src/MyProject" directory. This project should be an ASP.NET MVC project with Individual Auth. To create that template execute dotnet new mvc -n MyAwesomeProject -o src/MyProject -au Individual. Let's try that now, the result is below.

$ dotnet new mvc -n MyAwesomeProject -o src/MyProject -au Individual
The template "MVC Application" created successfully.

The project was successfully created on disk as expected in src/MyProject. From here, we can run normal dotnet commands like dotnet restore and dotnet build.

We have a pretty good help system built in, including template specific help (for example dotnet new mvc --help). If you're not sure the syntax please try that, if you have any difficulties please file a new issue.

Now that we've covered the basics of using dotnew new, lets move on to info for template authors and contributors.

Available templates

You can install additional templates that can be used by dotnet new. See Available templates for dotnet new.

What to expect when working with this repo

The instructions below enable a new command at the dotnet CLI, dotnet new3, that uses the bits and templates contained in this repo. Think of it as a "preview" version of dotnet new for trying out new switches, interactions and display styles before rolling them in to the product.

Commands executed against dotnet new3 won't impact the behavior of dotnet new, Visual Studio for Mac, Visual Studio, nor any other environment.

How to build, run & debug

Check out our contributing page to learn how you can build, run and debug.

Installing templates

Templates can be installed from packages in any NuGet feed, directories on the file system or ZIP type archives (zip, nupkg, vsix, etc.) To install a new template use the command:

dotnet .\dotnet-new3.dll -i {the path to the folder containing the template or *.nupkg file or nuget package name}
dotnet .\dotnet-new3.dll -i "Boxed.Templates::*"
dotnet .\dotnet-new3.dll -i <your repo location>\artifacts\packages\Debug\Shipping\Microsoft.DotNet.Common.ProjectTemplates.3.1.6.0.0-dev.nupkg
