WmiLight

What is WmiLight?

A simple and light wmi framework. It has only one function: sending WMI queries. It's a subset of the System.Management.Instrumentation namespace.

In which case should you use WmiLight?

The .Net framework implementation has one big problem. It leaks a little bit memory on each remote operation. Use this framework if your application is a service or runs a long time and you're sending a lot of remote queries.

Installation

This project is being distributed as a NuGet package, so open your Package Manager Console window and execute the following command:

How to use?

Query all running processes for the local machine:

using (WmiConnection con = new WmiConnection())
{
    foreach (WmiObject process in con.CreateQuery("SELECT * FROM Win32_Process"))
    {
        Console.WriteLine(process["Name"]);
    }
}

Query all partitions for a remote machine:

var opt = new WmiConnectionOptions() { EnablePackageEncryption = true };
var cred = new NetworkCredential("USERNAME", "PASSWORD", "DOMAIN");

using (WmiConnection con = new WmiConnection(@"\\MACHINENAME\root\cimv2", cred, opt))
{
    foreach (WmiObject partition in con.CreateQuery("SELECT * FROM Win32_DiskPartition"))
    {
        Console.WriteLine(partition["Name"]);
    }
}

Other benefits:

• easy usage

• no distinction between local and remote queries

• Debugger Preview
