I have a PowerShell V2 script that moves some files around and installs some services. However I would like to call and run a .cs file about halfway through the PowerShell Script. I have found plenty of articles on calling PowerShell from C# but none the opposite way around. I would just like the C# file to run once then continue running the PowerShell script.

If anyone could point me in the direction of an article explaining how to accomplish this or if you know yourself and could help it would be greatly appreciated.

[BasicTest]::Add(4, 3)

# Create an instance and call an instance method
$basicTestObject = New-Object BasicTest
$basicTestObject.Multiply(5, 2)
public class BasicTest
    public static int Add(int a, int b)
        return (a + b);
