I'm having difficultly calling a static C# method from a custom C# assembly.
I've a small dll comprised of nothing more than:
// Add two numbers
public class AddClass
public static long Add(long i, long j)
return (i + j);
I compile this into Test.dll, and then attempt to load it with:
Add-Type -Path "C:\Users\jdav.IDI\AppData\Local\Temporary Projects\Test\bin\Debug\Test.dll"
This appears to take, as if I run:
I see this among the results:
GAC Version Location
---- ------------- --------------------
False v4.0.30319 C:\Users\jdav.IDI\AppData\Local\Temporary Projects\Test\bin\Debug\Test.dll
However, when I attempt to use the Add method like so:
It errors with:
Unable to find type [AddClass]: make sure that the assembly containing this type is loaded.
At line:1 char:1
+ CategoryInfo : InvalidOperation: (AddClass:TypeName) , RuntimeException
+ FullyQualifiedErrorId : TypeNotFound
I've tried this both from v3 and v2 environments. I figure I'm missing something very fundamental...please enlighten me! Thanks!

You need to either fully qualify the type name, like this][MyMethods.AddClass]]or you need to create a type accelerator for AddClass that maps to MyMethods.AddClass.
See this article for more details about creating type accelerators so that you don't have to fully-qualify the .NET types you work with:

Ah, have definitely heard the phrase "type accelerator" before, but it didn't click till this experiment that that's what I was after.
Thanks a mil Kirk for the reply, your very informative writeup, and all of your other blog tips to date!
