Cannot [System.Type]::GetType of type from assembly System.Configuration

Question

I'm trying to register soap extension programatically in powershell, like it is described here, but I have problem with this one particular method: [System.Type]::GetType("System.Configuration.ConfigurationElementCollection, System.Configuration", $true)

Exception calling "GetType" with "2" argument(s): "Could not load file or assembly 'System.Configuration' or one of its dependencies. The system cannot find the file specified."

This is output from Fusion Log Viewer when running this line directly in powershell.exe:

*** Assembly Binder Log Entry  (9/20/2013 @ 10:42:57 AM) ***

The operation failed.
Bind result: hr = 0x80070002. The system cannot find the file specified.

Of course assembly is present in GAC:

The Global Assembly Cache contains the following assemblies:
  System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL
  System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL

The same problem occurs if I use assembly full name in powershell line above.

Answer 1

You need to specify the assembly-qualified type name, unless the type is in the current assembly or mscorlib.dll. This should work:

[System.Type]::GetType("System.Configuration.ConfigurationElementCollection, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a", $true)
