PowerShell how to add-type from GAC

I try to call Add-Type -AssemblyName myassembly, and myassembly has been registered into GAC, but I always got following error:

Cannot add type. The assembly 'myassembly' could not be found.

I know how to Add-Type from a file location, is there a way to Add-Type from GAC conveniently?

To load from the GAC you need the fully qualified assembly name:

Add-Type -AssemblyName "Microsoft.Web.Deployment, Version=9.0.0.0", Colture=netural, PublicKeyToken=89956cdc9090cc76"

And yea, it's really annoying!

If you copy it to another computer, you have to unblock it.

You can also use [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.Web.Deployment') Yes I know its obsolete and you should use Load().

Often you may not have the full name and don't care to enumerate the assemblies in the GAC. This will allow you to load the assembly. If you care, you can then pull the fullname to use with Load() for your scripts going forward.

[System.Reflection.Assembly]::LoadWithPartialName('system.web.security')
PS c:\> [System.Web.Security.Membership].Assembly.Fullname
System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
