How to get Assembly full name(VersionNo, Culture, PublickeyToken)

In Visual Studio, Open a project, Debug Menu-->Windows-->Immediate
Shortcut: (Alt + Ctrl + i) or (Ctrl + D, I) open the Immediate Window

?System.Reflection.Assembly.LoadFile(@"C:\Path\YourAssemblyName.dll").FullName

P.S.
If you can't see the immediate window:
I am guessing that you picked a profile that hides this window.
Try: Tools->Import and Export settings->Reset all settings, and pick general development settings.

If you encoutered with following message:
"Design time expression evaluation for class libraries requires the Visual Studio hosting process which is unavailable in this debugging configuration."
Be sure in the project "Enable the Visual Studio hosting process" is checked, enabled.
Be sure in the project "Enable the Visual Studio hosting process" is checked, enabled.

The host process which is pointed to in above message refers to a feature of the CLR, Hosting allows one to configure the CLR before it gets started. One primary use of this is configuring the primary AppDomain and setting up custom security policies. Which is exactly what the hosting process is doing. in debug mode you are running with a customized version of the CLR, one that improves the debugging experience.
