Answer 1

Using Command line, use the following steps:

Open Visual Studio Command Prompt

First open Visual Studio Command Prompt (For Visual Studio 2008 the path is Programs --> Visual Studio 2008 --> Visual Studio Tools --> Visual Studio 2008 Command Prompt ) All the files mentioned in the following steps will be created in the Visual Studio 2008 Command Prompt Path. In my case it is C:\Program Files\Microsoft Visual Studio 9.0\VC

1. Generate a KeyFile sn -k keyPair.snk
2. Get the MSIL for the assembly ildasm SomeAssembly.dll /out:SomeAssembly.il
3. Rename the original assembly, just in case ren SomeAssembly.dll SomeAssembly.dll.orig
4. Build a new assembly from the MSIL output and your KeyFile ilasm SomeAssembly.il /dll /key=keyPair.snk
5. Install the DLL in to the GAC gacutil -i SomeAssembly.dll
