Sign a non strong named assembly

April 19, 2011 ASP.NET C# Troubleshooting

If your assembly is signed by strong name key file you will have problems calling non strong named assemblies. You can bypass this with reflection, but it adds a couple of other issues.

There's another possibility. And that is to sign a non strong named assembly using MSIL.

Here are the steps:

1. Obtain MSIL of the given non signed assembly:
C:\ildasm NonSigned.dll /OUT:MyAsm.il
2. Rename the original assebmly to prevent it from getting overwritten.

3. Rebuild the assembly from IL.
C:\ILASM MyAsm.il /DLL /KEY:MyStrongKey.snk
