assemblies - Register multiple versions of same assembly in GAC -

I have to register two versions of the same assembly in GAC.

It is possible to register both versions of what I think, however, when I try to register another one using gacutil.exe, I get the following message:

The assembly already exists in the cache. Use / F option to overwrite

The conference I am trying to register is Microsoft. There are two versions 10.0.1600.22 (SQL Server 2008) and 10.50 for analysis analysis and registration. 1600.1 (SQL Server 2008 R2).

When I look at GAC in Windows Explorer, the "version" column for "DLL" is called "10.0.0.0" rather than the full version number.

> Is there any way to register these two assemblies? No, their assembly versions are similar (which is strange) - the version you are seeing (

Or file version.), GAC only takes into account the assembly version while evaluating the identity. To learn more see the AssemblyVersionAttribute and AssemblyFileVersionAttribute in MSDN / TECHNET
