I added two assemblies using GACUtil. Both were added successfully however one shows up under C:\Windows\Assembly and the other under C:\Windows\Microsoft\Assembly\GAC_MSIL".

Why would it happen this way when i had used the same command for both assemblies?

Thanks

Manny

    How is this a SharePoint question? – Dave Wise Sep 04 '12 at 20:16
  • Technically it is more of a .NET question. But i am referencing the assemblies inside Sharepoint (v4.master), I figured Ill post it here. –  Sep 04 '12 at 20:31

    You should probably clarify that then as DLLs are never deployed via GACUtil in SharePoint. They are deployed as part of a solution which takes care of issues like this automatically – Dave Wise Sep 04 '12 at 20:33

In .NET Framework 4.0, the GAC went through a few changes. The GAC was split into two, one for each CLR.

The CLR version used for both .NET Framework 2.0 and .NET Framework 3.5 is CLR 2.0. There was no need in the previous two framework releases to split GAC. The problem of breaking older applications in Net Framework 4.0.

To avoid issues between CLR 2.0 and CLR 4.0 , the GAC is now split into private GAC’s for each runtime.The main change is that CLR v2.0 applications now cannot see CLR v4.0 assemblies in the GAC.

.NET 4.0 has a new GAC, why?

hope this answers it for you :)
