SharePoint 2013. Where is my DLL? Not registered in Assembly folder

.NET 4.0 has a new gac location

Today, I wanted to quickly update a dll from a custom SharePoint solution. I was puzzled when I could not find the dll in the assembly ( “c:\windows\assembly ” ) folder.

Turns out that starting from .NET 4.0 and up there is a new ‘GAC’ folder in town. It is now situated in “c:\windows\microsoft.net\assembly“. You can simply browse to that directory with Windows Explorer and view all the folders.  The new GAC folder does not hide version information (=folders) anymore like the old one did.

They introduced this new folder 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.

So keep in mind there are two folder now. One for .NET versions 2.0, 3.0, 3.5 and one for .NET versions 4.0 and up.
