Probing assembly in .net

Question

I know that how CLRprobing assembly but I want to know:Is CLRprobing assembly in GAC folder?

Answer 1

The CLR will check the GAC prior to using the probing hints. The full details of the order in which assemblies are found are located on MSDN.

Basically, once the CLR knows which assembly (including version) needs to be found, it sees if it's loaded already, then checks the GAC, then probes using the probing hints.
