How to check if assembly exists and get assembly info in Profiler?

Hi,

I use IMetaDataAssemblyEmit::DefineAssemblyRef method to define my probe reference.

If I set the parameter ASSEMBLYMETADATA'sversion is 1.0.0, but the probe in GAC is 1.1.0, the w3wp.exe crash.

So I think I shouldverify the probe first.

When PublicKeyand szName is fixed, how to check whether the assembly exists or not, and get its information like version?
