Exception "Unable to load one or more of the requested types"

It works perfectly until I try to include in my query string an enumeration, then I get this exception - **Unable to load one or more of the requested types**
and this in the LoaderException **Could not load type "Microsoft.ApplicationInsights.Extensibility.ISupportConfiguration" from assembly "Microsoft.ApplicationInsights"**

Start by reproducing the request whose query string includes an enumeration, then inspect the full LoaderException for the Microsoft.ApplicationInsights assembly and ISupportConfiguration type. Done means the enum query no longer produces the reported type-loading exception, with the underlying compatibility cause identified.
