How can I access the path on disk where an assembly is loaded from when I am looping through a CSharpProjectAssembly.AssemblyReferences collection instance? The IProjectAssemblyReference does not appear to have any location property but when I debug and inspect the running variable I am able to drill down to a property called location that has the file path. What interface do I need to cast the IProjectAssemblyReference instance to inorder to get access to the location property?
