Compile Time: How can I check if a datatype (and or value) is being used within a method

Question

At compile time, how can I check if a data type (and or value) is being used within a method.

I'm attempting to build a living architecture that supports plugins.

I want the compiler to throw an error if an event is not being raised within the plugin.

I'm using VS2015 Preview.

Any suggestions?

This kind of validation is possible to implement using PostSharp. It is not trivial but easier than using Mono.Cecil. SyntaxTreeVisitor and ISyntaxReflectionService is a good foundation for implementing the analysis algorithm which has to be invoked from Aspect.CompileTimeValidate.

Roslyn must be mentioned as well. It allows you to "extend" C# (or VisualBasic) compiler with custom diagnostics and it is very well integrated with VS2015.
