Options to query and extract code related data from large Visual Studio solutions

I need to extract lots of data information from a large .net solution.

For example:

give me a list of all decimal properties of all classes that implement an specific interface.

At this point I am building custom code to do the job. It is very tedious and needs a re-compile upon any change.

Is there any Query (i.e Linq Query) tool (or technique) that uses Roslyn (or reflection anything lease) and help with extracting meta data that I need without such heavy duty Roslyn coding?
