How to find which methods/functions of a Project is used in another Project is VS 2012?

Question

I have a solution which has two projects Project1 and Project2. Project1 refers to Project2. Project2 has a number of methods/functions that is used across different classes inside Project1. How can find out all the methods/functions of Project2 that are used in Project1?. I am using Visual Studio 2012.

I am using .NET framework 4.0 and C#

I have already read the thread the following thread, which is related to an assembly (possibily without source code) https://stackoverflow.com/questions/25606360/how-to-find-out-wich-methods-from-an-assembly-are-being-used-in-another-assembly

Edit

The answers suggest that I use tools like ReSharper and NDpend. These are not free tools, even though it might meet my need. I do not want to spend big money for such a small feature.

Answer 1

NDepend is a great tool for tasks like this. It e.g. provides a dependency matrix which you can expand/collapse:

Answer 2

Remove reference to Project2 from Project1. Then go through the error list and you'll get the methods.

EDIT: you can use Resharper, which can find all usages of project (and of a class, a method ...)

Answer 3

Right-click on solution, choose Project Dependencies, choose the first project in the Projects drop down list, and scroll over projects.

It's easier using Resharper:

Right-click on module and choose Project Hierarchy, then click Referencing projects to see all project references

Answer 4

There's a extremely simple solution for this: remove the reference of Project2 on Project1 and build Project1. You'll instantly get all classes that aren't present in Project1 but in Project2 as build errors.
