Question

Is there a way to figure out if every function defined in code is called somewhere?

I have been doing a major code update to a large project of mine and I want to make sure the old functions that are no longer used are removed from the code.

Is there a better way then searching for each function in the solution?

Answer 1

Mark each method you are trying to remove as Obsolete with IsError set to true. When you mark a method as such, you will get a compilation error and will be able to find out if you can safely remove the method.

    [Obsolete('Don't use this method', /* IsError */ true)]     public void Foo () {}
