How to modify code before compilation?

Question

Using Roslyn, I would like to modify my C# code before the actual compilation. For now, I will just need something like:

[MyAnotatedMethod]
public void MyMethod(         


        

Answer 1

It is a little more dirty than using an Annotation, but blocking code out using Preprocessor Directives will allow you to configure how your code compiles based on flags.

Code in the #ifMyFlag in the below will only be compiled if MyFlag is defined

#define MyFlag
public void MyMethod() 
{
    #if MyFlag
        // Flag conditional code

    #endif

    // method-body 
}
