Question

I have a Visual Studio 2010 solution that contains multiple projects. One of these projects is a library, which I have added a method to. Within visual studio I can navigate from the method call in my main project to the method in the library, but when I attempt to build/run the solution it gives me a “does not contain a definition for ‘My_Method'”. What am I doing wrong?

Answer 1

It looks as if the library project isnt being rebuilt on each run, assuming that the project reference is correctly added (right click on references -> add reference -> select your library project)

You should make sure that your library is being rebuilt when you run.

To do so :

• Right click on your Solution

• Click on Configuration manager (approximative translation)

• Make sure that the build is checked, if not, check if for the library project
