VS2012 Breakpoints are not getting hit

Question

I have a class that looks like this:

public class MyService
{
    private MyService(){}
    public static string GetStuff()
    {
        var stuffDid = new          


        

Answer 1

I had this happen in a 1 project out of 25 which were all in the same solution. The other projects honored breakpoints but this 1 didn't. I removed the project from the solution (delete, not unload) which broke all references to it and then added it back to the solution and that worked!

If that doesn't work you may want to recreate the problem project from scratch and add that new project to the solution.

The best explanation I have for why this worked apart from pure luck is that we migrated projects from one version of VS to another many, many times over the years and maybe one of those migrations caused this problem.
