How do I attach Visual Studio to a process that is not started yet?

Question

I have .NET program that can\'t be run from Visual Studio for some reasons (Excel file created from an Excel 2010 template project) for which I need to debug startup events.

Answer 1

You can start the debugger from your code via

public static void Main(string[] args)
{
  System.Diagnostics.Debugger.Launch();
}

But don't for get to remove this line before shipping your application. Maybe you want to use compiler flags to be sure:

    public static void Main(string[] args)
    {
      #if debug
      System.Diagnostics.Debugger.Launch();
      #endif
    }
