Debugging Invoked function in .NET

Question

I call function in .NET using Reflection (Method.Invoke). If an error occurs inside this method and exception is raised, debugger doesn't show actual code but stops at Invoke() call. I can retrieve exception information from InnerException but this is very inconvenient, compared to regular debugging with callstack available and so on. Can methods invoked using Method.Invoke be debugged like regular function calls?

Answer 1

What you're liking hitting is the "Just My Code" feature. The debugger by default limits debugging to code which is deemed authored by the developer. This reduces a lot of noise that would be present in say debugging a WPF or WinForms launch.

In order to have items like the Exception assistant run for all code you should disable Just My Code.

• Tools -> Options
• Debugger
• Uncheck "Enable Just My Code Debugging"

Answer 2

If all else fails, you can also put something like this into the method that gets invoked:

#if DEBUG
    System.Diagnostics.Debugger.Break();
#endif

That will basically "programatically" cause a breakpoint there.

You could also make it slightly better by doing:

  if(Debugger.IsAttached)
    Debugger.Break();

So that it will only break if you are actually running it in the debugger.

Edit:

On 2nd thought, if you have the code to edit it, then you can probably just stick a regular breakpoint there through VisualStudio. I guess my answer doesn't make sense... sorry :)
