visual studio - How to set a breakpoint on a method within the .net framework

Question

I wish to set a breakpoint on the System.Threading.SynchronizationContext::SetSynchronizationContext static method so I can find out when the synchronization context is being set.

However I can’t find how to set a breakpoint in a method I don’t have the source code to.

(This should be easy!, but when I try to set the breakpoint on a method from the breakpoints window it does recognise the method.)

Answer 1

Click Debug, Windows, Breakpoints, click New, Break at function, enter System.Threading.SynchronizationContext.SetSynchronizationContext, and click OK.

It will give you a warning, which you should ignore. I tried it, and it does work.

I also had to turn off the "Enable Just My Code" setting in the Debugging configuration.

Start Visual Studio 2008 and bring up Tools > Options > Debugging > General. If you are running under the Visual Basic Profile, you will need to check the box on the lower left of the Options Dialog marked "Show All Settings" before continuing (other profiles won't have this option). Set the following settings: Turn OFF the "Enable Just My Code" setting
