Visual studio very slow debugging, Visual Studio Slows down in debugg mode

These two approaches has solved this problem for me.

1) Delete all break points.

2) Go to tools -> options -> debugger -> symbols and check if you have public symbols set or UNC network paths set. Also check tools->options->debugger->general to see if you have source server set.

These options tries to download some symbols from internet. All of these can affect debugging based on slow network speed or unavailable servers. The 5 minute wait time is network timeouts.

 Hope this helps.
