I had the same error for weeks

My Problem:

Using C# .NET a web based project was debugging really slow, each step took
about 5 seconds to perform, on another PC my colleague had same project and
was running well in debug. It runs absolutely fine when running without
breakpoints.

Sound familiar?

i have been all over the place trying to find an answer to no avail... so i
decided to find the solution myself and i have fixed it on my PC.

People have told you to close down your Watch windows, remember to delete
old watches. However i stumbled upon the breakpoints window..

Debug -> Windows -> Breakpoints

I had loads in there, so i removed them all by clicking

Debug -> Clear All Breakpoints

Closed the Breakpoints window
I also closed all the watch windows, Sourcesafe Pending checkins window and
the auto and local watch windows Put a new breakpoint in to test it and hey
presto my deubgger is back to its fast paced self. I couldnt believe it.


I now that i think about it in Watch 1 i had a variable that i was watching
a while back i also deleted that. So it could be any of the things i
mentioned causing your project debugger to be slow. Try them and see.

Hope this helps
