Using breakpoints in visual studio 2010 for BHO in IE

I'm developing a BHO in Visual Studio 2010. So far I've managed to register the BHO and get visual studio launch IE when I hit debug. The BHO works as expected but unfortunately break points that I set are never hit. Is there something that needs to be configu开发者_如何学Gored first?

If you're using .NET 4.0 the debugger won't attach properly to IE. So here is what you do:

Run Visual Studio as an administrator.

Add the following code to your BHO:

Debugger.Break();

Experiment a bit with placement; I'd say set it after the site is set.

Run Internet Explorer independently of Visual Studio. As in don't launch IE from within Visual Studio. When IE runs you will get a crash window (the result of the code above); that's when you can attach Visual Studio to IE. Done and done.

Are you sure you have registered the 'debug' dll and not the release one (that didn't contain debugging information) ?

Personally I created a scrip that register the dll and this script is executed each time I compile (post-processing).

Hope that help !

EDIT:

I'm using VS 2008 but could you check if your configuration correspond to mine ?
