Null passed pointer reference stub

I use IIS Express. I can't find a solution to this anywhere. I tried clearing out temp files, change the port number from to something else, deleting iis express config files, etc. I even uninstalled and re installed VS Any clues? Obviously something isn't right here, but I don't need Silverlight debugging anyway.

I had this problem and it was caused by IE not being the default browser. You can correct this by following this answer. Visual Studio opens the default browser instead of Internet Explorer. I created a new Silverlight project in VS express edition, C and got nearly the same error upon trying to run the application in debug mode by pressing F5.

The error message also ended with 'A null reference pointer was passed to the stub. I set my default browser to IE10 and now the debug mode for Silverlight applications in C in VS express edition works fine. When I finally got it compiled after a day's slog and no it's not backwards compatible, this is a 1-way upgrade , it ran, but behaved slightly differently.

So I put in some breakpoints which it proceeded to completely ignore. The Silverlight debugger needs to be checked but wasn't. I assumed it was part of the vbproj file?

Instance of interface cannot be created. What to do about it? The first thing I would do with any MS product is uninstall WMP , reboot, reinstall, reboot, test, confirm that the problem still exists, and if so, send appropriate flame to bill.

StumpedTechy said:. I saw one indication that reinstalling WMP10 fixes the problem you may ant to try that - This here was given as a way to install it "over the top".
