I've got a problem with the ResourceContentManager in XNA 3.0. I'm using a global ResourceContentManager to load frequently used effect and texture assets from a resx file. Using XNA 2.0 everything works fine - since upgrading to XNA 3.0 the loaded assets get lost after 3-5 frame updates and an exception about accessing disposed objects is thrown. There is no call to unload the resource content manager and none of the assets have been manually disposed. The debugger shows that the content manager lost all files that has been loaded. Did I missed some changes to the ResourceContentManager?

Thanks a lot in advance!

Edit: Problem Solved! :) A "Clean Solution" and rebuild did the job!
