I have VS 2012 Update 1. My solution contains many projects:
- Two WPF applications
- Several class libraries
- One web application
- An Azure cloud service project, which contains a web role for the web project. This includes the new caching mechanism.

When the solution is started, the Azure project and one of the two WPF applications start. Over time (hours to days), I begin to experience a few symptoms (see actual results).

The exact same app actually running in Azure runs *perfectly*.

I've found that deleting my .suo file is a good short-term fix. The first time I run the app, everything works. The more I start/stop the app and debug, the worse things get. Sometimes restarting the PC helps, but not always. Because deleting the .suo file initially fixes the problem and the app runs file in Azure, I tend to think it isn't an app problem, but rather a Visual Studio problem.

Details (expand)

Visual Studio 2012

Set, remove, etc. breakpoints. Start/stop the app a few times. As time goes on it gets worse.

1) The app can take a long time to start -- multiple minutes. The symbols are slow to load.
2) Sometimes the IIS worker goes and stays at a high CPU level even when the app isn't doing anything.
3) The web portion of the app seems to stop responding to some requests. If you click a link in the browser, the ASP.NET MVC controller runs and completes just fine, but the browser sits there as if it never received a response.
4) Occasionally I'll receive an error message -- not the one saying Azure roles are taking a long time to start, but something related to debugging. I don't recall the actual error, but if I get it again I'll post it here.

- Debugging works correctly
- App starts up in a reasonable time
- All requests sent to the app are properly returned to the client (be it a browser or the WPF app).
