Ok. I found why I got a configuration exception every time I launched my azure project (in visual studio 2010).
I have installed Azure Tools 1.4, on my Visual Studio 2010 SP1.
The problem
When I launched the appFabric / Azure Compute Emulator, I got a my visual studio telling my that I he didn’t have any trace or disassembly information.
The most annoying part of this situation is that my WebRole Entry point wasn’t started neither.
This was the error (cut some path’s out to keep it readable).
System.Configuration.ConfigurationErrorsException was unhandled

Solution
So what does it mean. If you open up the config file mentioned in the (inner) exception. You might notice this is not a complete configuration file. For me it was my App.Settings file.
What I did? I moved my app.Settings into my Web.config file. And gone was the error.
I think this is a bug. So, I posted it to Microsoft Connect so you can review it overthere:

Today I looked at the ASP.NET 2.0 Themes. I've been using them for a long time, but I never knew that you can set a default theme in the web.config.
Just add this to the system.web section
<pages styleSheetTheme="Black"/>
Further more I needed to change my theme dynamically. I found an interesting article on this topic on CodeProject.
CodeProject: Dynamic themes in ASP.NET 2.0 (C#).
