SYMPTOMS
The CPU usage may increase unexpectedly to 100 percent when you create a Console Application or a Windows Forms Application in Microsoft Visual Studio .NET.

This problem may occur when the Console Application or the Windows Form Application creates an application pool and starts another program inside the application pool. The CPU usage increases even though the program in the application pool is not being used.
