When you launch your assembly using the Visual Studio Debugger and the Windows Defender service is running, it takes several minutes to launch. If you kill the defender process, the startup is reduced to seconds. Of course this depends on the size of your project, but never-the-less performance of the debugger is hampered by the Windows Defender service.

Details (expand)

Visual Studio 2012

1) make sure the Windows Defender Service is running
2) Open a project in Visual Studio
3) Begin debugging that project (press F5)
4) Wait

In a moderately sized project the wait time for the the application to launch is 5-15 minutes.

With the defender service stopped, the same project launches in < 30 seconds.

It would appear the problem is becoming more severe. The whole build process is now slower when Windows Defender is running. I have to shut down defender to build in a reasonable amount of time.
