Win Service project won't Build after switching to Any CPU config

Question

I\'m trying to find a fix for my problem. After changing my .net 4.0 C# Win Service project to Any CPU/Release build configuration, I am getting this compile time error:

Answer 1

This fix worked for me by toggling the Output Type. Do not know why, but seems to clear the CS2017 error. Then build works. No changes to code were made.

1. Project > Application > Output type: Class Library
2. Build - good build, but does not run
3. Project > Application > Output type: Console Application
4. Build - good build, code runs

Answer 2

Fixed! I'll include the solution in case anyone else comes across this strange build behavior. I found a forum thread on MSDN that had the solution to the problem. In the project file I removed the value between the <StartupObject> tags and left it blank. Now builds successfully without the previous error.
