Is it possible to convert Windows Phone App project into Windows Phone Class Library?

Question

I accidentally created a Windows Phone App project instead of Windows Phone Class Library project and worked on it for few days, till I realized that when I'm running the "end-point" application it installs the "library" as an app as well.

So is it possible to convert Windows Phone App project into Windows Phone Class Library?

Answer 1

Luckily the solution was very easy.
Instead of creating new Windows Phone Class Library project and manually moving files into it,
I modified the Project.csproj:

1) Close Visual Studio
2) Change SilverlightApplication tag to false
3) Remove tags:
SupportedCultures
XapOutputs
GenerateSilverlightManifest
XapFilename
SilverlightManifestTemplate
SilverlightAppEntry
4) Open VS and clean the project

That's it!

P.S.: Tested on WP7.1 & VS2012
