We are using VS 2010 with TFS and have a few WCF projects. We also use TFS's Branching feature. The WCF projects are set up to use the Local IIS Web server. Each site has a custom Application Pool.
When I open a branch solution, I receive a dialog that says something like
"The Web project 'TestService' is currently configured to use the URL 'http://localhost/TestService". The Web server has this URL mapped to a different folder. Would you like to remap this URL to point to this Web project's folder?"
If I say Yes to this dialog, it changes the physical path but it also changes the Application Pool to the ASP.NET v4.0 pool instead of the custom pool that is set up, but I do not know what is causing this behavior.
