Web Projects
1. Much safer to create a new project and delete the old than it is to rename it.
2. If Visual Studio won’t do the checkin, see if the change list can be submitted manually from p4win.
3. Don’t forget to delete web projects in Intenet Information Systems manager after removing them from a project & from perforce.
4. If a Web Application or Web Service project won’t load into Visual Studio, it may need to have its Directory properly configured in IIS. Check that Server Extensions are installed and Properties->directory->Application Settings->Create.
