.net - What is the significance of ProjectTypeGuids tag in the visual studio project file

Question

What is the significance of the ProjectTypeGuids tag in a visual studio project?? When I created a WPF application, i am seeing two GUIDs in here.

{60dc8134-eba5-43b8-bcc9-bb4bc16c2548};{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}**

Does these represent WPF and Windows type of applications?

If I create my own project type (.myproj) that has .xaml and .cs files, what should I fill in this ProjectTypeGuids tags? Should I also need to fill the ProjectType tag?

It would also be better if someone differentiate the ProjectType and ProjectTypeGuids*tags.

Answer 1

• {FAE04EC0-301F-11D3-BF4B-00C04F79EFBC} is the GUID for C# project
• {60dc8134-eba5-43b8-bcc9-bb4bc16c2548} is for project in WPF flavor package

So your ProjectTypeGuids is for a WPF C# project.

You could see the meaning of the different GUID in the register :

• HKEY_LOCAL_MACHINESOFTWAREMicrosoftVisualStudio10.0Projects for ProjectTypeGuids
• HKEY_LOCAL_MACHINESOFTWAREMicrosoftVisualStudio10.0Packages for packages reference by some project
