What is the value of the ProjectTypeGuids tag in the visual studio project file

Question

What is the meaning of the ProjectTypeGuids tag in a visual studio project? When I created the WPF application, I see two GUIDs here.

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

Do they mean WPF and Windows application types?

If I create my own project type (.myproj) with .xaml and .cs files, what should I fill in with these ProjectTypeGuids tags? Should I also populate the ProjectType tag?

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

Answer 1

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

So your ProjectTypeGuids is for a WPF C # project.

In the register, you can see the value of another GUID:

• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\10.0\Projects for ProjectTypeGuids
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\10.0\Packages for link to packages for the project

From MZ-Tools: List of Famous Project Types Guides :

Each Visual Studio project has a project type (Windows project, Smart Device project, website project, etc.), and in some cases more than one type (subtypes or tastes).

Each project type is identified using a unique Guid, so each project has one or more types of project types.

Project Type Guides are usually stored in the project file:

 <PropertyGroup> <ProjectTypeGuids>{A860303F-1F3F-4691-B57E-529FC101A107};{F184B08F-C81C-45F6-A57F-5ABD9991F28F}</ProjectTypeGuids> ... </PropertyGroup> 

But for some special projects (for example, some database projects) and projects that do not have a file (for example, website projects), the project type is also saved in the solution file:

 Microsoft Visual Studio Solution File, Format Version 10.00 # Visual Studio 2008 Project("{F184B08F-C81C-45F6-A57F-5ABD9991F28F}") = "SqlServerProject1", "SqlServerProject1.vbproj", "{BE5F0BE0-93CD-4FCE-A853-9096A442DF1B}" EndProject 

Project Type Guides are stored in the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\<version>\Projects . However, not all Guides stored in this registry key are actual project types. Some of them are used only to provide project templates (for C # and VB.NET projects), while others are used for other purposes. The following table lists known types of project commands.

The thread in msdn is already running, and much has been discussed there. If anyone is interested in learning about this, check the value of the ProjectTypeGuids tag in the visual studio project file.

ProjectTypeGuids is used by Visual Studio to aggregate projects. For your example, you have WPF (represented by 60dc8134-eba5-43b8-bcc9-bb4bc16c2548 ) C # Project (represented by FAE04EC0-301F-11D3-BF4B-00C04F79EFBC ).

If you have your own type of project that works with both .xaml and .cs, you should try adding your own guid project (specified by your factory GUID project), as shown below:

<ProjectTypeGuids>{YourProjectFactoryClassGUID};{60dc8134-eba5-43b8-bcc9-bb4bc16c2548};{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC} </ProjectTypeGuids>
