I downloaded a Visual Studio project but I can't open it in my copy of Visual Studio 2010. Useless error message:
The project type is not supported by this installation.
What software do I need to open the project type? It doesn't say.
I actually went and read the .csproj
file, it tells me it's project type
<ProjectTypeGuids>{786C830F-07A1-408B-BD7F-6EE04809D6DB};{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}</ProjectTypeGuids>
Am I meant to recognise what software I need from this random string? This is absolutely ludicrous.
Project Type GUID is a unique key used in registry to identify specific project type. Visual Studio keeps all stuff (editors, projects, menu items, tools, etc. ) in system registry.
Project GUIDs Uniquely Identify Projects Visual Studio uses project GUIDs to identify different project files and their dependencies in a solution file, as well as for references between projects inside a single solution file. For this to work, it needs all project GUIDs to be unique inside a solution file.
Check the project format in Visual Studio If you are working in Visual Studio, you can quickly check the project format using one of the following methods: Right-click the project in Solution Explorer and select Edit myprojectname. csproj.
Right Click on Project of a solution. Open Properties -> Application Tab. On the right you can see 'Output Type' which defines your project type of an existing solution.
I found a site that lists some known project type GUIDs for Visual Studio 2008.

looks like a Windows C# project (probably a Class Library project?)786C830F-07A1-408B-BD7F-6EE04809D6DB
appears to be a Portable Library project I agree that it's crazy to expect a developer to understand the project type represented by a GUID but whoever supplied the code you downloaded could have indicated what was required to build it!
Here's a list of project type GUIDs:
