ASP.NET MVC project "not supported by this installation"
提问by roundcrisis
I can create new MVC projects and they work and run however trying to open an existing project is not working at all
我可以创建新的 MVC 项目，它们可以工作并运行，但是尝试打开现有项目根本不起作用
I tried the following changing the project type to:
我尝试了以下将项目类型更改为：
<ProjectTypeGuids>{F85E285D-A4E0-4152-9332-AB1D724D3325};{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>
(this worked on migrating a project from Asp.Net MVC preview 1 to preview 2 BTW)
（这适用于将一个项目从 Asp.Net MVC 预览版 1 迁移到预览版 2 BTW）
Changed the Reference to:
将参考更改为：
<Reference Include="System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
<SpecificVersion>False</SpecificVersion>
</Reference>
I tool this from a new project I created so i know that should be ok ( i even hardcoded the path to the same result)
我从我创建的一个新项目中使用了这个工具，所以我知道应该没问题（我什至将路径硬编码为相同的结果）
Still i get the dreaded
我仍然感到害怕
The project file '.....csproj' cannot be opened. The project type is not supported by this installation.
无法打开项目文件“.....csproj”。此安装不支持该项目类型。
I also tried devenv /setupand installing the sp1 for visual studio
我还尝试devenv /setup安装了 Visual Studio 的 sp1

the first parameter in the ProjectTypeGuidsto {F85E285D-A4E0-4152-9332-AB1D724D3325}so it looks like
好的，问题是变化太多，我再次解压缩解决方案，只是将ProjectTypeGuidsto 中的第一个参数更改为{F85E285D-A4E0-4152-9332-AB1D724D3325}看起来像
<ProjectTypeGuids>{**F85E285D-A4E0-4152-9332-AB1D724D3325**};{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>

我可以看到项目欢呼！

Just had a similar problem when taking an older MVC / Azure WebRole project into VS 2012 with MVC4. The trick was to edit the .CSPROJ like this:
使用 MVC4 将旧的 MVC/Azure WebRole 项目引入 VS 2012 时遇到了类似的问题。诀窍是像这样编辑 .CSPROJ：
10c11
< <ProjectTypeGuids>{F85E285D-A4E0-4152-9332-AB1D724D3325};{349c5851-65df-11
da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>

da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>
i.e. change the first one from {F8... to {E3E3... (which is apparently MVC4). This has to be done outside of Visual Studio, in a text editor, and then open the solution and "Reload" the project that gave an error - this will trigger VS to migrate it to VS 2012.
即将第一个从 {F8... 更改为 {E3E3...（显然是 MVC4）。这必须在 Visual Studio 之外的文本编辑器中完成，然后打开解决方案并“重新加载”出现错误的项目 - 这将触发 VS 将其迁移到 VS 2012。
