解决【the project file'xxxx'cannot be opened.the project type is not supported by this installation.】
I found I had to do all the steps mentioned, namely
1) devenv /setup
2) regsvr32.exe "%vs80comntools%/../IDE/projectaggregator.dll"
3) Then download
2) regsvr32.exe "%vs80comntools%/../IDE/projectaggregator.dll"
3) Then download
also called "Microsoft Visual Studio 2005 - Update to Support Web Application Projects"
It was probably all important, however crucially I also had to run the command line
installed WebApplicationProjectSetup.msi.
4) devenv /resetskippkgs
which is listed in the rather unfriendly error message that Visual Studio displays.
Obviously at some point I had clicked the 'Yes' button and not the 'No' button when trying to get this to work.
I did not have the "web application" option for new projects, so I installed
and that fixed my issue with loading the .csproj
之前是因为先装了VS2008再装VS2005的时候打开web项目报“the project file'xxxx'cannot be opened.the project type is not supported by this installation.”的错误,按上面的几个步骤走,问题解决,希望可以帮到同样问题的人~
