问题
Visual Studio doesn't display the project properties for a C++ project when a configuration is selected which uses vs90 as its toolset.
When I right-click a project in the affected solution and select "Properties" from the context menu, the property dialog appears empty:
I remember that it used to show normal compiler options even for older toolsets. What could cause this behaviour?
回答1:
I was able to fix it by making sure that VCTargetsPath (and corresponding VCTargetsPath12 for VS 2013 property) in MSBuild contains a trailing backslash.
Found this by monitoring the devenv.exe process using Process Monitor from sysinternals and noticed that it was trailing to load an invalid path due to missing . After adding it, the project properties started displaying correctly.

I found a similar problem - if I selected one specific build configuration in visual studio the Project Properties dialog went permanently blank and there was no way to go back to a working configuration.
The solution I eventually found was a devenv commandline option: devenv /resetuserdata
