Cannot evaluate the property expression "$([MSBuild]::ValueOrDefault('$(VCTargetsPath)','$(MSBuildExtensionsPath32)\Microsoft.Cpp\v4.0\V140\'))" found at "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\14.0@VCTargetsPath". Invalid static method invocation syntax: "[MSBuild]::ValueOrDefault('$(VCTargetsPath)','$(MSBuildExtensionsPath32)\Microsoft.Cpp\v4.0\V140\')". Method '[MSBuild]::ValueOrDefault' not found. Static method invocation should be of the form:$([FullTypeName]::Method()), e.g. $([System.IO.Path]::Combine(`a`, `b`)).

 

原因是之前安装了VS2015，而注册表没清理干净。

I had the same issue when I had previously installed VS2013 and then uninstalled. This happens because VS2013 uninstaller forgets one of its registry keys, which causes this error when you start to work with VS2010 again.

Delete if there is a key with 12.0 in this location.

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MSBuild\ToolsVersions

Hopefully VS2010 will work again.
