Error: ./Assets/websocket-sharp/websocket-sharp.csproj: ./Assets/websocket-sharp/websocket-sharp.csproj could not import "$(MSBuildBinPath)\Microsoft.CSharp.targets" (websocket-sharp)

Hi, I have had the same problem and solved using xbuild. If you installed unity, you should use xbuild command.

In command line,

xbuild (path to websocket-sharp project path)/websocket-sharp.sln

however, it will probably display warning and error messages.

They are "Microsoft.Common.tasks not found" and "Microsoft.CSharp.targets not found". You need to link Microsoft.Common.tasks and Microsoft.CSharp.targets.

For example, my development environment is

:  warning : Default tasks file /Library/Frameworks/Mono.framework/Versions/4.2.3/lib/mono/3.5/Microsoft.Common.tasks not found, ignoring.
/Users/Tsuyoshi/WorkSpace/github/websocket-sharp/websocket-sharp/websocket-sharp.csproj:  warning : Could not find project file /Library/Frameworks/Mono.framework/Versions/4.2.3/lib/mono/3.5/Microsoft.CSharp.targets, to import. Ignoring.
Project "/Users/Tsuyoshi/WorkSpace/github/websocket-sharp/websocket-sharp.sln" (default target(s)):
    Target ValidateSolutionConfiguration:
: error : Error initializing task Message: Not registered task Message.
        Build FAILED.
        Warnings:
        :  warning : Default tasks file /Library/Frameworks/Mono.framework/Versions/4.2.3/lib/mono/3.5/Microsoft.Common.tasks not found, ignoring.
        /Users/Tsuyoshi/WorkSpace/github/websocket-sharp/websocket-sharp/websocket-sharp.csproj:  warning : Could not find project file /Library/Frameworks/Mono.framework/Versions/4.2.3/lib/mono/3.5/Microsoft.CSharp.targets, to import. Ignoring.
        Errors:

             2 Warning(s)
             1 Error(s)
        Time Elapsed 00:00:00.1988430

As below, 

sudo ln -s /Library/Frameworks/Mono.framework/Versions/4.2.3/lib/mono/4.5/Microsoft.Common.targets /Library/Frameworks/Mono.framework/Versions/4.2.3/lib/mono/3.5

sudo ln -s /Library/Frameworks/Mono.framework/Versions/4.2.3/lib/mono/4.5/Microsoft.CSharp.targets /Library/Frameworks/Mono.framework/Versions/4.2.3/lib/mono/3.5

I have fixed the link of Microsoft.Common.targets and Microsoft.CSharp.targets. Build again, it might be successful.

Thank you.
