Try to run Omnisharp.exe in cmd and it show found 1 Standalone MsBuild. Then it print some error:

I do not have VS. So the MSBuild Locator for VS could not work.I just find MsBuild in C:\Windows\Microsoft.NET\Framework64\v4.0.30319\MSBuild.exe.How could I config the path to OmniSharp.

I have installed Visual Studio,and Omnisharp server finilly start up.So we can not use Omnisharp server without Visual Studio?
