If you have .NET v4 installed (so if you have a newer windows or if you apply the windows updates)
C:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe somefile.cs
or
C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild.exe nomefile.sln
or
C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild.exe nomefile.csproj
It’s highly probable that if you have .NET installed, the %FrameworkDir%
variable is set, so:
%FrameworkDir%\v4.0.30319\csc.exe ...
%FrameworkDir%\v4.0.30319\msbuild.exe ...
