I'm trying to resolve build failed error.
Build output (with Detailed verbosity) contains only
Build failed.
Build: 1 error, 0 warnings
IDE logs (Help > Open log directory):

XS reinstall and Microsoft Build Tools 2015 reinstall doesn't solve the problem.

Thanks for help.
Looks like solution is:- install .Net Framework 4.5.1 Developer Pack (https://www.microsoft.com/en-us/download/details.aspx?id=40772)
- repair Xamarin (not Xamarin Studo)

Can you create a C# console project, target .NET 4.5.1, and then build it from the command line with msbuild?
"Hello World" console project targeted at "Mono / .NET 4.5"
were successfully build from command line with
C:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe
mscorlib.dll at output dir have version 4.0.30319.18408
More info about Build error from ide logs:

Try v4.5.1 in your console project and compile that using msbuild from the command line.
Build test project from commandline with
aslo succeded (mscorlib.dll version 4.6.1055.0).
For the same test project Xamarin Studio shows (Build > General):
