3.90 source code building

Hello,

I downloaded the source codes of 3.90. Unblocked the rar, extract to a folder and tried to build the solution but get this error:

An attempt was made to load an assembly with an incorrect format: C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.1\Facades\System.Reflection.Emit.dll.  Nop.Services  C:\Working\NopCommerce\Libraries\Nop.Services\SGEN    

I'm using Visual Studio 15.4.1 and my build log related to this error is below:

3>SGEN : error : An attempt was made to load an assembly with an incorrect format: C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.1\Facades\System.Reflection.Emit.dll.
3>    - Could not load file or assembly 'file:///C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.1\Facades\System.Reflection.Emit.dll' or one of its dependencies. The module was expected to contain an assembly manifest.

I also tried x86 as project target but that doesn't solved the problem.

Any help?
