ASP.NET :4.0.30319.18446

I would like to find out what's wrong? Does it have to be installed .net 4.6?

I've found some linked solution, but is there no other more elegant way to solve this problem?

I've found the answer to my question :)

Practice Results: The Roslyn compiler is supported in diffrent .net versions, but

• Microsoft.Net.Compilers (< 2) supports minimum core c#6.0 syntax and needs >= .net 4.5
• Microsoft.Net.Compilers (>= 2) supports full c#6.0 and higher syntax, need at least .net 4.6
