Documentation for microsoft.net.compilers package (at https://www.nuget.org/packages/Microsoft.Net.Compilers/) says
.Net Compilers package. Referencing this package will cause the project to be built using the specific version of the C# and Visual Basic compilers contained in the package, as opposed to any system installed version.
... which begs the question: what version of the compiler is in the package?
That same page says that it supports .NET framework 4.5, but that's not the compiler version, is it?
There are several versions of the package. I assume then that different versions of the package may contain different versions of the compiler. Is there a table somewhere that specifies which compiler version is in each package version?
I guess the package contains both c# and vb compilers, but I'm only interested in c#.

NET Compiler Platform, also known by its codename Roslyn, is a set of open-source compilers and code analysis APIs for C# and Visual Basic (VB.NET) languages from Microsoft.
NET uses two compilers, Roslyn, to compile C# or VB code into CIL (common intermediate language), and RyuJIT, to run just-in-time compilation of CIL into native code. Both compilers are highly regarded by the . NET community as Microsoft actively improves them.
Compilers. Toolset. ` This package is primarily intended as a method for rapidly shipping hotfixes to customers. Using it as a long term solution for providing newer compilers on older MSBuild installations is explicitly not supported.
The . NET Compiler Platform SDK enables you to build analyzers and code fixes that find and correct coding mistakes. Analyzers understand the syntax (structure of code) and semantics to detect practices that should be corrected.
