assemblyinfo attributes are not generated from fsproj

ref https://github.com/GoogleCloudPlatform/google-cloud-dotnet/issues/863

Attributes like TargetFrameworkAttribute, Version, FileVersion should be auto generated as temporary AssemblyInfo.fs passed to compiler

that's a regression from .net core sdk preview2

atm is not implemented at all.

As a workaround, these can be manually generated. From https://github.com/GoogleCloudPlatform/google-cloud-dotnet/issues/863#issuecomment-285860239, create a new source file (file name doesnt matter)

namespace System

[<assembly:System.Runtime.Versioning.TargetFrameworkAttribute(".NETCoreApp,Version=v1.1")>]
do ()

and add it as Compile item, like <Compile Include="AssemblyInfo.fs" />

how to fix it: we need to implement F# support in WriteCodeFragment tasks https://github.com/Microsoft/msbuild/blob/master/src/Tasks/WriteCodeFragment.cs

is just a foreach over assemblyattributes, in the switch (for coreclr), like c# does, no codedom needed

Same file for msbuild full codegen

How were these attributes getting created before?

@baronfel--just trying to see how necessary it is to bake support for every language into core MSBuild tasks.
