dotnet location when fsproj is called from msbuild .net full

[enricosada]

fsproj need to call netcoreapp fsc, and is doing that with /path/to/dotnet.exe /path/to/fsc

Atm doesnt exists a property from msbuild/sdk who give dotnet path, ref #75 (comment)

When called from .NET Core sdk (dotnet msbuild) or mono (after #75) the path of dotnet location is relative to $(MSBuildSDKsPath) because works ok for mono/netcore.

But is not enough for msbuild (.net full) installed by VS, and sdk path is %PROGRAMFILES(X86)%\Microsoft Visual Studio\2017\Enterprise\MSBuild\Sdks\

Proposed solution is just dotnet, resolved from PATH (only for win/netfull atm based on $(MSBuildRuntimeType) ) so will use global.json if the installed dotnet is the one in PATH.

That's because i cannot find a relative path who can work.

Maybe make mandatory this solution for everyone (mono/netcoresdk) can be ok too. less corner cases.

But will make dotnet resolution fragile, so running my/binaries/but/not/in/PATH/dotnet.exe fsproj may use a wrong dotnet (ref bug #65). so tradeoff

Any ideas for VS? just use global.json and PATH? @eerhardt @rainersigwald @jeffkl @nguerrera @dsplaisted @piotrpMSFT

fixed by #100

Now when msbuild host is .NET Full, the fsc.exe (in tools) is run.
