This was attempted before but the testnost apphost was too old to undestand the architecture specific dotnet_root: https://github.com/microsoft/vstest/pull/3715/files |

Description
Use
VSTEST_DOTNET_ROOT_PATHandVSTEST_DOTNET_ROOT_ARCHITECTUREthat will receive the location of dotnet.exe from the dotnet SDK.When we find testhost.exe we will set env variables based on the version of testhost, to make sure that old testhost gets dotnet_root and new one gets dotnet_root_ so they can pick up local installation of dotnet.
