Extensions.Hosting tests failing in VS Test Explorer

[eerhardt]

Repro steps

• dotnet build .\src\libraries\Microsoft.Extensions.Hosting\tests\
• .\build.cmd -vs .\src\libraries\Microsoft.Extensions.Hosting\Microsoft.Extensions.Hosting.sln
• Open the Test Explorer window
• Run all tests

Expected results

All tests should pass clean

Actual results

Tests that depend on EventLog fail with:

System.PlatformNotSupportedException : EventLog access is not supported on this platform.

  Stack Trace: 
    EventLog.ctor(String logName, String machineName, String source) line 30
    WindowsEventLog.ctor(String logName, String machineName, String sourceName) line 20
    EventLogSettings.CreateDefaultEventLog() line 61
    EventLogSettings.get_EventLog() line 39
    EventLogLogger.ctor(String name, EventLogSettings settings, IExternalScopeProvider externalScopeProvider) line 37
    EventLogLoggerProvider.CreateLogger(String name) line 50
    LoggerInformation.ctor(ILoggerProvider provider, String category) line 72
    LoggerFactory.CreateLoggers(String categoryName) line 199
    LoggerFactory.CreateLogger(String categoryName) line 131
    Logger`1.ctor(ILoggerFactory factory) line 29

Analysis

It appears the Test Explorer window is not respecting the TFMs in Hosting:

runtime/src/libraries/Microsoft.Extensions.Hosting/tests/UnitTests/Microsoft.Extensions.Hosting.Unit.Tests.csproj

Line 4 in 671f99b

<TargetFrameworks>$(NetCoreAppCurrent)-Windows_NT;$(NetCoreAppCurrent);net461</TargetFrameworks>

It should only be running the tests for $(NetCoreAppCurrent)-Windows_NT, but it looks like it is running for both $(NetCoreAppCurrent)-Windows_NT and $(NetCoreAppCurrent)

@Anipik, test configurations aren't filtered in VS.

@Anipik you are assigned to this issue. Can you please take a look?

@carlossanlop @ericstj as you have an offline thread going on with the VS Test Explorer team. Is this related?
