Wrong xUnit runner "xunit.execution.dotnet" chosen for .NET Framework property tests

[ronnieholm]

If you create a new .NET 4.8 test project and reference

• FsCheck.3.0.0-rc3
• FsCheck.Xunit.3.0.0-rc3
• xunit.2.7.0
• Other xUnit dependencies in 2.7.0 version

then the FsCheck [<Property>] test fails while the regular [<Fact>] test succeeds.

module FsCheckBug

open Xunit
open FsCheck.Xunit

[<Fact>]
let succeeds() =
    Assert.True(true)

[<Property>]
let fails() =
    Assert.True(true)

The failure is:

System.InvalidOperationException : Exception during discovery:
System.IO.FileNotFoundException: Could not load file or assembly 'xunit.execution.dotnet, Version=2.4.1.0, Culture=neutral, PublicKeyToken=8d05b1bb7a6fdb6c' or one of its dependencies. The system cannot find the file specified.
File name: 'xunit.execution.dotnet, Version=2.4.1.0, Culture=neutral, PublicKeyToken=8d05b1bb7a6fdb6c'
   at FsCheck.Xunit.PropertyDiscoverer.Xunit.Sdk.IXunitTestCaseDiscoverer.Discover(ITestFrameworkDiscoveryOptions discoveryOptions, ITestMethod testMethod, IAttributeInfo _arg1)
   at Xunit.Sdk.XunitTestFrameworkDiscoverer.FindTestsForMethod(ITestMethod testMethod, Boolean includeSourceInformation, IMessageBus messageBus, ITestFrameworkDiscoveryOptions discoveryOptions) in /_/src/xunit.execution/Sdk/Frameworks/XunitTestFrameworkDiscoverer.cs:line 119

Two things stand out about the failure:

1. The test should've executed with xunit.execution.desktop.dll, not xunit.execution.dotnet.dll as the test project is a .NET Framework 4.8 project, not a .NET Core project.
2. The 2.4.1.0 version is wrong and should've been 2.7.0.0 as that's the version of the xunit.extensibility.execution NuGet package referenced.

Any tips on how to narrow down the cause?
