The host process is created and runs correctly, but it does not stop at breakpoints in the console app. I am using Visual Studio 2017 15.9.6.I have created a simple console app and a unit test project. The console app is the same as the one in the TestPlatform.Playground readme. The unit test project references the console app and contains the following test:When I run the test, the test host process is created, but it does not stop at the breakpoint in the console app. I have tried both the "Managed (CoreCLR, CoreFX)" and "Native (Windows only)" debuggers in Visual Studio, but neither of them work. I have also tried setting the "Enable Just My Code" option in Visual Studio to both "Yes" and "No", but neither of those options work either. I have also tried running the test from the command line using the "dotnet test" command, but that does not work either. The test host process is created, but it does not stop at the breakpoint in the console app. The test host process exits immediately after it is created. I have also tried setting the "Debugging" property of the test project to "Project", but that does not work either. I have also tried setting the "DebugType" property of the console app to "Full", but that does not work either. I have also tried setting the "DebugType" property of the console app to "Embedded", but that does not work either. I have also tried setting the "DebugType" property of the console app to "Portable", but that does not work either. I have also tried setting the "DebugType" property of the console app to "PdbOnly", but that does not work either. I have also tried setting the "DebugType" property of the console app to "None", but
