This code is the skeleton I was looking for when I posed the question. It uses only facilities available in .NET Core. var watcher = new BluetoothLEAdvertisementWatcher(); var logPath = System.IO.Path.GetTempFileName(); var logFile = System.IO.File.Create(logPath); var logWriter = new System.IO.StreamWriter(logFile); logWriter.WriteLine(“Log message”); logWriter.Dispose();
You could pass in the desired ASPNETCORE_ENVIRONMENT into the dotnet publish command as an argument using: /p:EnvironmentName=Staging e.g. dotnet publish /p:Configuration=Release /p:EnvironmentName=Staging This will generate out the web.config with the correct environment specified for your project: <environmentVariables> <environmentVariable name=”ASPNETCORE_ENVIRONMENT” value=”Staging” /> </environmentVariables>

The only IL change is: // … L_0040: ldc.i4.0 L_0041: stloc.3 … Read more
