Can someone help me troubleshoot C# script debugging on HoloLens please with IL2CPP? I've never had trouble with getting .NET debugging to work first time but my experience with IL2CPP has been patchy at best and it's currently broken for me. I'm building in Unity 2018.2.16f1. I have the 'Development Build', 'Script Debugging', 'Wait for Managed Debugger' options all set. I can build and deploy my code which targets SDK 10.0.17763.0. I'm running Visual Studio 15.9.2. My HoloLens is running 17763.134.x86fre.rs5_release_svc_prod1.181101-1643 and the app deploys to the device and runs up fine and displays the "you can now attach a managed debugger" dialog box. My device is on WiFi and my laptop is on a wired network that connects onto that WiFi (I have also tried my laptop on the same WiFi) and when I use the Debug->Attach Unity Debugger option in Visual Studio I see the HoloLens player as an option and I attach to it. Visual Studio goes a little busy and then the cursor resets itself and nothing seems to happen. There's no output in the Output window. The debugger doesn't seem to attach. Can someone please help me diagnose? I'm probably doing something obviously wrong or perhaps have just missed a step. I have looked into my firewall rules and (as far as I can tell) Visual Studio is allowed to accept incoming UDP and TCP connections. I have looked on the HoloLens for the UnityPlayer.log and I can find one in LocalAppData\Package\TempState\UnityPlayer.log but it seems to be 0 bytes in size. Thanks in advance!
