Debugging asp .NET Core 5 beta in Azure

Question

Is it possible to debug an asp .net core 5 beta web app running on azure? I've been getting this error since I tried to do this. System.Runtime.InteropServices.COMException (0x89710023): Unable to connect to the Microsoft Visual Studio Remote Debugger named 'blahblahblah.azurewebsites.net'. The connection with the remote endpoint was terminated.

at Microsoft.WebTools.Azure.VS.Operations.IDebuggerInternal120.ConnectToServer(String szServerName, VsDebugRemoteConnectOptions[] pConnectOptions, CONNECT_REASON ConnectReason, Int32 fIncrementUsageCount, IDebugCoreServer3& ppServer) at Microsoft.WebTools.Azure.VS.Operations.RemoteDiagnosticsSessionBase`1.ConnectToServer(String site, String user, String password)

I should also add that my build is debug, my app service is set for remote debugging, and my publishing type is set to self contained. IIRC, self contained puts everything into a directory and deploys it to azure. I think all are correct for trying to debug. — Wallace B. McClure

I've had similar challenges on .netcore5 with exact same error message. I've checked all the criteria like DEBUG build, having the right App Service Plan Level, ensuring remote debug is enabled in Azure, using both Cloud Explorer as well as the classic Attach Process, toggling Deployment mode (framework vs. self contained) even ensuring ensuring matches of 32 vs 64 bit server/client and running VS2019 in admin mode.

Been chasing this all weekend but am planning to just set it aside and try again when .net5 has moved out of (early access) status
