问题


I am trying to remote debug an Asp.Net Core Web Application (with Web API) project deployed as an Azure App Service with Visual Studio 2017 Professional.

Followed the instructions as documented here. Essentially, using the Server Explorer-->App Service-->Attach Debugger

Also, enabled the necessary firewall ports as mentioned. The ones I opened are TCP (4022, 4023) and UDP (3702). Also, ensure remote debugger application is in allowed list of apps in Windows Firewall. Documentation for the firewall steps.

Despite all the settings, I am getting following error

System.Runtime.InteropServices.COMException (0x89710023): Unable to connect to the Microsoft Visual Studio Remote Debugger named 'essamplepoc2.azurewebsites.net'. The Visual Studio 2017 Remote Debugger (MSVSMON.EXE) does not appear to be running on the remote computer. This may be because a firewall is preventing communication to the remote computer. Please see Help for assistance on configuring remote debugging. at Microsoft.VisualStudio.Debugger.Interop.Internal.IDebuggerInternal120.ConnectToServer(String szServerName, VsDebugRemoteConnectOptions[] pConnectOptions, CONNECT_REASON ConnectReason, Int32 fIncrementUsageCount, IDebugCoreServer3& ppServer) at Microsoft.VisualStudio.Web.Azure.MicrosoftWeb.Operations.RemoteDiagnosticsSessionBase.ConnectToServer(String site, String user, String password)

Any suggestion would be helpful.

The issue is resolved. We had to open outbound ports 4022 for VS 2017 and 4020 for VS 2015 on corporate firewall.

I also had this problem. I solved it by changing the Platform from 32-bit to 64-bit in Application Settings as I am trying to debug from 64-bit machine.

It seems remote debugging is not turned on for your App Service.

Open your App Service in the Azure portal and go to Application Settings. Then turn Remote Debugging to On and select Visual Studio Version to 2017.

It should look like this: Screenshot source

I hope this helps.
