RemoteDebugWebApplication

This project is an attempt to automate the build and debug process of an aspnetcore application for a Raspberry Pi.

Prerequisites

AspNetCore 3.1 runtime on the Raspberry Pi

The project assumes you have .netcore3.1 runtimes installed on the Raspberry Pi. How-to: https://edi.wang/post/2019/9/29/setup-net-core-30-runtime-and-sdk-on-raspberry-pi-4

Passwordless SSH

It is assumed that you have previously setup SSH and the Raspberry Pi for passwordless connection. See https://www.raspberrypi.org/documentation/remote-access/ssh/passwordless.md

or https://blogs.endjin.com/2019/09/passwordless-ssh-from-windows-10-to-raspberry-pi/

Visual Studio Remote Debugging tools

You need to install the remote debugging tools on the Raspberry Pi.

See https://www.hanselman.com/blog/RemoteDebuggingWithVSCodeOnWindowsToARaspberryPiUsingNETCoreOnARM.aspx

I've set it up so it starts when the Raspberry Pi boots. I don't remember how I did that though.....

Profiles

The project has 2 profiles: "IISExpress" and "RemoteDebugWebApplication".

• "IISExpress" will build and debug the project for the local computer as normally.
• "RemoteDebugWebApplication" will build and publish the project locally for linux-arm archtecture, and then copy and start the project on a Raspberry Pi.

"RemoteDebugWebApplication" profile

When starting this profile, the project will be built and published to the local folder 'RemoteDebugWebApplication\bin\Debug\netcoreapp3.1\linux-arm\publish'

NB: The publish step is configured for 'Framework dependent' rather than 'Self-contained', otherwise the entire framework should be copied to the Raspberry Pi.

These files are then copied to the Raspberry Pi. Then the project is started on the Raspberry Pi.

The magic that makes this all happen are the files:

• publish.bat
• Properties\launchSettings.json
• Properties\PublishProfiles\RemoteDebug.pubxml

How to debug

You must start the debugging process by attaching to the project's process on the Raspeberry Pi.

• Choose 'Debug' -> 'Attach to process'
• Connection type: 'SSH'
• Connection target: username@ip address of the Raspberry Pi, e.g. [email protected]

When you stop debugging in VS2019, the process remains running on the Raspberry Pi.

You may kill it on the Raspberry Pi, but also the "RemoteDebugWebApplication" profile will try to kill it before uploading a new version.

Alternatives

This VS2019 extension seems to work okay:
