Cannot debug

[uecasm]

Describe the bug: Pressing F5 to start debugging opens a new Chrome window to about:blank, and displays some DLL loading messages in the debug console. Nothing else happens. Clicking Stop Debugging does nothing; it does not appear to be possible to terminate the debugging session in any way other than using Close Window.

Version used:

• .NET SDK (6.0.200)
• Visual Studio Code 1.64.2 (also happens in 1.65.0)
• C# 1.24.1
• Microsoft.AspNetCore.Razor.VSCode.BlazorWasmDebuggingExtension 1.1.0

To reproduce: Steps to reproduce the behavior:

1. Create a new Blazor WebAssembly app using the dotnet command line dotnet new blazorwasm -o BlazorApp --no-https
2. dotnet build/run/watch work as expected
3. Install VSCode, C#, and wasm debugging extensions and open the folder for the above
4. It prompts to create debugging files, click Yes
5. Press F5

Expected behavior: Opens the app and allows debugging, and allows debugging to stop

Actual behavior: Doesn't open the app (just a blank Chrome window) and ignores attempts to stop debugging

Additional context: Generated launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch and Debug Standalone Blazor WebAssembly App",
            "type": "blazorwasm",
            "request": "launch",
            "cwd": "${workspaceFolder}/BlazorApp"
        }
    ]
}

This appears to be related to #6072, which was closed as "fixed" but does not seem to be fixed...

FWIW, debugging does appear to work as expected in VS2022.

Same issue here. Not being able to debug on vscode seems pretty big tbh.

[DanielHazlewood]

Hmm. Looks like this is due to vscode razor extension not being published in a while, I built a version locally off latest and I'm able to debug wasm now.

The last publish of the Microsoft.AspNetCore.Razor.VSCode.BlazorWasmDebuggingExtension extension was in 05/21/2021, .NET 6 arrived in Nov/2021... there are any plans to update and publish the official extension?
