Method overload completion no offered when expect in Razor file and generated code is incorrectly formatted or missing method body

[danroth27]

Type: Bug

• Create a Blazor Web App
• In Counter.razor try to add a method overrload for OnInitialized() by typing override and then a space in the code block.

Expected result: Completion list offers list of methods to override like it does in VS
Actual result: No completion list
Workaround: Start typing the desired method to override.

• Start typing OnInitialized and then select the method from the completion list.

Expected result: Method is generated with correct formatting.
Actual result: Generated override is incorrectly indented:

@code {
    private int currentCount = 0;

        protected override void OnInitialized()
        {
            base.OnInitialized();
        }
        private void IncrementCount()
    {
        currentCount++;
    }
}

• I've also seen some cases where I complete OnInitialized() and it only completes the method name and not the method body. But this doesn't repro reliably:

Error from the output window:

This issue has been marked as stale after 14 days of inactivity. @[ @ @], could you please take a look?

[ryzngard]

I also have seen where inserting the completion does not work at all. This was in a WSL environment with version v2.39.29

@alexgav moving to October milestone, as August is closed.

This is very likely to be an issue from the LSP server as we have the same issue as ryzngard in neovim using Roslyn. Here it doesn't work even for normal C# code, so I expect that it was somehow partially patched directly in vscode
