Blazor IDisposable not working

[rborosak]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

IDisposable is not working when the component implements both IDisposable and IAsyncDisposable.

Based on the empty Blazor Server project

public partial class Counter : IDisposable, IAsyncDisposable
{
public void Dispose() {}
public ValueTask DisposeAsync(){ return ValueTask.CompletedTask; }
}

Only DisposeAsync method is called.

Expected Behavior

Both Dispose and DisposeAsync should be called.

.NET Version

.NET 6

@rborosak thanks for contacting us.

When you implement IAsyncDisposable it is preferred over IDisposable the expectation is that you fully dispose the object in both cases. It is expected that Dispose is called within the DisposeAsync, see here for details
