Blazor (server-side) System.InvalidOperationException: Received a notification for a rendered batch when not expecting it.
See original GitHub issueI`ve got an Blazor server-side app deployed as self-contained (dotnet 3.0 preview4) on Azure AppServices.
It seems to run fine on simple Pages (counter with additional buttons or the weather forecast displayed in an pageable datagrid), but it dies after 0-5 UI interactions on a more advanced page.
In the browser-console the following error occurs and after that error the signalR connection is disconnected (without the automatic reconnection kicking in):
On my local dev maschine no such error occured even once.
To see this error happening open this link to the deployed webApp and click on some button or dropdowns, after some UI interactions the error should occur in the browser console.
If needed the source code for this app is located here.
Same error as reported in this comments: https://devblogs.microsoft.com/aspnet/asp-net-core-updates-in-net-core-3-0-preview-4/#comments-367

If I understand correctly, the PR that fixed this (#10506) has been reverted, so this issue should be reopened. Assigning to preview 7.
@pranavkm Please let me know (or just close this) if I’m misunderstanding and this actually is being handled in preview 6 still.
@BrennanConroy Great thank you.
