.net-core-3.0

问题 I am trying to change change a string, being used for a title, in my blazor-server-side application. But I am having trouble getting the UI to update. I tried using StateHasChanged(), but that didn't work so I looked around and found that on the FlightFinder Demo that was made, it has an OnChange event Action, so I am trying to implement that. It works until I try to refresh the browser, then I am hit with this error System.InvalidOperationException: 'The current thread is not associated with

问题 Does anyone know how to publish a .NET Core 3.0 application for ARM64? I can only select "linux-arm" but no "linux-arm64". Setting linux-arm in combination with x64 also doesnt work. It says the settings are not compatible. As stated here it should already be supported: https://github.com/dotnet/core/blob/master/release-notes/3.0/3.0-supported-os.md 回答1: The linked article points to the supported OSs, not the list of runtime identifiers. An explanation of an RID and a list of common ones can
