For .NET 7 support, stay on the latest v7.x.x version. For bug fixes in v7, please PR and we'll release updates.

More details: #9511

Dialog

DialogOptions is now an immutable record. Use SetOptionsAsync and with to modify DialogOptions:

[CascadingParameter]
private IMudDialogInstance MudDialog { get; set; }

private Task ToggleFullscreenAsync()
{
    var options = MudDialog.Options with
    {
        FullScreen = !(MudDialog.Options.FullScreen ?? false)
    };

    return MudDialog.SetOptionsAsync(options);
}

KeyInterceptor

IKeyInterceptor / KeyInterceptor, IKeyInterceptorFactory / KeyInterceptorFactory were removed and replaced with KeyInterceptorService. More details: #9896

KeyOptions is now immutable. More details: #9969

MudPopoverService

Removed from the core, replaced by PopoverService. The MudPopoverService was legacy, provided only for cases where you might encounter issues with PopoverService. If you encounter issues, please submit an issue.

More details: #9957

DialogService

• Removed OnDialogInstanceAdded, use DialogInstanceAddedAsync instead. #9980

Converters

In Converter.cs, several property signatures have been updated to enhance localization support. These properties no longer return English messages directly. Instead, they now return keys intended for localization, accompanied by additional parameters:

• OnError: Updated from Action<string>? to Action<string, object[]>?. This allows passing a key and optional parameters, enabling more flexible and accurate localization.
• SetErrorMessage and GetErrorMessage: Both changed from string? to (string, object[])?. These properties now provide a key for localization along with relevant parameters, shifting message formatting to the localization system.

EventUtil

The following API has been removed:

EventUtil.AsNonRenderingEventHandler(...)

It has been replaced with:

this.AsNonRenderingEventHandler(...)

Because this is now an extension method that requires a reference to ComponentBase. The previous EventUtil.AsNonRenderingEventHandler did not propagate exceptions to ErrorBoundary (see dotnet/aspnetcore#54543). The new method ensures that exceptions are properly handled and propagated.

MudChip

The MudChip now renders a semantic anchor tag in place if the div if an href is specified. It can now be a true anchor and so no longer acts like a button. The browser now handles the click (and Enter key) so OnClick is disabled and the close button is no longer shown (if applicable). This improves accessibility, including allowing the user to hover it to see the link it will direct them to, middle click to open in a new tab, or drag to another place.

Localization

In DefaultLocalizationInterceptor we removed:

LocalizedString TranslationFallback(string key)

use instead:

LocalizedString TranslationWithFallback(string key, params object[] arguments)

Note: Legacy keys were removed:
