Node.js 20 actions are deprecated. The following actions are running on Node.js 20 and may not work as expected: actions/checkout@v4, actions/setup-dotnet@v4, microsoft/setup-msbuild@v2. Actions will be forced to run with Node.js 24 by default starting June 16th, 2026. Node.js 20 will be removed from the runner on September 16th, 2026. Please check if updated versions of these actions are available that support Node.js 24. To opt into Node.js 24 now, set the FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true environment variable on the runner or in your workflow file. Once Node.js 24 becomes the default, you can temporarily opt out by setting ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true.

Dereference of a possibly null reference.

Dereference of a possibly null reference.

Converting null literal or possible null value to non-nullable type.

Unreachable code detected

Non-nullable event 'CanExecuteChanged' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the event as nullable.

Cannot convert null literal to non-nullable reference type.

Nullability of reference types in type of 'event EventHandler AsyncRelayCommand.CanExecuteChanged' doesn't match implicitly implemented member 'event EventHandler? ICommand.CanExecuteChanged'.

Nullability of reference types in type of parameter 'parameter' doesn't match implemented member 'bool ICommand.CanExecute(object? parameter)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'parameter' doesn't match implemented member 'void ICommand.Execute(object? parameter)' (possibly because of nullability attributes).
