Rx support for Blazor applications. It allows you to subscribe to an observable and asynchronously provide values in the razor syntax.
Put the code, that depends on the asynchronous value, inside the Subscribe element and pass the source observable as the To attribute parameter.
<Subscribe To="@MyObservable">
<p>This is the code that needs async values from the MyObservable. The value provided is: @context and is continuously updated as the observable emits more elements.</p>
</Subscribe>
