title: Blazor equivalent of WPF ShowDialog()?
body: <p>I'm attempting to migrate some code from WPF to Blazor.  The WPF code relied on ShowDialog() to display a modal dialog and suspend execution until the modal was closed.  Is there a (server-side) Blazor equivalent that allows C# flow of control to be based, for example, on whether the user clicked Acknowledge vs Cancel in a modal dialog?</p>
