Currently the view.RenderAsync method is executed within a try block. Thus, if an exception is thrown during rendering, no error message is displayed which makes it hard to track.

Is your feature request related to a problem? Please describe.

In a custom html helper which internally uses HtmlHelper.Editor, if the editor view is misconfigured and throws an exception, instead of showing a meaningful exception message, the html helper simply has no output which is confusing and a nightmare to track down.

Describe the solution you'd like

try
{
    viewContext.Writer = writer;

    DiagnosticListener.BeforeView(view, viewContext);

    await view.RenderAsync(viewContext);

    DiagnosticListener.AfterView(view, viewContext);
}
catch
{
    if (viewContext.PropagateExceptions)
    {
         throw;
    }
}
finally
{
    viewContext.Writer = oldWriter;
}
