StatusCodePagesMiddleware in ASP.NET Core

StatusCodePagesMiddleware converts raw error status codes into user-friendly error page. 

It can be used like this: app.UseStatusCodePages(); or app.UseStatusCodePagesWithReExecute("/error/{0}");

StatusCodePagesMiddleware re-executes the pipeline to generate an HTML body for a 4xx/5xx response. For example, if a request to the /Home path returns a 404 response, the pipeline is re-executed using the /error/404 path to generate the HTML response.

So I started like this: using ( var workItemTrackingHttpClient = new WorkItemTrackingHttpClient ( new Uri ( " http://mytfs/tfs/Plato " ) , new VssCredentials ( ) ) ) { try { var items = workItemTrackingHttpClient . QueryByIdAsync ( new Guid ( " 25c6e737-d0ce-416f-9f7a-3cb78959334d " ) ) . Result .
