Normally, I wrap the Stream in a using statement, but, in this case, I need to return it. Does it still get Disposed after I return it?

MVC6 introduces Tag Helpers which is a better way compared to using @Html.EditorFor, etc. However I have not found any Tag Helper that would be an alternative to @Html.DisplayFor. Of course I can use a variable directly on a Razor page, such as @Model.BookingCode. But this does not allow to control formatting. With MVC6, what's conceptually correct way for displaying a value of a model property? You can create your own tag helper namespace MyDemo.TagHelpers { [HtmlTargetElement("p", Attributes = ForAttributeName)] public class DisplayForTagHelper : TagHelper { private const string

I did ping the ASP.NET team and asked them how they proceeded to do their tests. Short answer You can't unit test without mocking the world. You have to do integration/functional tests. Slightly longer answer Routing can

I am trying to access appsetting.json file from a class library. So far the solution that I found is to create a configuration class implementing interface IConfiguration from Microsoft.Extensions.Configuration and add the json file to class and read from the same. var configuration = new Configuration(); configuration.AddJsonFile("appsetting.json"); var connectionString= configuration.Get("connectionString"); This seems to be bad option as we have to add the json file each time we have to access the appsetting configuration. Dont we have any alternative like ConfigurationManager in ASP.NET .
