However I also want to validate the token for a WebSocket request which of course won't work with the [Authorize] attribute. I have setup my middleware pipeline like this: app.UseWebSockets(); app.Use(async (http, next) => { if (http.WebSockets.IsWebSocketRequest == false) { await next(); return; } /// Handle

问题 I have an existing app that I am trying to upgrade from MVC5/EF6 to MVC6/EF7. We dynamically create some of our SQL tables, and as a result, have made use of the System.Data.Entity.Database.SqlQuery method to automatically map to entities that we use throughout our application. This method seems to have gone away (i.e. not part of Microsoft.Data.Entity.Infrastructure.Database ) in EF7 (or is not yet implemented). Are there plans to re-implement this method in EF7 or is there another way to

问题 I've been reading about the new support for Tag Helpers in MVC 6 and now need to create my own. I see that the built in tag helpers for existing HTML elements are all prefixed with "asp-" For example: <a asp-controller="Home" asp-action="Index">Home</a> But what about my own custom tag helpers.

问题 I seem to be unable to change the return content-type of my controller-method in the new Asp.net MVC 6. I tried various variations on: Context.Response.Headers.Add("Content-type", "text/x-vcard"); In the old WebApi days I could use this, and change the formatter: return Request.CreateResponse(HttpStatusCode.OK, data, JsonMediaTypeFormatter.DefaultMediaType); Could I do something similar in MVC 6? 回答1: You can do that by setting the Produces("ResultType") attribute on the controller action.

问题 After installing VS 2015 CTP 6 it added the following url to Available Package Sources: https://api.nuget.org/v3/index.json and turned off the following: https://www.nuget.org/api/v2/ When it did this it stopped downloading all nuget packages.

NOTE: I did upgrade the Nuget Package Manager after installing VS 2015 CTP 6. Is anyone else having this issue?
