问题 In ASP.Net / ASP.Net Core WebAPI, When the client/browser tries to access a WebAPI endpoint which is decorated with [Authorized] attribute. It gets a 302-Found status code with a redirect response to the Login page, instead of 401-Unauthorized for an unauthorized request. Note: I have noticed that Fail(AuthorizationContext context) method in AuthorizeAttribute filter sets the response code as 401-Unauthorized , but eventually browser gets a 302-Found response. How can I send the 401 response

问题 It has been well documented, how to inject dependencies into services. Question: But is it (already) possible in ASP.NET Core 2.0 to have the system's DI mechanism automatically inject a service into a method or into a property? Sidenote: In PHP-Symfony this pattern is called setter injection. Example: Say I have a common MyBaseController class for all controllers in my project and I want a service (e.g. the UserManager service) to be injected into MyBaseController that can be later accessed

问题 I wanted to set my starting page to /Members/Index. When I was using MVC, I configured it as following: app.UseMvc(routes => { routes.MapRoute( name: "default", template: "{controller=Members}/{action=Index}/{id?}"); }); But now I'm trying new Razor Pages approach, and now Members is folder and Index is Razor Page.

问题 I am very new to file transfer between HttpClient and a Web API, so please excuse any ignorance and guesswork in my code. I have been trying to post a file created with System.IO.Compression.ZipFile to my web API now for about a day, and always I get a 404 response. If I post with an empty stream, the API action method is invoked, so I know the 404 is due to content and not the URI. This method is in the client WPF application that attempts to post the file: public async Task PostDirAsync

问题 I use System.Data.SqlClient Version 4.4.3 for all .NET Standard 2.0 class libraries in my ASP.NET Core 2.0 project.

The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) when the project is published with VSTS to Azure App Service?

问题 It works well with the label "2" outside of default website but it does run inside the default website 回答1: Try the following... Install the hosting bundle again, and then publish from Visual Studio again. If that doesn’t fix it, go to the publish output folder and run dotnet run <YourWebDll>.DLL 回答2: I assume you already install either SDK or Runtime in web server. Then, you need to install ASP.NET Core Module in web server. Here is the download link. Trouble Shooting If it still doesn't
