问题 I am following this tutorial: http://www.asp.net/vnext/overview/aspnet-vnext/create-a-web-api-with-mvc-6 to setup a web api and I have not made it very far. Once I added the line: services.addMvc(); I got an exception saying this method is not found. I searched online and found a separate question/answer here: http://forums.asp.net/t/2026087.aspx but that did not help. My startup.cs looks like this: public void ConfigureServices(IServiceCollection services) { services.AddMvc(); } public void

问题 I'm having trouble getting sessions to work in my MVC 6 project. I read a great article about this , but I cant get app.UseInMemorySession(); to work in my Startup.cs as described.

问题 Asp.Net Core supports two ways to do global exception handling for a Web Application, implementing IExceptionFilter or by creating custom middleware. Is there any advantage of one over the other? Most references I see are for creating custom middleware. 回答1: The ASP.NET Core docs explains the main differences between these two approaches. It states that exception filters: Handle unhandled exceptions that occur in Razor Page or controller creation, model binding, action filters, or action

问题 There doesn't really seem to be an easy way to make sure the controllers have property injection. A way around it would be to register all controllers individually, which seems to defeat the purpose a bit. The [FromServices] attribute is removed and they specifically mention it should be up to the individual IoC containers to make sure this happens. Am I missing something glaringly obvious? Looked for all available extension methods but didn't find anything, same for issues and the discussion

问题 I'm using the cookie middleware in ASP.NET Core 1.0 without ASP.NET Identity - as described in this article: https://docs.asp.net/en/latest/security/authentication/cookie.html When a user makes certain changes to his/her profile, I need to change some values in the cookie. In such scenarios, this article tells me to call context.ReplacePrincipal() and set the context.ShouldRenew flag to true How exactly do I do that? I think the article is referring to HttpContext. I don't see a

问题 I created an ASP.NET MVC 6 beta 8 application and when I click debug in Visual Studio 2015 I can see IIS Express and the site works properly. But if I try and launch IIS Express from the command line pointing to the right applicationHost.config file I get and error, does something else need to be added?

问题 I have a Shared Project project which contains some content files like JSON, etc. I have a number of ASP.Net core projects and I want to include/share some of these JSON files. Very simple with the "Link to File" option in VS but it's not available in ASP.Net core projects. I've tried playing with the buildOptions/copyToOutput as follows but this does not seem to be working and no error or warning logged in the build process. "copyToOutput": { "include": [ "../Common.Includes/mysettings*.json
