阅读更多关于 Is there a session start equivalent in .Net Core MVC 2.1?

问题 Just started learning ASP.NET 5 / MVC 6 I'm curious about self-hosting such an app outside of IIS - as a Windows service. Should I be using TopShelf for that, like it was the case with OWIN/Katana apps, or does ASP.NET 5 provide some built-in self-hosting (as a service) options via a NuGet package? 回答1: You can use the Kestrel library for self-hosting. Add dependency to the library in the project.json file: "dependencies": { "EntityFramework.Commands": "7.0.0-rc1-final", // Dependencies

问题 I'm writing and ASP.NET Core 1 application, which has a Web API Controller where supplier will post data.

问题 Visual Studio 2015 is not ignoring bower_components folder although it is ignoring node_modules so I don't know what is wrong.

阅读更多关于 ASP .NET Core: CORS headers only for certain static file types

问题 I have an ASP .NET Core self-hosted project. I am serving up content from a static folder (no problem). It serves up images cross-site without issue (CORS header shows up).

If I rename the file to an unknown type (such as JSONX), it gets served with CORS headers, no problem. How can I get this thing to serve everything with a CORS header? I have the following CORS policy set
