c# - OWIN 启动类丢失

Question

我收到此错误是因为我的项目无法找到 OWIN 启动类的引用。我什至通过 Nuget 安装了所有 OWIN 引用包，但仍然遇到同样的问题。我正在使用 Visual Studio 2012 和 MVC4。

尝试加载应用程序时出现以下错误。

• No assembly found containing an OwinStartupAttribute.
• No assembly found containing a Startup or [AssemblyName].Startup class. To disable OWIN startup discovery, add the appSetting owin:AutomaticAppStartup with a value of "false" in your web.config. To specify the OWIN startup Assembly, Class, or Method, add the appSetting owin:AppStartup with the fully qualified startup class or configuration method name in your web.config.

Answer 1

Create One Class With Name Startup 这将帮助你..

public class Startup
{
   public void Configuration(IAppBuilder app)
   {
      app.MapSignalR();
   }
}
