我复制了一个之前的项目并重命名了它。当我成功地重新命名了所有的名称空间，并正确构建了它时，我运行应用程序时遇到了以下错误：
The following errors occurred while attempting to load the app.
- The OwinStartup attribute discovered in assembly 'User Manager Interface' referencing startup type 'User_Manager_Interface.Startup' conflicts with the attribute in assembly 'Service Monitor Web Interface' referencing startup type 'Service_Monitor_Web_Interface.Startup' because they have the same FriendlyName ''. Remove or rename one of the attributes, or reference the desired type directly.
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.
我已经发现，如果我注释掉下面的第一行，那么错误就会消失。
//[assembly: OwinStartupAttribute(typeof(Service_Monitor_Web_Interface.Startup))]
namespace Service_Monitor_Web_Interface
{
public partial class Startup
{
public void Configuration(IAppBuilder app)
{
ConfigureAuth(app);
}
}
}
我将我的解决方案从User_Manager_Interface重命名为Service_Monitor_Web_Interface。
我似乎找不到任何旧名称的位置，但在错误中提到了它。
