重命名错误的ASP.NET MVC项目

问题描述：

我已经复制了previous项目，并更名为。有一次，我已经成功地重新命名所有的命名空间，并建立正确。我得到了下面的错误，当我跑的应用程序：

I have copied a previous project and renamed it. Once I had successfully renamed all the name spaces and it build correctly. I got the following error when I ran the application:

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.

我想通了，如果我注释掉下面，那么第一行将错误消失。

I have figured out that if I comment out the first line below then the error goes away.

//[assembly: OwinStartupAttribute(typeof(Service_Monitor_Web_Interface.Startup))]
namespace Service_Monitor_Web_Interface
{
public partial class Startup
{
    public void Configuration(IAppBuilder app)
    {
        ConfigureAuth(app);
    }
}
}

我重新命名从User_Manager_Interface到Service_Monitor_Web_Interface解决方案。

I renamed my solution from User_Manager_Interface to Service_Monitor_Web_Interface.

我似乎无法找到旧名称的任何地方，howevel错误它提到它。

I cant seem to find any places with the old name, howevel in the error it mentions it.

答

我有这个问题已经几次，所以我会写下来，我也跟着为自己一个提醒的步骤：

I had this issue a few times already, so I will write down the procedure I follow also as a reminder for myself:

替换所有旧的解决方案的名称与新的。

导航为属性每个项目下，改变的大会名称和默认命名空间字段，以新的解决方案的名称。

转到解决方案文件夹，并用新的解决方案的名称重命名所有项目文件夹。

删除下的所有文件的斌和 OBJ 文件夹。

解决方案将无法加载的项目。删除所有项目并重新添加它们。

重新生成项目。

Replace all of the old solution name with the new one.
Navigate to Properties under each project and change the Assembly Name and Default Namespace fields to new solution name.
Go to solution folder and rename all project folders with the new solution name.
Remove all files under bin and obj folders.
Solution will not be able to load projects. Remove all projects and add them again.
Re-build the project.
