c# - 安装客户站点umbraco 7 站点后首次运行时出现 owin 错误

Question

我在 7.3 umbraco 版本上遇到这个错误:

The following errors occurred while attempting to load the app. - The OwinStartupAttribute.FriendlyName value 'UmbracoDefaultOwinStartup' does not match the given value '' in Assembly 'umbraco, Version=1.0.5750.18164, Culture=neutral, PublicKeyToken=null'. - 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.

有什么想法吗？我什至从 bin 文件夹中删除了 owin.dll 并从解决方案中删除了引用，也添加到 web.config <add key="owin:AutomaticAppStartup" value="false" />仍然得到同样的错误？

谢谢

如果您插入以下 web.config appSettings，它应该会启动:

<add key="owin:AutomaticAppStartup" value="true" />
<add key="owin:appStartup" value="UmbracoDefaultOwinStartup" />

我在升级 7.2.8 -> 7.4.1 后收到此错误。执行上述操作后，Umbraco 声称找不到 System.Object。通过将以下内容添加到程序集部分解决了这个问题:

<add assembly="System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

此外；如果您收到任何不匹配的依赖项(我收到一条消息，“umbraco”试图使用 Microsoft.Owin 2.1.0，尽管最新的 Umbraco NuGet 随 3.0.1.0 一起发布)，您可能需要将以下内容添加到 assemblyBinding 部分:

<dependentAssembly>
   <assemblyIdentity name="Microsoft.Owin" publicKeyToken="31bf3856ad364e35" culture="neutral" />
   <bindingRedirect oldVersion="0.0.0.0-3.0.1.0" newVersion="3.0.1.0" />
</dependentAssembly>
