我正在使用Visual Studio 2013更新4.我创建了一个默认的MVC5 ASP.NET Web应用程序，经过测试，运行，一切正常。我选择了个人帐户授权（默认），并且没有任何更改。
然后我尝试在同一台PC的IIS服务器上本地发布，但是我在连接数据库时遇到了问题。
我安装了SQL Server 2012 Express，从那以后，什么都没有了。 我得到的错误是(exactly as here)：
Could not load file or assembly 'Microsoft.Owin, Version=2.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.
尝试通过安装2.1.0 nuget包解决问题似乎可以部分解决问题，因为稍后在应用程序运行中我收到有关webgrease的错误，但这里没有版本不匹配。
项目是否有可能从其他地方获取web.config？如何解决这个问题？我不想与owin 2.1.0一起运行，因为最新版本是3.0.1。为什么安装SQL后它不起作用？卸载SQL并重新安装Visual Studio无法解决问题。
这是web.config片段（不工作）：

我之前遇到过这样的问题。正确的安装顺序是SQL Server 2012 THEN Visual Studio 2013.
这是因为SQL Server已经使用一些Visual Studio组件构建，这些组件覆盖Visual Studio 2013组件导致不正确的行为/问题。
Visual Studio 2010,2008和SQL Server 2008也是如此.SQL Server应该始终是第一个。
