OWIN - '/'应用程序中的服务器错误
好吧，所以我有这个MVC5网站，使用声明标识。OWIN - '/'应用程序中的服务器错误
OWIN抛出这个讨厌的错误：
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
如果我手动删除的 'bin' 的一切， 'OBJ' 文件夹，网站工作。
问题是，我也在部署中不时发现此错误。
SQL Server很好，工作100％。 这是从OWIN别的东西，造成这种情况。
我记得过去有过这个问题，但我记不清我做了什么来解决它。
下面是完整的堆栈跟踪：

你可以尝试以下...
编辑对ApplicationHost.config通常在C：\ WINDOWS \ SYSTEM32 \ INETSRV \ config并改变setProfileEnvironment为真。
<applicationPoolDefaults managedRuntimeVersion="v4.0">
<processModel identityType="ApplicationPoolIdentity" loadUserProfile="true" setProfileEnvironment="true" />
</applicationPoolDefaults>
谢谢你的回复。我没有这个文件，我从IIS Express（Visual Studio）运行它， –
我发现了这个问题。 Startup.cs中的这3行。
我已经评论他们，现在它相应地工作。
// Configure the db context, user manager and signin manager to use a single instance per request
app.CreatePerOwinContext(ApplicationDbContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
这是一个DI问题，你没有在每次请求后关闭连接池对象吗？ – Neil
