我一直在做一個VS13 Express和MVC 5的網站。我使用的是使用Owin的ExternalLogin。該項目使用公理生成的本地數據庫。 在本地它的作品完美。 使用WebDeploy部署網站時，將[db] .mdf部署到服務器，但執行登錄時無法找到數據庫。發佈網站（WebPublish）登錄數據庫未找到後
這裏是我的connectionString在web.config中：
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;AttachDbFilename=|DataDirectory|\aspnet-WhyIsItBad2-20131015123340.mdf;Initial Catalog=aspnet-WhyIsItBad2-20131015123340;Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>
而這裏的設置爲WebDeploy
Configuration: Release
File Publish Options: Remove additional files at destination
Databases:
----------
ApplicationDbContext(DefaultConnection)
Data Source=(LocalDB)\v11.0;AttachDbFilename=C:\Users\lissie\Desktop\WhyIsItBad2\WhyIsItBad2\App_Data\aspnet-WhyIsItBad2-20131015123340.mdf;Integrated Security=True;Connect Timeout=30
Use this connection string at runtime(update destination web.config)
Execute Code First Migrations (run on application start)
正如你可以看到我已經遷移激活。 在WebDeploy的預覽步驟中，數據庫出現在數據庫部分。部署不會產生任何錯誤。
但在網站嘗試登錄時，我得到這個錯誤：
Server Error in '/' Application.

對於我理解這個問題是應用程序無法找到數據庫。 我還沒有在谷歌中找到任何東西來幫助我解決這個問題。
