實體框架在使用SQL Express時不會創建我的數據庫,但如果我使用SQL Server CE,則它工作正常。實體框架在使用sqlserver時不創建數據庫
我一直試圖弄清楚這幾天,但它可能是我對ASP.NET和MVC的經驗不足。
ConnectionStrings:
<connectionStrings>
<!--
<add name="CRM"
connectionString="data source=|DataDirectory|CRM.sdf"
providerName="System.Data.SqlServerCe.4.0" />-->
<add name="CRM"
connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\CRM.mdf;User Instance=true"
providerName="System.Data.SqlClient" />
<add name="ApplicationServices"
connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true"
providerName="System.Data.SqlClient" />
</connectionStrings>
堆棧跟蹤:

哇!這工作!謝謝!我很驚訝,因爲我沒有看到任何包括成員資格連接字符串的例子。十分感謝你的幫助! – user1658921
有關其他信息,雖然您提供了一個mdf文件,但SQLEXPRESS仍然需要知道應該將哪個數據庫視爲該文件(爲了這個和將來的參考)。 –
