使用Entity的可视化设计器，我创建了最基本的实体。我想将一些示例数据播种到我创建的数据库中，该数据库在Azure上保存此基本实体的模式。我想在asp.net Web表单中使用这个db，但是当我去播种init数据时，我得到一个SQL超时错误。
我知道当使用实体Database.SetInitializer时，仅在使用上下文时调用种子操作，因此我强制进行初始化。它似乎尝试了我仍然得到超时。我创建了一个基本的控制台应用程序，并编写了一个测试程序，将一些值加载到表中并且工作正常，因此我知道它不是与DB的连接，而是与Seeding有关。
以下是实际错误：
A first chance exception of type 'System.Data.SqlClient.SqlException' occurred in EntityFramework.SqlServer.dll
An exception of type 'System.Data.SqlClient.SqlException' occurred in EntityFramework.SqlServer.dll but was not handled in user code
Additional information: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
