ASP.NET System.Data.EntityClient connection string help

You have to wrap the connection string instide an entity connection string which is in the format of

<add name="Name"
  connectionString="metadata=<Conceptual Model>|<Store Model>|<Mapping Model>;
  provider=<Underlying Connection Provider>;
  provider connection string=&quot;<Underlying ConnectionString>&quot;" 
  providerName="System.Data.EntityClient"/>

Instead of:

<add name="WeddingsDBEntities" 
  connectionString="data Source=<server name>; Initial Catalog=<db name>; User ID=<user ID>; Password=<password>;" 
  providerName="System.Data.EntityClient"/>

Use this:

<add name="WeddingsDBEntities"
  connectionString="metadata=res://*/Models.WeddingsModel.csdl|res://*/Models.WeddingsModel.ssdl|res://*/Models.WeddingsModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data Source=<server name>; Initial Catalog=<db name>; User ID=<user ID>; Password=<password>;MultipleActiveResultSets=True&quot;" 
  providerName="System.Data.EntityClient"/>
