EPiServer 7: There is already an open DataReader associated with this Command which must be closed first.

I ran into the following error on an EPiServer 7 Preview site today:

There is already an open DataReader associated with this Command which must be closed first.”

The problem is that EPiServer 7 requires that the MultipleActiveResultSets is set to true in the connection string.

 

ConnectionStrings.config:

<connectionStrings>
  <clear />
  <add name="EPiServerDB" 
       connectionString="Data Source=(local)\SQLEXPRESS;
         Initial Catalog=epi;
         Integrated Security=False;
         User ID=user;
         Password=pwd;
         MultipleActiveResultSets=True" 
       providerName="System.Data.SqlClient" />
</connectionStrings>
