Will there be support for enumerations in POCO?

Hi,

Why does not EF use multiple result sets in its final SQL query ? Wouldn't that be more efficient?

Thanks.

In regards to @Jinal's comment above, on the EF supporting multiple result sets, do you have some sample code using the Translate() method you mentioned? Maybe website describing the steps?

I just did my first EF, .net 3.5 RIA services app using Silverlight and had to do all these workarounds to handle multiple results sets in the EF.

The complex type is a great addition though just looking for code to handle the multiple result sets.

Thanks

Sorry if this isn't the correct place to post a question! I've started looking at using EF 4 as an alternative to LINQ to SQL. One thing I've noticed, when using Include() to load extra data with an entity, EF always translates this to a left outer join when it could often use an inner join, i.e. when the ID column is not nullable and there is a foreign key setup. Is there a way to get it to use inner joins instead? Or does it not actually make a difference performance wise?

@Michael

The SQL CE Provider currently doesn't include the DDL support required for CreateDatabase(), our teams are currently working on this and hope to have support in the next release of the SQL CE Provider.

I got {"Unable to determine the provider name for connection of type 'System.Data.SqlServerCe.SqlCeConnection'."}

in code

SqlCeConnection scc = new SqlCeConnection(sqlCeConnnectionStr);

MyContext oc = ContextBuilder.CreateDefaultContext<MyContext>(new SqlCeConnection(sce.LocalConnectionString));

oc.CreateDatabase();

MyContext from samples in this blog.

Connection string is "Data Source=./My.sdf;Password=password;Encrypt=true;File Mode=Exclusive;"

Hi,

Is there a way to get notified about the exceptions handled within stored procedures?

Thanks Danny,

I've been trying to use SQLCE with Code Only. I'm wondering if this is possible. The ContextBuilder seems to be choking on the SQLCE Connection. Pls. advise.
