Thank you for the post. I have couple questions that I wish if you could answer please:

1) Does the Entity Framework support Multi Databases? For Example MySql And Oracle or any OLEDB provider! and is they supported by default or I need to write that?

2) Is there away to Separate the Context Class from the Entity Types, I mean having the context classes on some namespace while the all other Entity Classes on another namespace using the Designer.

3) Where can I find downloadable Documentations for The Entity Framework, or MSDN update for the current SP1

I'm sure there will be few other things as I move on.

Hello.

Thanks for great product. But I have a question. Will RTM EF work on hosting with .net 3.5 installed. Without Sp1?

@Muhammad Mosa:

1) The entity framework is designed to build on the ado.net provider model and work with multiple databases. What ships out of the box with .net 3.5 sp1 is support for SQL Server and SQL CE. A number of third parties are working on providers for other databases like MySQL, Oracle, DB2, etc. and we look forward to releases of these over the next few months -- other posts on this blog can give more details. OLEDB in general is not supported because an EF provider needs to know more about the syntax of the backend database than it can learn from an arbitrary OLEDB connection, but of course a provider for a particular backend could use OLEDB under the covers, but it would just have to be specific to a backend.

2) The code generation which the system produces by default will not generate the context separately from the entity classes in v1. This is something that we are looking to enable in v2, but for now you can either write the classes yourself rather than using codegen or make your own codegen which would do this. The framework runtime does not require that you use the classes which our codegen will produce.

3) Right now the documentation is available online. I don't konw what the schedule is for a downloadable update. Sorry.

@AlfeG:

Sorry, but no, the entityframework will not work in an environment which only has .net 3.5 installed. You must have .net 3.5 sp1 installed for it to work.

Does it possible to create dynamic conditions.

Somethink like this:

<cs:Condition cs:ColumnName=”Discontinued” cs:Value="SomeNamespace.SomeClass.SomeMethod”/>

instead of this:

<cs:Condition cs:ColumnName=”Discontinued” cs:Value=”0”/>

If not, will be it possible in future versions?

I am still using the last beta from Entity framework and the Entity Framework tools from Dec CTP, right now for project constrains, I have to delay the update for a couple of weeks, my problem is with the Designer, I can no longer update the model from the Database, the screen that was showed to update the model is no showed.

Also I try to create a new model and I cannot create a new model anymore, as I said, I have not installed the SP1, what could be wrong?

Regards,

Pedro.
