Devart Forums

I have installed VS 2008 SP1 (not beta) and now have a problem with the EDM designer. I wonder if anyone knows away around it?

The MsSQL driver works, so I've narrowed it down to the 4.70.31 Devart driver. I probably guess MS made a breaking change between beta and release.

To reproduce try to update and existing EDM or create a new EDM. The error should be thrown in the reverse engineering database wizard section.

The error I get is

An error occured while connecting to the database. The database might be unavailable. An exception of type 'System.Data.EntityCommandComplilationException' occurred. The error message is: 'An error occurred while preparing the command definition. See the inner exception for details. The inner exception caught was of type 'System.MethodAccessException', with this error message: 'System.Data.Common.CommandTrees.Db.CommandTree.Validate()'.'.

Ok I've found the problem...

Any chance someone from Devart could post a when the next build supporting sp1 will be out?

New, compatible with the Visual Studio 2008 SP1 RTM builds will be available in several days.

Once again Andrey thanks for the update. You guys ROCK!

Please note that current build (4.80) still does not support VS2008 SP1 RTM. The build with its support is coming soon.

I just downloaded the 4.80.32 trial in hopes of correcting this exception, but I am still getting it. I can connect to my DB in server explorer, etc., but when I try to create an entity model from the db, I get the System.MethodAccessException described in this thread.

I am using the recently release VStudio 2008 SP1. I see the prior note in this forum saying SP1 support is "coming soon." Can you be any more specific? I am working on a proof-of-concept for a client that must be completed within a matter of days.

Please advise ASAP. Entity Framework support is my primary reason for considering this driver. If my proof-of-concept works out, client is almost certain to purchase this driver.

Hi adambsn,

The EDM drive support is in beta. You probably shouldn't be using it production. Though I too have broken this rule!

From previous experience I'd say they'll release the updated drive in around a week or two.

Probably your only choice would be to roll back to vs 2008 sp1-beta. I mean if this is very important, then the roll back is the way to go. Ah the joy of VS and it's very quick install process

Pleb

Is there any way to get access to the beta version to do some evaluation with EDM? I'm on my, well, about fourth "proof-of-concept" code-base for a project that's way behind. (I get the above error message as well. VS2008 SP1)

Thanks

MyDirect .NET version 4.85 is released. It supports Visual Studio 2008 Service Pack 1.

Thanks Shalex, though your PR people beat your too it. I got an email yesterday saying it was available...

Anyway thank you as it seems to be working very well.
