Can't get going with ORM

[Tom]

 

I must have missed something basic. Using either  Oracle or SQL server 2008 R2, win 7 or Server 2008 I get the same errors that the libraries aren't found/recognised.

I'm trying to build a Silverlight App (4) in VS 2010 with ORM to handle the data bits with errors that iunclude

Error 6 Type 'OpenAccessContext' is not defined. C:\inetpub\wwwroot\ORM01\ORM01\EntityDiagrams.vb 30 13 ORM01
Error 7 Type 'BackendConfiguration' is not defined. C:\inetpub\wwwroot\ORM01\ORM01\EntityDiagrams.vb 33 29 ORM01
Error 13 'GetAll' is not a member of 'ORM01.BadgerTrackEntityDiagrams'. C:\inetpub\wwwroot\ORM01\ORM01\EntityDiagrams.vb 59 12 ORM01

Maybe SL 4 is not yet supported.

The bits in yellow are my comments

 

Please Help!

Hello Tom,

What I suspect is required to get your project working is update the references to the Telerik OpenAccess assemblies. You can right-click your project in the solution explorer and select the Upgrade References option. You will be prompted to reload your projects. If the problem is still there, which should not be the case, you can try and manually remove and add again the references in the solution explorer – right-click References, then select Add Reference and locate the assemblies in the .NET tab. The assembly where the OpenAccessContext class is located is Telerik.OpenAccess.35.Extensions, so please make sure your project is referencing it.

I hope this helps. Do not hesitate to contact us if the problem persists.

Thanks for coming back,


I am afraid neither worked: I had previously updated the references. The error I get is that Telerik.OpenAccess.35.Extensions.dll was not built against the Silverlight Runtime. -I am using 4, which I think is where the problem lies. Open Access 40 doesn't work either by the way.

Does ORM work with SL4?

Hi Tom,

Silverlight 4.0 is supported with OpenAccess. The setup process, however, is a bit different from adding a domain model in a common .NET project. Here is a blog post which explains the basics of the integration between Silverlight projects and OpenAccess. Please, follow the steps described there and see if you can get your solution working. Contact us again to tell us whether you have already tried the tutorial or you experience the same or other hurdles.

Kind regards,

Thank You,

I am running now. The mistake I made was to try to add the Domain Service model to the SL project instead of the server one.
