PROBLEM with Deploying WPF App with DotConnect for Oracle

Post by dcuser » Thu 30 Jun 2011 18:49


We are trying to install a WPF application developed using C# and dotConnect for Oracle using clickOnce deployment. We have followed the instruction given in ... ml#project

Still we get the error:

critical errorSchema specified is not valid. Errors:
EntityModel.IVSREntityModel.ssdl(2,86): error 0004: Could not load file or assembly 'Devart.Data.Oracle.Entity, Version=, Culture=neutral, PublicKeyToken=09af7300eec23701' or one of its dependencies. The system cannot find the file specified

We followed the URLs: ... e7e670a204 ... e7e670a204
and updated out project with suggestions from these links. Still the issue persists where we get the error shown above. Please advice on a solution.

We are using VS2010, C#, EF4.0, .NET 4, with dotConnect for Oracle verison 6.30.172

1. Make sure that you deployed Devart.Data.Oracle.Entity.dll v 6.30.172 from the \Program Files\Devart\dotConnect\Oracle\Entity\EF4 folder (not from EF1) with your application.
2. Are Devart.Data.dll v 5.0.272, Devart.Data.Oracle.dll v 6.30.172, and Devart.Data.Oracle.Entity.dll v 6.30.172 available in the same folder where your application (*.exe) resides? For more information, refer to ... yment.html.
3. Have you placed the type definition type="Devart.Data.Oracle.OracleProviderFactory, ..." in one line in the *.config file of your application? This issue was reported in this thread.

If this doesn't help, please post here your entry to the DbProviderFactories section of the *.config file of your application.
