I generated a linq class to access our oracle server. When i start using this class in my source code the following error raises:

Code: Select all

System.IO.FileLoadException: Could not load file or assembly 'Devart.Data.Oracle, Version=5.0.10.0, Culture=neutral, PublicKeyToken=09af7300eec23701' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
   at Devart.Data.Oracle.Linq.Provider.OracleDataProvider.CreateConnection()

   at Devart.Data.Linq.DataContext.a(Object A_0, MappingSource A_1)
   at Devart.Data.Linq.DataContext..ctor(String connectionString, MappingSource mapping)

The version of the installed Devart.Data.Oracle Assembly is 5.0.12.0. I cannot find any reference to 5.0.10.0 in my project.

Probably, you were using the Devart.Data.Oracle assembly version 5.0.10.0 in your project previously. Just set the "Specific version" property for this assembly to "False" or remove the reference to the assembly of old version and add the new one (to the 5.0.12.0 version).

I updated from Version 4.6 to 5 yesterday. Everything went fine until I added Devart.Data.Linq and Devart.Data.Oracle.Linq to migrate the data access.

Please replace the assembly Devart.Data.Oracle.Linq.dll from your project local folder with the new version (from %Program Files%\Devart\dotConnect\Linq\Devart.Data.Oracle.Linq.dll), if any.

It works now. I had to add the following to "web.config"

Code: Select all

This didn't work. I never had 5.0.10.0.
