    Hi,

    I have created a Coded UI Test project with the following settings:
    NuGet Packages Installed:
    EntityFramework 6.0.0 
    Oracle.ManagedDataAccess.EntityFrameWork 12.1.2400
    Oracle.ManagedDataAccess 12.1.2400

    Target Framework:.Net Framework 4.5.2

    When trying to access the oracle database through Entity Eramework 6.0.0, I get the exception below:

    Result Message:
    Test method ExcelDBImplementation.CodedUITest1.CodedUITestOracleEntityFramework threw exception: 
    System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.TypeInitializationException: The type initializer for 'System.Data.Entity.SqlServer.SqlProviderServices' threw an exception. ---> System.TypeLoadException: Could not load type 'System.Data.Entity.Infrastructure.TableExistenceChecker' from assembly 'EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

    However, when running a console application project or a unit test project with the same settings, it runs sucessfully. Is there any difference in the Coded UI Test project that causes this difference in behaviour?

    Automated tests that drive your application through its user interface (UI) are known as coded UI tests (CUITs).

    Hi abubakar.semasaba,

    Please re-install the entity framework Package and upgrade to the lasted version and check if it works. please refer to the following steps.

    1. Open your solution and go to Tools -> Nuget Package Manager -> Package Manager Console

    2. Select the project that uses EF and is having the problem

    3. Type Uninstall-package EntityFramework

    4. You should be prompted to restart Visual Studio so close and reopen VS and your solution

    5. Open Package Manager Console with Tools...Library Package Manager...Package Manager Console

    6. Type Install-package EntityFramework

    Best regards,

    Cole Wu

    Hi abubakar.semasaba,

    Since our policy, we could not install oracle on my machine, I could not reproduce your issue on my side. I would suggest that you could post your issue on oracle for suitable support.

    https://community.oracle.com/community/database/developer-tools/windows_and_.net/oracle_developer_tools_for_visual_studio

    Thanks for your understanding.

    Best regards,

    Cole

    Hi Cole,

    There has been no response from the forum since I last posted. And the problem is still persisting.
