    Hi everyone,
    I am new in telerik ORM and trying to generate my Data Access Layer (DAL), Data Services, Silverlight UI with Telerik ORM and Data Services Wizard. I was able to generate all the necessary classes for DAL. Then build the DAL successfully. After that I tried to generate WCF Data Services Layer and Silverlight UI layer with Data Services Wizard. But I am now stuck with the internal exception of DSW as shown in the attached image, stated nothing about the real problem. Before starting the DSW I have enabled the web application project for Telerik ORM. 

    I have tried to check the blog posts linked in DSW hompage in telerik site. Following is one of them.,guid,9da617ab-f441-454e-b73e-ed2fba8113c3.aspx

    But unfortunately these posts were written in december 2009 and the explanation does not match with the current version of DSW.

    I am using Visual Studio 2008 and Silverlight 3. If any one can help me to generate Data Services classes and Silverlight UI components with DSW then it would be great for me.

    Hello Hassanur Rahman,

    I think you might have a problem while connecting to the database. The wizard is trying to connect to the database to extract the entities ( as I can see on the attached image ) but it failed, so please double check your connection string as well as whether you have the same connection string name in:
    1- app.config
    2- ObjectScopeProvider at
        a- AdjustForDynamicLoad function.
        b- Database function.

    Then try again, the problem should be solved.
    If the error remains, please let me have a look at you code.
    Best wishes,
