    Hello, 

     I am getting the following error message with Telerik Data Access:

    configuration 0 DbProviderFactories had no usable entry for invariant name 'FirebirdSql.Data.FirebirdClient' : Unable to find the requested .Net Framework Data Provider.  It may not be installed. (CLR=v4.0.30319 32bit)

     

    The app runs fine otherwise but I would like to make sure that this error is not something serious and would like to understand the root cause of it.

     My backend is FireBird using FireBirdClient 3.0.2.0 (Runtime version v4.0.30319)

     

    Thanks

    Hello Anwar,

    the concepts around DbProviderFactories are explained here .
    In short: That's the standard way of finding ADO drivers at runtime, where machine or app specific configuration can influence the loaded driver or driver version.
