Hi Dinesh,
I made sure that the Branch form doesn't include the fields in the screenshot, i also removed the dependencies between the fields. But I still get the same error for the dependency when trying to delete FinDemo solution.
Here's the Log File:
Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=7.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: The {0}({1}) component cannot be deleted because it is referenced by {2} other components.
