Hi All,

I am working on the application which is working on Client & Server Model. I am currently migrating the server components to the new Windows Server 2012 R2 from Windows Server 2003.

During this migration, when I am using the WCF services deployed on the server, I am not able to perform any operations related with these services. I am getting following exception.

Unable to find the requested .Net Framework Data Provider.  
It may not be installed. (Fault Detail is equal to An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is: 
System.ArgumentException: Unable to find the requested .Net Framework Data Provider.  
It may not be installed.
   at System.Data.Common.DbProviderFactories.GetFactory(String providerInvariantName)
   at Commons.DAL.AbstractDatabaseConnection`2..ctor(U connectionSettings)
   at ......
   at System.ServiceModel.Dispatcher.SyncMethodInvoker.Invoke(Object instance, Object[] inputs, Object[]& outputs)
   at System.ServiceModel.Dispatcher.DispatchOperationRuntime.InvokeBegin(...).


The WCF Services are supposed to perform CRUD (Create, Read, Update & Delete) operations on Oracle Database.

Please suggest what can I do in order to avoid this error.

Thanks in advance for all your help.

Regards,

Adwait
