Using WCF with real time XML exchange

Hi everyone,

I'm new to WCF I would like to understand the approach or workaround with the requirement below.

My company has multiple applications in .Net window form. All the are done by vendor where code change is not allowed. The application will generate the XML files in FTP Folder where current exchange by using ETL.

ETL unable to archive real time file exchange. Could I use the WCF to archive the exchange data requirement in real time? The data will be load from one end in XML and WCF service shall transform the data that fit the data format for another end by transmitting the transformed file in XML to receiver's folder. The receiver will pick up the XML thereafter to its database.

Thanks for any advice
