How to get the GP Web Service DLL ?

Posted on by Microsoft Employee

Hi All,

I am new to using the Microsoft Dynamics 2018 web services and I am registering the service and it seems to work but when I try to call:

- I am registering the web service as "http://machine-name:48620/Dynamics/GPService"

DynamicsGP wsDynamicsGP = new DynamicsGP();   it gives me an error stating "Cannot create and instance of the abstract class or interface 'DynamicsGP'"

Any ideas?

I am doing some testing to explore its capabilities atm.

Regards,

Robert.

    Robert,

    Dynamics GP Web Services is driven by a Windows service (Microsoft Dynamics GP Service Host).  In order to utilize that you'll need to have GP Web Services installed (from your GP 2018 installation media), then add a Service Reference to the Native or Legacy endpoint in your Visual Studio project and make your calls against that.

    If you have CustomerSource access you can also download and review for GP Web Services SDK from the following page:

    mbs.microsoft.com/.../MDGP2015_SoftwareDevelopmentKits

    While it states GP 2015 on this download it still applies for newer versions of Dynamics GP.
