While I do go back to Turbo Pascal days, I've worked exclusively in C# since .NET 1.0 came out.

So, I'm more used to C# server back ends.

I take it given the strong JSON support, etc., that tying an EWB 2 app to an C# WebAPI/REST/ODATA backend is straightforward?

Is there a Help/technical article on best practices on this, or sample code?

I'm almost tempted to invest in a copy of Embarcadero RAD Studio, but my Object Pascal coding skills are rusty, and I'd rather leverage C# in the backend.

Stick with C#. EWB is "just" a normal SPA tool, so you can access data
in whatever way you want just like any other AJAX system. I did an
application that used the TServerRequest object to talk to a normal C#
REST service. You can access the data however you want, XML, JSON or
custom. Version 2 has JSON enhancements, but it was possible before.

Boris,

It's really just a matter of handling the dataset requests and being able to
respond with the correct JSON, as well as consuming transaction operations.

You can find a complete reference here:

A good way to see what's going on is to simply load up this example
application in the browser of your choice, and turn on the network sniffing
functionality in the browser's developer tools:

Then just refresh the application and try performing a transaction.

And, if you have any questions while implementing the interface, you can
always ask here.

Thanks for both replies.

The data set functionality is well documented and clear enough.

It was more WebAPI calls I guess that I wondered about, things like (in C#)

public UserPermissions GetUserPermissions();

public DateTime GetRevisedDesireByDate( GetReviseDesireByDateRequest request );

etc.
