Creating the Data Model

There are two approaches to creating the context and entity classes for your application. Using the Code-First Approach approach, you can fine-tune your model by writing the classes manually. Alternatively, you can use Reverse Engineering (Scaffolding) to generate these classes automatically from your FHIR schema.

Perform LINQ Commands in Your Code

After EF Core is set up and the FHIR provider is registered, you can begin querying your data with LINQ:

using System.Linq;
using MySolutionName.Models;

FHIRContext ents = new FHIRContext();
var PatientQuery = from Patient in ents.Patient
                   orderby Patient.[address-city]
                   select Patient;
