Creating the Data Model

There are two approaches that can be taken in creating the context and entity classes for your application. With the Code-First Approach approach, you can fine-tune your model by writing the classes manually. Alternatively, you can make use of Reverse Engineering (Scaffolding) to generate these classes automatically from your SAP Concur schema.

Perform LINQ Commands in Your Code

After Entity Framework Core is set up and the SAP Concur provider is registered, you can execute LINQ in your code.

using System.Linq;
using MySolutionName.Models;

System.Text.Encoding.RegisterProvider(System.Text.CodePagesEncodingProvider.Instance); // Include this if you would like to use code pages not bundled in .NET Standard.
SAPConcurContext ents = new SAPConcurContext();
var DepartmentsQuery = from Departments in ents.Departments
                   orderby Departments.OfficeId
                   select Departments;
