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 Avalara schema.

Perform LINQ Commands in Your Code

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

using System.Linq;
using MySolutionName.Models;

AvalaraContext ents = new AvalaraContext();
var TransactionsQuery = from Transactions in ents.Transactions
                   orderby Transactions.TotalTax
                   select Transactions;
