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 Avalara schema.

Perform LINQ Commands in Your Code

After Entity Framework Core is set up and the Avalara 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.
AvalaraContext ents = new AvalaraContext();
var TransactionsQuery = from Transactions in ents.Transactions
                   orderby Transactions.TotalTax
                   select Transactions;
