How to Access Salesforce Pardot Data Using Entity Framework

Microsoft Entity Framework serves as an object-relational mapping framework for working with data represented as objects. Although Visual Studio offers the ADO.NET Entity Data Model wizard to automatically generate the Entity Model, this model-first approach may present challenges when your data source undergoes changes or when you require greater control over entity operations. In this article, we will delve into the code-first approach for accessing Salesforce Pardot data through the CData ADO.NET Provider, providing you with more flexibility and control.

1. Open Visual Studio and create a new Windows Form Application. This article uses a C# project with .NET 4.5.
2. Run the command 'Install-Package EntityFramework' in the Package Manger Console in Visual Studio to install the latest release of Entity Framework.

3. Modify the App.config file in the project to add a reference to the Salesforce Pardot Entity Framework 6 assembly and the connection string.

   Salesforce Pardot supports connecting through API Version, Username, Password and User Key.

   • ApiVersion: The Salesforce Pardot API version which the provided account can access. Defaults to 4.
   • User: The Username of the Salesforce Pardot account.
   • Password: The Password of the Salesforce Pardot account.
   • UserKey: The unique User Key for the Salesforce Pardot account. This key does not expire.
   • IsDemoAccount (optional): Set to TRUE to connect to a demo account.

   Accessing the Pardot User Key

   The User Key of the current account may be accessed by going to Settings -> My Profile, under the API User Key row.

   <configuration> ... <connectionStrings> <add name="SalesforcePardotContext" connectionString="Offline=False;ApiVersion=4;User=YourUsername;Password=YourPassword;UserKey=YourUserKey;" providerName="System.Data.CData.SalesforcePardot" /> </connectionStrings> <entityFramework> <providers> ... <provider invariantName="System.Data.CData.SalesforcePardot" type="System.Data.CData.SalesforcePardot.SalesforcePardotProviderServices, System.Data.CData.SalesforcePardot.Entities.EF6" /> </providers> <entityFramework> </configuration> </code>
4. Add a reference to System.Data.CData.SalesforcePardot.Entities.EF6.dll, located in the lib -> 4.0 subfolder in the installation directory.
5. Build the project at this point to ensure everything is working correctly. Once that's done, you can start coding using Entity Framework.
6. Add a new .cs file to the project and add a class to it. This will be your database context, and it will extend the DbContext class. In the example, this class is named SalesforcePardotContext. The following code example overrides the OnModelCreating method to make the following changes:
   • Remove PluralizingTableNameConvention from the ModelBuilder Conventions.
   • Remove requests to the MigrationHistory table.
   using System.Data.Entity; using System.Data.Entity.Infrastructure; using System.Data.Entity.ModelConfiguration.Conventions; class SalesforcePardotContext : DbContext { public SalesforcePardotContext() { } protected override void OnModelCreating(DbModelBuilder modelBuilder) { // To remove the requests to the Migration History table Database.SetInitializer<SalesforcePardotContext>(null); // To remove the plural names modelBuilder.Conventions.Remove<PluralizingTableNameConvention>(); } }
7. Create another .cs file and name it after the Salesforce Pardot entity you are retrieving, for example, Prospects. In this file, define both the Entity and the Entity Configuration, which will resemble the example below: using System.Data.Entity.ModelConfiguration; using System.ComponentModel.DataAnnotations.Schema; [System.ComponentModel.DataAnnotations.Schema.Table("Prospects")] public class Prospects { [System.ComponentModel.DataAnnotations.Key] public System.String Id { get; set; } public System.String Email { get; set; } }
8. Now that you have created an entity, add the entity to your context class: public DbSet<Prospects> Prospects { set; get; }
9. With the context and entity finished, you are now ready to query the data in a separate class. For example: SalesforcePardotContext context = new SalesforcePardotContext(); context.Configuration.UseDatabaseNullSemantics = true; var query = from line in context.Prospects select line;
