Introduction to Marten

Marten is a .NET library that offers streamlined database interaction with PostgreSQL, supporting multiple document types and ACID-compliant transactions.

Step 1: Setting Up Your Environment

Before diving into Marten, ensure your development environment is prepared. This includes having a PostgreSQL server and a .NET development environment such as Visual Studio installed.

Step 2: Installing Marten

To begin using Marten, you need to install the Marten package via NuGet. Use the following command in your package manager console:

Install-Package Marten

Step 3: Configuring Your Database

After installation, configure Marten to connect to your PostgreSQL database. Inside your Startup.cs file, add the following configuration:

services.AddMarten("your_connection_string");

Replace "your_connection_string" with the actual connection string to your PostgreSQL database.

Step 4: Defining Your Document Store

Define your document store, which will manage your documents. Create a new class to represent your document model, for example:

public class User { public Guid Id { get; set; } public string Name { get; set; } }

Next, initialize the store with the following:

var store = DocumentStore.For("your_connection_string");

Step 5: Performing CRUD Operations

With your setup complete, you can perform standard CRUD operations. For instance, to add a new document:

using (var session = store.LightweightSession()) { var user = new User { Id = Guid.NewGuid(), Name = "John Doe" }; session.Store(user); session.SaveChanges(); }

You can retrieve, update, and delete documents in a similar manner.

Conclusion

Marten simplifies database interactions, making it easier for .NET developers to utilize PostgreSQL efficiently. By following these steps, developers can integrate Marten into their projects, enabling robust and scalable database management.
