Aspire.Hosting.DocumentDB

A .NET Aspire hosting integration for DocumentDB, the open-source MongoDB-compatible document database built on PostgreSQL.

This package lets you add a DocumentDB container to your Aspire AppHost with a single line of code. Connection strings, credentials, TLS, and container lifecycle are managed automatically.

Quick start

Prerequisites

• .NET 10 SDK or later
• .NET Aspire workload: dotnet workload install aspire
• Docker (DocumentDB runs as a Linux container)

Install the package

In your Aspire AppHost project:

dotnet add package Aspire.Hosting.DocumentDB

Add DocumentDB to your AppHost

var builder = DistributedApplication.CreateBuilder(args);

var db = builder.AddDocumentDB("documentdb")
                .AddDatabase("mydb");

builder.AddProject<Projects.MyService>("myservice")
       .WithReference(db)
       .WaitFor(db);

builder.Build().Run();

Use MongoDB client in your service

In your service project, install and register the MongoDB driver:

dotnet add package Aspire.MongoDB.Driver

builder.AddMongoDBClient("mydb");

Then inject IMongoClient wherever you need it. The connection string is resolved automatically.

About DocumentDB

DocumentDB is an open-source document database that provides MongoDB compatibility on top of PostgreSQL. It supports:

• Full MongoDB CRUD API via the MongoDB wire protocol
• BSON document storage
• Rich query support including aggregation pipelines
• Full-text, geospatial, and vector search
• SCRAM-SHA-256 authentication with TLS

The Aspire integration runs the documentdb-local container image, which bundles the DocumentDB gateway and PostgreSQL backend in a single container.
