Repository pattern implementation of MongoDB collections using LINQ with optional Dependency Tracking in .NET Standard 2.0.

Usage

Connection

Connection string should be provided by using Connection class. Inject this class in the following manner if you are using DI:

services.AddTransient(x => new Connection(Configuration.GetConnectionString("DefaultConnection")));

Settings

1. Global collection settings can be applied by using Settings.Configure<T> where T is collection model implementing IDbModel. This method accepts:

   • Connection (for connection string)
   • Expire After (for ExpiryAfterSeconds index)
   • Create Collection Options ()

Use this method with a specific collection model, make sure this method is called once for each application run.

2. If you intend to use Dependency Tracking, you can specify commands to not track by setting the Settings.NotTrackedCommands, by default the following commands are not not tracked:

   • isMaster
   • buildInfo
   • getLastError
   • saslStart
   • saslContinue
   • listIndexes

Collections

Create a collection model implementing IDbModel interface for use in repository. The name of this model will be used as collection name in MongoDB. For example:

public class Activity : IDbModel
{
    public ObjectId Id { get; set; }
    public bool Deleted { get; set; }
    public DateTime CreationDate { get; set; }
    public DateTime? UpdationDate { get; set; }
    public string Name { get; set; }
}

Dependency Tracking

To use dependency tracking implement the IDependencyTracker interface to meet your needs. For example:

public class DependencyTracker : IDependencyTracker
{
	public void Dependency(string name, string description, bool success, TimeSpan duration)
    {
    	Console.WriteLine($"{name}-{description}-{success}-{duration}");
    }
}
