Trying to access MongoDbSet<> - Object reference not set to an instance of an object.

[leftbrasil]

Got this error using both, main and fluent-mapping branches. Could you give me a tip on what's happening?

Declared my context:

public class MensagensDbContext : MongoDbContext
    {
        public MensagensDbContext(IMongoDbConnection connection) : base(connection)
        {
        }
        public MongoDbSet<Mensagem> Mensagens { get; set; }
        public MongoDbSet<MediaMessage> MediaMessages { get; set; }
    }

Dependency injection:

builder.Services.AddTransient<IMongoDbConnection>(
    s => MongoDbConnection.FromConnectionString(mongocon)
    );
builder.Services.AddTransient<MensagensDbContext>();

In this case, providerType.GetMethod("Translate") returns null and providerType.GetMethods() doesn't show any "Translate" method

[leftbrasil]

The problem is the MongoDb.Driver. I believe that the version 2.19.0 renamed the "Translate" method to "CreateQuery". Rolled back to version 2.18.0 of the driver and it works perfectly fine.

Hey @leftbrasil - thanks for raising this issue! Yep, that looks like an integration bug with MongoFramework and the MongoDB driver. I'm planning to do another release soon with some major changes, I'll try and get in a fix for driver 2.19.0.

[Turnerj]

I've released v0.28.0 of MongoFramework which addresses the problem with the 2.19.0 version of the driver.
