[BUG] Outdated MongoDB.Driver.Core dependency in Elastic.Apm.MongoDb

[th3ragex]

The lastest MongoDB Diagnostic listener has a dependency to "MongoDB.Driver.Core" Version="2.19.0"

apm-agent-dotnet/src/instrumentations/Elastic.Apm.MongoDb/Elastic.Apm.MongoDb.csproj

Line 29 in 2d1a0db

<PackageReference Include="MongoDB.Driver.Core" Version="2.19.0" />

I have compile issues in a project with a dependency to MongoDB.Driver Version 2.28.0 with "MongoDB.Driver.Core" Version="2.28.0" as transient dependency and "Elastic.Apm.MongoDb" Version="1.28.1".

error CS0012: The type 'IEventSubscriber' is defined in an assembly that is not referenced. You must add a reference to assembly 'MongoDB.Driver.Core, Version=2.19.0.0, Culture=neutral, PublicKeyToken=null'.
error CS1503: Argument 1: cannot convert from 'Elastic.Apm.MongoDb.MongoDbEventSubscriber' to 'MongoDB.Driver.Core.Events.IEventSubscriber'

in:

var clientSettings = MongoClientSettings.FromConnectionString(settings.ConnectionString);

// https://www.elastic.co/guide/en/apm/agent/dotnet/1.x/setup-mongo-db.html
clientSettings.ClusterConfigurator = builder => builder.Subscribe(new MongoDbEventSubscriber());

The last update was done on year ago: #2030

1. Did the dependabot / renovatebot break?
2. Please update the MongoDB.Driver.Core dependency.

I'm all for updating deps in general,

Need to dive in and understand what the breaking change between 2.19.0 and 2.28.0 is though.

Oh yeah thanks for bringing this to our attention @th3ragex! 😸

Hi @Mpdreamz

We are facing the same issue and another one:
CS0012 The type 'IMongoClient' is defined in an assembly that is not referenced. You must add a reference to assembly 'MongoDB.Driver, Version=2.22.0.0, Culture=neutral, PublicKeyToken=null'

    services.AddMongoDb(
        MongoClientSettings.FromUrl(mongoUrl),
        name: "MongoDBHealthCheck",
        timeout: options.HealthcheckTimeout);

The behaviour is very weird. When we were having the version to 2.22.0 all was working fine, but when we are trying to update to 2.28.0 we get the same error as @th3ragex with the one mentioned

Looks like MongoDB 1.28.0 introduced a breaking change:

Opened #2419 to address this

There's a similar issue occurring now when updating the MongoDB.Driver package to v3.0.0. Looks like Elastic.Apm.MongoDb will require this update from v2.28.0 to v3.0.0

Opened #2419 to address this
