MongoDb - Run adminCommand using .NET driver (2.4.4)

Question

In my application I need to ensure that featureCompatibilityVersion is no lower than the required value as part of the integration tests environment setup.

For that I would need to execute getParameter and setFeatureCompatibilityVersion admin commands.

Is there a way to do it using the .NET driver ? Was not able to find a way run using the MongoDB.Driver 2.4.4

The only approach I stumbled across was using the Server.RunAdminCommand method, which appears to be obsolete.

Answer 1

You can use runCommand to get parameter.

var client = new MongoClient();
var database = client.GetDatabase("admin");
BsonDocument parameter = database.RunCommand<BsonDocument>(BsonDocument.Parse("{ getParameter: 1, featureCompatibilityVersion: 1 }"));
