Mongo DB Atlas database: MongoDB.Driver.Legacy driver is missing

Question

In my C# application I'm not able to access my MongoDB Atlas database.

After creating a database on Atlas, I generate the string to access it and add the following lines in my code:

var client = new MongoClient("mongodb+srv://<username>:<password>@cluster0.5kp6i.mongodb.net/?retryWrites=true&w=majority");
var database = client.GetDatabase("DBTest");

The error is always the same. It seems that the MongoDB.Driver.Legacy driver is missing (username and password are obfuscated):

I suppose there is something wrong with the packages installed. I installed the last version of the Mongo Drivers through the Nuget packages manager:

But I tested also some of the previous version of the same packages without any results. What am I doing wrong?

The targeted framework is the 4.8, could it be the cause? I wouldn't want to change that.

Thank you very much!

Answer 1

After struggling a lot, I found out that a possible solution is to copy the Legacy.dll file into the Program Files folder of the software.

This solution is not feasible for me, so I decided to create customized endpoints on MongoDB Atlas in order to access the database with email and password.
