I am trying to perform a bulkwrite with c# https://mongodb.github.io/mongo-csharp-driver/2.7/reference/driver/crud/writing/#bulk-writes - I could have a list of documents from 70-80K....

The first argument passed to
UpdateOneModel is the filter. The filter tells MongoDB which document you want to update. You pass
new BsonDocument("_id", 1), which tells MongoDB you want to update the document with an
_id is a special field in MongoDB documents:
The field name _id is reserved for use as a primary key; its value must be unique in the collection, is immutable, and may be of any type other than an array. If the _id contains subfields, the subfield names cannot begin with a ($) symbol
_id is immutable, meaning it cannot be changed. This is an issue because the data you are passing to
$set contains an
_id field that is not
Instead, in the filter document you should be passing the
_id of the document you are trying to insert.
I'm trying to retrieve a list of objects from my MongoDB Database. I have to use a BsonDocument to store additional dynamic data on the record, but when I try to return a list to the browser using minimal API I get the following error....

I am trying to access the Save() method detailed in the driver documentation, but there seems to be no definition at all of the method when I call the function from an
IMongoCollection, and the class
MongoCollection is not found or recognized by the IDE.
The reason I am trying to call
Save() instead of
Update(), is that I want it to be by
_id, I am trying to implement a generic
IMongoRepository() that would just update a document within a collection without needing any extra information.

Save (as well as MongoCollection class itself) is deprecated method in the Legacy driver, the current driver doesn't have this functionality, see here
I have a service that needs to watch a collection on a Mongo DB to create changes in the system. I have managed to establish a connection to a replica set using the C# driver and I'm using the following code to test the change stream....

We need to load mongodb c# assembly at runtime.

This is because the class implements the
Description property explicitly. Thus your code should look like this in order to fix it. That is, you need to explicitly cast to the correct interface.
NB. The question is not about what null reference protector operator (X?.Y) means. I'm aware the title is a bit cryptical but I haven't figure out a better way to formulate it. Sorry.

This is fun. If you whittle it down to a minimal reproducer, you get this:
I have a 3 projects (.sln) that are their own project plus a secondary project that has the MongoDB code in it.
On the same computer with the 3 visual studio project open calling the same methods only 1 of them work the other all throw and error. Since it's the same line of code it mean there is a setting in the main project that mongo doesn't seems to like. Any idea what this might be.
here's the method in question in the shared project for mongo:...

The issue is as of the time of writing this the
MongoDB.Driver v2.11.0 is bugged. There is some sort of incompatibility in the library it's using that if you downgrade to
MongoDB.Driver v2.10.4 it works perfectly.
Edit : It doesn't work "perfectly" as i described. Actually one major problem is that i cannot use allowDiskUse on any find operation anymore with 2.10.4. It doesn't seem to accept it or work at all.

As said in the comments by the others, this is technically not a GUID. Meanwhile, you can redo the bitwise operator this way:
Is there a way to disable completely (for all classes) the discriminator ("_t") fields from being added to the bson documents? I am referring to: mongo-csharp-driver/polymorphism...
ANSWERAnswered 2020-Aug-27 at 16:00
One option is using Newtonsoft bson serializer (Newtonsoft.Json.Bson) which gives a lot of serialization options.
It isn't efficient since you need to write the bson to a stream and then read it from there with MongoDb reader but it provides lots of customization option. Example code:
So I'm building an ASP.NET-Core API connecting to a mongoDB instance. I was reading through the official Microsoft tutorial regarding this topic and came across the linked code sample.
Basically they instantiate a
BookService and create a new instance of
MongoClient in the scope of the constructor.
