Can I change the Type discriminator property in MongoDB?

Question

I am having trouble moving between mongodb and json.net due to polymorphic types. the c# mongodb driver users _t as the discriminator property name and json.net uses $type. I know json.net has this value hardcoded from other research. My question is if anyone knows of a way to rename "_t" to "$type" using the c# mongodb driver?

I believe you can can create a custom discriminator convention and you can add it to each type you wish to modify;

Here's an example of a custom discriminator convention which might help you;
