Hey
I found that a MongoClient is created per each HTTP request. MongoDB strongly advises on a single instance since they don't dispose of resources correctly.
More details here.

Hey, I have been trying to use your code in my application and I found it awesome. but in BaseRepository, Update(TEntity obj) method; when try to use the GetId it gives an error.

error says:

'TEntity' does not contain a definition for 'GetId' and no accessible extension method 'GetId'

Should I implement TEntity as an abstract class? But you don't seem to implement the entity as an abstract class.

Gostei bastante da proposta da solução e gostaria de manter seu repositorio atualizado em relação ao .net core e as bibliotecas utilizadas.
Se puder criar uma branch para que eu faça um pull request com esses updates.

Obrigado.

Hi my friend, I downloaded your code and it's awesome and run good. but before the post-product; when try to dispose the class. appare a error.
