      Summary

      We have a customer running into a projection issue when using the C# driver v2.21.0.

      He's able to workaround this issue either:

      • LinqProvider.V2
      • or LinqProvider.V3 with driver V2.20

      Please provide the version of the driver.

      v2.21.0

      How to Reproduce

      The following projection will return a NULL value using LinqProvider.V3.

      Builders<ClientAccountModel>.Projection.Expression(clientAccount => clientAccount.Bank.Bsb)

      A full working example is attached (MDB_Projection_Bug.txt).
      Two different outputs:

      • V3 Result.jpg: return NULL
      • V2 Result.jpg: return a result
