      Windows Server 2012 R2 64-bit, MongoDB 3.6, .NET 4.5

      I just updated our development MongoDB instance to MongoDB 3.6 using the C# Driver 2.5. When setting the new option "RetryWrites" in MongoClientSettings to true, I get the error message listed below when trying to insert a new document.

      The feature compatibility version is set to 3.6, although this should probably work with older MongoDB versions as well. The database is running on the same server as the code using the C# driver, the database is configured as a standalone instance.

      Setting the option "RetryWrites" to false allows the write operation to succeed, so this issue seems to be caused by enabling retries. I would expect this option to work for standalone installations as well as for replica set installations. 

      Command insert failed: Transaction numbers are only allowed on a replica set member or mongos.
