Missing Method Exception : Method not found: 'System.TimeSpan, MongoDB.Driver.Core.Configuration.ServerSettings.get_DefaultHeartbeatInterval()'.

[Taz Uddin]

I'm getting this 'Missing method exception' which I have no idea of. Anybody have any ?

Which version of the driver are you using?

Can you provide a stack trace?

Perhaps you have multiple projects that use the MongoDB driver and the projects are not all using the same version of the driver?

One thing you could try is to drop all references to the MongoDB driver and add them back making sure they are all referring to the same version.
