Using mongoDB driver versions 2.5+ in Unity3D

[Robert Klausch]

Hello Everyone!

I'm currently using the .NET driver 2.4.4. in a Unity3D project for persisting game states.

These driver version works fine here, but when i'm trying to upgrade the driver to v 2.5.1 or higher i'm getting the following Unity3D compiler error:

"Unloading broken assembly Assets/net45/MongoDB.Driver.Core.dll, this assembly can cause crashes in the runtime"

Unity experts told me, that this is caused by a missing external reference in the project.

So i'm wondering, which external assembly the compiler is looking for MongoDB.Driver.Core.dll from version 2.5.1 on.

Any ideas?

Thanks in advance!

i found a solution for the mentioned problem above by compiling my own driver directly from the source, which actually is containing two more referenced dll's ( in my case this is DnsClient.dll and System.Buffers.dll) which seems to be not getting referenced by the newer driver versions and are not natively referenced into a Unity3D project by itself. On the other hand, they are not included in the driver package for some reasons.

New driver runs perfectly now.
