What happened?
My application uses Realm Sync, and accesses the realm by creating a SyncConfiguration and then calling GetInstance() on it. This works fine when the application is online, but if the app is offline, the SyncConfiguration constructor throws the following exception
**System.TypeInitializationException:** 'The type initializer for 'Realms.Helpers.SerializationHelper' threw an exception.' [mono-rt] [ERROR] FATAL UNHANDLED EXCEPTION: System.TypeInitializationException: The type initializer for 'Realms.Helpers.SerializationHelper' threw an exception. ---> MongoDB.Bson.BsonSerializationException: There is already a serializer registered for type DateTimeOffset. [mono-rt] at MongoDB.Bson.Serialization.BsonSerializerRegistry.RegisterSerializer (System.Type type, MongoDB.Bson.Serialization.IBsonSerializer serializer) [0x000a5] in <3323b1fef8254a9a8e9fe351c6349ba3>:0 [mono-rt] at MongoDB.Bson.Serialization.BsonSerializer.RegisterSerializer (System.Type type, MongoDB.Bson.Serialization.IBsonSerializer serializer) [0x00000] in <3323b1fef8254a9a8e9fe351c6349ba3>:0 [mono-rt] at MongoDB.Bson.Serialization.BsonSerializer.RegisterSerializer[T] (MongoDB.Bson.Serialization.IBsonSerializer`1[TValue] serializer) [0x00000] in <3323b1fef8254a9a8e9fe351c6349ba3>:0 [mono-rt] at Realms.Helpers.SerializationHelper..cctor () [0x0002f] in D:\a\realm-dotnet\realm-dotnet\Realm\Realm\Helpers\SerializationHelper.cs:42
Repro steps
1) Sign in a Realm Sync user when online.
2) Turn the phone's internet off and redeploy the app.
3) Get the last logged in user.
4) Create a sync configuration object as follows:
SyncConfiguration config = new SyncConfiguration("PUBLIC", _realmUser);
(This is the stage where the exception is thrown)
