+# Worth Knowing
+
+This package sets the `MongoDefaults.GuidRepresentation` to `MongoDB.Bson.GuidRepresentation.Standard` by default, instead of the default driver setting of `MongoDB.Bson.GuidRepresentation.CSharpLegacy`. This can cause issues if you have been using the driver on an existing application previously or if you are using CosmosDB.
+
+You can override this behaviour to enforce legacy behaviour in your app Startup routine like so :
+
+`MongoDbContext.SetGuidRepresentation(MongoDB.Bson.GuidRepresentation.CSharpLegacy)`. More info [here](https://github.com/alexandre-spieser/mongodb-generic-repository/issues/7).
