I have the feeling that you have to spend more time to check the internal conditions...
LinqConnect is fast, comfortable, but I feel you released 2.5 without comprehensive testing.

Could you please describe in more details the scenario, in which this problem occurs? For example, please describe the entity being inserted (i.e., the data types used in its members, and whether it has associations or participates in an inheritance hierarchy). If possible, please send us the script needed to generate the corresponding database table, or the model you are working with.

We couldn't reproduce the problem in simple situations.
