Issue with Graph Diff and Guids #20

Closed bzuillsmith closed 6 years ago

bzuillsmith commented 6 years ago

I'm attempting to use GraphDiff with an MS Access DB and one of my entities uses a Guid. I get Primitive type kind Guid is not supported by the Jet Provider when running GraphDiff.UpdateGraph(...) on this particular entity.

The line it occurs on is here. I notice the Guid case goes to this exception. https://github.com/bubibubi/JetEntityFrameworkProvider/blob/8c6a21275667fd3e5619b8547137b9401a4088ef/JetEntityFrameworkProvider/GeneratorSql/SqlGenerator.cs#L981-L984

Why isn't .ToString() just called on the Guid? I don't fully understand how GraphDiff does things to end up with the Guid as a constant expression. Is there a reason JetEntityFrameworkProvider doesn't allow that or is this just a bug?
