What's up with that? If you read Raymond Chen's blog , you already have a pretty good guess: Backwarden-USCommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.msdn.com/smartclientdata/archive/2005/10/14/481238.aspx#491650Fri, 11 Nov 2005 06:11:58 GMT91d46819-8472-40ad-a661-2c78acb4018c:491650diegovI think you also do it for _Module, but I haven't checked if Module is a valid identifier in VB.NET 8.http://blogs.msdn.com/smartclientdata/archive/2005/10/14/481238.aspx#600841Thu, 18 May 2006 13:32:09 GMT91d46819-8472-40ad-a661-2c78acb4018c:600841RagaHi, As the DataSetgenerator creates public properties that start with an underscore, VS.NET throws up warnings saying "'MS.IT.Ops.Hermes.DataTransferObjects.ComponentEnterpriseProducts._ComponentEnterpriseProducts' is not CLS-compliant".
