Duplicate datasource on WCF Service reference

I am using Entity Framework, adding WCF Service Reference at my Web client I see that there are duplicate entity objects (ComplianceEF开发者_运维百科ileDetail.datasource & ComplianceEFileDetail1.datasource) shown in Reference.svcmap.

Can anyone help me this is important and need immediate solution.

Thanks in advance

there was a class created with the same name as in the database which caused this issue.
