Advantage .NET data provider

Question

I have installed advantage .net data provider i also added the data items into the tool box like (AdsCommand, AdsConnection, and AdsDataAdapter). i also added a reference of Advantage.Data.Provider in reference when i am using the using statement like using Advantage.Data.Provider; it says a namespace or assembly does not exists i also check the machine config file where this entry is present over there ...

 

What would be the issue

the error is the type or namespace advantage could not be found are you missing a using directive or assembly reference
