I am busy building a windows forms application that needs to be able to use a WCF to connect to the work Database.

I get how to reference it but now I was told to create a DAL project and Classes project to contain all my methods and that's where I get really confused because my Classes.cs has SQL commands in it and now I have to call the method in the WCF and then get that method in the app it self here is the code that I use in the classes.cs but how would I then reference this in the WCF and then to the App it self via code?
private DataTable getLoginDetails(string username)

            SqlCommand sqlcmd = new SqlCommand("sp_GetLoginDetails", sqlConn);
            sqlcmd.CommandType = CommandType.StoredProcedure;

            sqlcmd.Parameters.Add("@UserName", SqlDbType.VarChar).Value = username;
            DataTable dtUser = new DataTable();
            SqlDataReader sqlDR = sqlcmd.ExecuteReader();

            BGAssetService.Service1Client serviceAsset = new BGAssetService.Service1Client();

            return dtUser;

I don't understand what's your problem. Can you try to describe your scenario better?
Do you just want to call the Service from your "DAL", or should the "DAL" be a WCF-Service you can call from client side?
If you know how to "reference" your WCF-Service so you can call it, I can't imagine what hinders you to do the same from another roject (your new class-library)?

1 solution

1. Create OperationContracts and DataContracts
2. Update your service Reference.
3. Create WCF client in your app
4. You'll get the method refernce
