[mapguide-users] Load Layer Definition XML

[clarkie342]

I have couple of questions regarding use of Maestro API

>> when using Maestro API, am I technically replacing MGE Web Tier API?

>> Should I be replacing 

        MapGuideApi.MgInitializeWebTier(CommonUtilities.configPath)
        Dim userInfo As MgUserInformation = New MgUserInformation(session)
        Dim Mysiteconn As MgSiteConnection = New MgSiteConnection()
        Mysiteconn.Open(userInfo)

with

conn = New LocalNativeConnection("webconfig.ini", username, password, "en")
or do I still need both?

Thanks.
