I'm not sure if this is an option for you, but I ended up using an ArcView licence to connect to the GDB. Here is my Code:
Imports ESRI.ArcGIS.esriSystem
Imports ESRI.ArcGIS.esriSystem.esriExtensionState
'Open an ArcView License (To connect to the .GDB)
Dim init As New AoInitialize()
If Not init.Initialize(esriLicenseProductCode.esriLicenseProductCodeArcView) = esriLicenseStatus.esriLicenseCheckedOut Then
Return False
End If
'Open a Connection to the .GDB
Dim cn As OleDbConnection = FileGdbConnection(GDB_Path)
cn.Open()
'Fill a DataTable will all the information from TABLE_NAME
Dim cmd As New OleDbCommand("SELECT * FROM TABLE_NAME", cn)
'Dim cmd As New FileGDBCommand("SELECT * FROM TABLE_NAME", cn)
Dim dt As New DataTable("TABLE_NAME")
dt.Load(cmd.ExecuteReader())
'Close Connections
cn.Dispose()
init.Shutdown()
Public Function FileGdbConnection(ByVal Path As String) As OleDbConnection
' Build the connection string.
Dim fileGdbStringTemplate As String = "Provider=ESRI.GeoDB.OleDB.1;Data Source={0};" & "Extended Properties=workspacetype=esriDataSourcesGDB.FileGDBWorkspaceFactory.1;"
Dim connectionString As String = String.Format(fileGdbStringTemplate, Path)
' Create the connection and return it.
Dim fileGdbConn As OleDbConnection = New OleDbConnection()
fileGdbConn.ConnectionString = connectionString
Return fileGdbConn
End Function
