Unknown connection option error

I'm trying to learn VB and have written a program to choose a restaurant. I'm using Microsoft Visual Basic 2010 Express and the DB is SQL Server Compact 3.5.  the program is a Windows Form application.  The user chooses a series of options and then clicks a button. On buttonclick a SQL query is generated based on their choices. I'm having a problem returning my results in a datagridview. 

The error I'm getting is " Unknown connection option in connection string: .net framework data provider for microsoft sql server compact 3.5data source." The relevant code is:

Dim conAsNew SqlServerCe.SqlCeConnection

       Dim dbProvider AsString

       Dim dbSource AsString

       Dim ds As NewDataSet

       Dim da As SqlServerCe.SqlCeDataAdapter

       dbProvider = ".NET Framework Data Provider for Microsoft SQL Server Compact 3.5"

       dbSource = "Data Source = C:\Users\mkg\Documents\Visual Studio 2010\Projects\vbLunch\WindowsApplication1\Restaurants.sdf"

       con.ConnectionString = dbProvider & dbSource

       con.Open()

       da = New SqlServerCe.SqlCeDataAdapter(conditions, con)

       da.Fill(ds, "Pick")

I'm fairly sure that both the dbprovider and dbsource are correct - I got the provider from the properties of the DB and I've verified the path to the DB, so I have no idea what's wrong. "Conditions" is the sql query that is generated based on the user's choices. I know the query is  formatted correctly because I was able to test that using a MsgBox. On the form, the datagridview's datasource is set to UseThisOne.Restaurants.Fill,GetData(). It does return results if I Preview it.

Hopefully I've provided enough info but I'll be happy to update my question if I've missed anything.
