Problem with data sources-Unable to load NetTiersServiceSection

I get an error in VS design view for all of the screens that use any of the DataSourceControl objects, including the Admin screens that are automatically generated.  The error displayed is "Error Creating Control   Unable to load NetTiersServiceSection"

I have tried this with multiple databases (including Petshop), thinking that there might be a naming conflict causing it, but the same things occurs on all of them.  The admin pages build and work without errors, but they can't be edited in design view.  If I cut out the data source, like the example below, the error disappears and I can view the controls.

<data:OrdersDataSource ID="OrdersDataSource" runat="server"
   SelectMethod="GetPaged"
   EnablePaging="True"
   EnableSorting="True"
>   <Parameters>
    <data:CustomParameter Name="WhereClause" Value="" ConvertEmptyStringToNull="false" />
    <data:CustomParameter Name="OrderByClause" Value="" ConvertEmptyStringToNull="false" />
    <asp:ControlParameter Name="PageIndex" ControlID="GridView1" PropertyName="PageIndex" Type="Int32" />
    <asp:ControlParameter Name="PageSize" ControlID="GridView1" PropertyName="PageSize" Type="Int32" />
    <data:CustomParameter Name="RecordCount" Value="0" Type="Int32" />
   </Parameters></data:OrdersDataSource>

One thing I noticed is that the NetTiersServiceSection is named slightly different in the generated Web.Config vs the one that is displayed in the summary report.

 Web.Config

<section name="Petshop.Data" type="Petshop.Data.Bases.NetTiersServiceSection, Petshop.Data" allowDefinition="MachineToApplication" restartOnExternalChanges="true"/>

SummaryReport

<section name="netTiersService" type="PetshopTest.Data.Bases.NetTiersServiceSection, PetshopTest.Data"  allowDefinition="MachineToApplication" restartOnExternalChanges="true" />

I tried renaming the section in Web.Config to NetTiersService, but get the same result.

I am using VS2005, .NetTiers 2.2, and CodeSmith Professional 4.1.2.

Has anyone else had this problem? 

 Thanks,

Daryl

I was working with multiple versions of the application and database and accidentally copied the SummaryReport line from the wrong window.  It should have read:

<section name="netTiersService" type="Petshop.Data.Bases.NetTiersServiceSection, Petshop.Data"  allowDefinition="MachineToApplication" restartOnExternalChanges="true" />

I fixed this by installing Service Pack 1 for VS2005.

 The install of VS2005 SP1 worked for a few weeks, but I am now getting the same error message again on all of the projects that were working.  I can work around the problem by cutting out the <data: sections from the page while laying out the pages and paste them back in when ready to run, but that is a hassle.  Any help would be appreciated.

??? After rebooting, the error went away in one of the applications.  Another still isn't working, but is giving a different error.  The issue has to be in how VS resolves references in the designer, not in the code itself.
