16.   Repeat with Name Field type tb2 and value “tb2 in english”

17.   In the file Strings.Designer.cs change “internal Strings() {“ to “public Strings() {” Note:  Every time you change the strings.resx you update this reference i hope this gets fixed in the RTM verion

18.   Click Save, press F5 and add debugging to web.config

19.   IE opens up with a blank page

20.   Close IE

21.   Open Page.xaml in xaml editor window

22.   In the user control add a new xml namespace xmlns:Loc="clr-namespace:SL_Loc_Sample.Resources"

23.   Add a locstrings as a  resource to your page eg: <UserControl.Resources><Loc:Strings x:Name="LocStrings" /></UserControl.Resources>

24.   Inside the grid add a Textblock and bind it to your resource Tb1 eg: <TextBlock Text="{Binding tb1, Source={StaticResource LocStrings}}" />

25.   The String should appear in the Design view above

26.   Wrap the textblock inside a vertical stackpanel  and add a second Textkblock

        <StackPanel Orientation="Vertical">

           <TextBlock Text="{Binding tb1, Source={StaticResource LocStrings}}" />

           <TextBlock Text="{Binding tb2, Source={StaticResource LocStrings}}" />

31.   Notice the file %HOMEPATH%\Documents\Visual Studio 2008\Projects\SL_Loc_Sample\bin\debug\de\SL_Loc_Sample.resources.dll appears but is not embedded in your xap yet

32.   To add that market to your xap you must open the .csproj in notepad  (ugly workaround until SL2.0 tools RTW)

33.   Update SupportedCultures to <SupportedCultures>de</SupportedCultures>

34.   Save and close

35.   VS 2008 will ask you to reload project, click reload

36.   Next we need to update the SL browser object reference

37.   Id recommend you delete the SL_Loc_SampleTestPage.aspx and set SL_Loc_SampleTestPage.html as your start page

38. In SL_Loc_SampleTestPage.html  Add the culture and uiculture params to your object

<object data="data:application/x-silverlight," type="application/x-silverlight-2-b2" width="100%" height="100%">

            <param name="source"v value="ClientBin/SL_Loc_Sample.xap"/>

            <param name="onerror" value="onSilverlightError" />

            <param name="background" value="white" />

            <param name="culture" value="de" />

            <param name="uiculture" value="de" />

      </object>

39.   Click Save, press F5

40.  IE should open up with the German strings
