Silverlight 3 Could Not download the silverlight Application

I created a simple Silverlight 3 app.

<UserControl x:Class="SilverlightApplication2.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480">
    <Grid x:Name="LayoutRoot">
        <TextBlock Text="Hello World!" ></TextBlock>
    </Grid>
</UserControl>

When I run it I get an error about not being able to download the silverlight app

Line: 56
Error: Unhandled Error in Silverlight Application
Code: 2104   
Category: InitializeError      
Message: Could not download the Silverlight application. Check web server settings   

Well if you look in the ClientBin folder you will see it is empty so the xap file is not available to be used

To fix this right click on the web application and select Build Order.  On the Dependencies tab make sure the Checkbox next to the Silverlight app is checked.

Windows 7 RC User Profile Service Failed the Logon

I upgraded my laptop the other day to use Windows 7 RC.  I am really liking the speed improvements and the windows virtual pc that it comes with. Dont forget to enable virtualization on your microprocessor in your computer's bios settings if you want to use windows virtual pc.

 The other day after the upgrade I was not able to log into my account. I got an message User Profile Service Failed the Logon.   The error was caused by a messed up registry key for the user profile for my account.  Well I was able to boot into safe mode and follow the instructions in this post in the Windows Vista Forums and fix the problem.
