Compile-time conundrum

Question

I asked this over in the WPF General forum and was advised to move it here (nobody could see what was wrong this code, I guess).

'm trying to add a style to my App.xaml file, which looks like this:

<Application x:Class="WPFShowcaseApp.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    StartupUri="Window1.xaml">
    <Application.Resources>
        <Style x:Key="WackyButtonStyle" TargetType="{x:Type Button}">     
            <Setter Property="Height" Value="200" />      
            <Setter Property="Width" Value="75" />      
            <Setter Property="VerticalAlignment" Value="Top" />      
            <Setter Property="FontSize" Value="11pt" />    
        </Style>
    </Application.Resources>
</Application>

..but I'm getting a slew of err msgs. The first one is: "The Element type 'System.Windows.Style' does not have an associated TypeConverter to parse the string '"

...and then there's a ton like this: "A value of type 'String' cannot be added to a collection or dictionary of type 'SetterBaseCollection'."

What am I missing here (conceptually or literally)?

Answer 1

I cannot see anything wrong with this code, Clay.

I've tried adding it to a fresh WPF project's app.xaml in VS2008 SP1, and it gave me no errors and compiled just fine.

I even tried applying the style to a few buttons in a window1.xaml file and saw the anticipated results

<Button Style="{StaticResource ResourceKey=WackyButtonStyle}" >StyledButton</Button>

I think there must be some other problem at work in your project or your installation.

If you create a brand-new WPF project on your machine, and paste the Application.Resources block above into your app.xaml, do the same issues apply?

Answer 2

Thanks; I added it to a new project, and there was no problem. I guess "Gremlins" infested the other one.
