How to use namespaces in XAML WPF including to refer to a converter (maybe other code too)

Place in header part of file. My initial mistake was
    xmlns:local="clr-namespace:MyConverters
Should have been
    xmlns:local="clr-namespace:OneWay.WPF.MyConverters
Need to include the assembly, even if it is the same project.
In this code local gives the namespace a short name.

Next using the namespace in XAML

<Style.Resources>
    <local:ButtonCenterConverter x:Key=”DivideByTwo”></local:ButtonCenterConverter>
</Style.Resources>

How to use Application.Resources and also ResourceDictionaries in WPF

Application.Resources

The help page in MSDN is at:

http://msdn.microsoft.com/en-us/library/ms746624.aspx?lc=1033

I originally got this wrong, by trying to create a new Resource dictionary and placing the XAML <Application.Resources> into this new file.
When you create a new WPF application, an Application.xaml file is created automatically. This already contains an <Application.Resources> section, so just add in your new resources direct into here.

How to use Resource Dictionaries

Create Resource Dictionary, possibly putting it in a different folder, perhaps named Assets.
Then in Application.xaml

<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source=”Assets\Dictionary1.xaml” />
<ResourceDictionary Source=”Assets\Dictionary2.xaml” />
</ResourceDictionary.MergedDictionaries>
<ResourceDictionary>
</Application.Resources>

<–Seem to be only able use Resoure Dictionary or Application.Resources not a mix of both
So Following line is invalid, because of following ResourceDictionaries
May be possible if a Key is used somewhere>–>
<!–<Brush x:Key=”myColorYellow”>Yellow</Brush>–>

Error 1

If on a window or page and “The designer does not support loading dictionaries that mix “ResourceDictionary” items without a key and other items in the same collection”

Solution 1:

Put the other resources inside the ResourceDictionary even if they are designed there.

How to store Resource Dictionaries in a separate assembly and use them

In the following example of use. RDL01 is an external assembly. The word “component” is there as seen here.

<StackPanel>
<StackPanel.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source=”/RDL01;component/Dictionary1.xaml”></ResourceDictionary>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</StackPanel.Resources>
<Button Content=”Hello” Width=”100″ Height=”50″></Button>
