Question

I’m trying to do some data binding to an enum on WPF, but I’m getting an exception.

1. First I have my NS declaration, pointing to the reference I have added to the project:

   xmlns:defs="clr-namespace:API.Definitions;assembly=API"

   and also:

   xmlns:sys="clr-namespace:System;assembly=mscorlib"

2. Then I’m adding an enum to the window resources:

   <Window.Resources
               <ResourceDictionary>
                   <ObjectDataProvider x:Key="someEnum"
                                   MethodName="GetValues" 
                                   ObjectType="{x:Type sys:Enum}">
                       <ObjectDataProvider.MethodParameters>
                           <x:Type TypeName="defs:someEnum" />
                       </ObjectDataProvider.MethodParameters>
                   </ObjectDataProvider>
               </ResourceDictionary>
    </Window.Resources>
   

3. I’m trying to use it on a combo box:

   ComboBox ItemsSource="{Binding Source={StaticResource someEnum}}"

4. Running it and getting a XamlParseException:

Type reference cannot find type named '{clr namespace:API.Definitions;assembly=API}someEnum'.

I have browsed this API reference and I can clearly see that enum and use
it on code if I’d like. I have also tested binding to a local enum (not referenced),
and this works perfectly.

Some answers implied that removing the assembly=API from xmlns:defs=”clr-namespace:API.Definitions;assembly=API” should solve this, but it doesn’t.

Thanks for your help.

Answer 1

Okay, I have found what was causing it — the referenced API was built for x86 rather than “Any CPU”. Any explanation for this?
