Question

Even though the solution is so obvious I should have never have posted this, I’m leaving it up as a reminder and a useful point of reference to others.

I’ve got the following in my app.config file:

<sectionGroup name='spring'>   <section name='context' type='Spring.Context.Support.ContextHandler, Spring.Core'/>   <section name='objects' type='Spring.Context.Support.DefaultSectionHandler, Spring.Core' /> </sectionGroup> 

Followed by:

<spring>   <context>     <resource uri='config://spring/objects'/>   </context>   <objects xmlns='http://www.springframework.net'>     <object name='mediaLibrary' type='AlbumLibraryWPF.AlbumLibrary, AlbumLibraryWPF'/>   </objects> </spring> 

Then in my app I’ve got:

using Spring.Context; using Spring.Context.Support;  public partial class AlbumChecker : Window {     private DataTable dataTable;      private Library library;     private Thread libraryThread;      public AlbumChecker()     {         InitializeComponent();          CreateToolTips();          IApplicationContext ctx = ContextRegistry.GetContext();         library = (Library)ctx.GetObject('mediaLibrary');          // Other initialisation     }      // Other code } 

It all compiles quite nicely, however, I’m getting an exception raised on the call to GetContext():

Error creating context 'spring.root': Could not load type from string value 'AlbumLibraryWPF.AlbumLibrary, AlbumLibraryWPF'. 

I’ve checked the Spring.NET documentation and can’t see what I’m doing wrong – but I clearly have got something wrong, otherwise it wouldn’t raise the exception!

AlbumLibraryWPF is the namespace and AlbumLibraryWPF.AlbumLibrary is the fully qualified name of the class I want to instantiate. I’m guessing that it’s this I’ve got wrong, but can’t see how.

Answer 1

I feel such a fool.

It was because I’d failed to copy the AlbumLibrary.dll to the correct output directory. That meant that Spring couldn’t find it – even after I’d fixed the assembly name problem Kent highlighted.
