    <p>I'm developing a WPF desktop application with caliburn.micro framework, and I want to configure ninject interceptors so that I can intercept method calls. I would like to do this to handle exceptions in a centralized place, so that I don't have many try-catch blocks everywhere around my code.</p> <p>I haven't been able to acomplish this, because everytime I wire everything up with ninject, the system throws an exception.</p> <p>So here's some code:</p> <p>The AppBootstrapper configure method looks like this:</p> <pre><code> protected override void Configure() { _kernel = new StandardKernel(new NinjectServiceModule()); _kernel.Bind&lt;IWindowManager&gt;().To&lt;WindowManager&gt;().InSingletonScope(); _kernel.Bind&lt;IEventAggregator&gt;().To&lt;EventAggregator&gt;().InSingletonScope(); _kernel.Bind&lt;ISomeViewModel&gt;().To&lt;SomeViewModel&gt;().Intercept().With&lt;SomeInterceptor&gt;() //this is where the exception is thrown; _kernel.Bind&lt;IShell&gt;().To&lt;ShellViewModel&gt;(); } </code></pre> <p>Now the intercept method in my interceptor:</p> <pre><code> public void Intercept(IInvocation invocation) { if (invocation.Request.Method.Name == "TheMethodIWantIntercepted") { try { invocation.Proceed(); } catch (Exception) { Console.WriteLine("I Handled exception"); } } else { invocation.Proceed(); } } </code></pre> <p>The method in the view model looks like this:</p> <pre><code> public virtual void TheMethodIWantIntercepted() { //Some logic here } </code></pre> <p>So that's how interceptors are supposed to work. But it doesn't work, everytime I run the program, and ninject tries to inject the instance of SomeViewModel into ISomeViewModel, the program execution fails, and this is the exception that is thrown (and the stack trace): <a href="http://pastebin.com/qerZAjVr" rel="nofollow">http://pastebin.com/qerZAjVr</a></p> <p>Hope you can help me with this, thank you in advance.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
