Binding the Loaded event?

Question

I am trying to display a login window once my MainWindow loads while sticking to the MVVM pattern. So I am trying to Bind my main windows Loaded event to an event in my view

Answer 1

Update:

I made a post about a new more flexible version of the method binding that uses a slightly different syntax here:

The full code listing is available here:

Any future updates will be posted to the blog so I suggest checking there for the latest version.

Original Answer:

.NET 4.5+ supports markup extensions on events now. I used this to create a method binding that can be used like this:

View model method signatures:

public void OpenFromFile();
public void Save(DocumentModel model);
public void Edit(DocumentModel model);

public void SetWebServiceState(bool state);

public void SetCurrentElement(DesignerElementTypeA element);
public void SetCurrentElement(DesignerElementTypeB element);
public void SetCurrentElement(DesignerElementTypeC element);

public void StartDrawing(MouseEventArgs e);
public void AddDrawingPoint(MouseEventArgs e);
public void EndDrawing(MouseEventArgs e);

public class Document
{
    // Fetches the document service for handling this document
    public DocumentService DocumentService { get; }
}

public class DocumentService
{
    public void Save(Document document);
}
