Question

Has anyone been able to get an extension up and running Expression Blend + Sketchflow preview? I’m looking for an example project.

I was following this article, but it is a bit outdated.

So far I:

• Created a .Net 4.5 class library project
• Added a reference to the Microsoft.Expression.Extensibility.dll in the new Blend Preview directory
• Set my project to deploy to the appropriate Addins directory
• Setup Visual Studio to run the new Blend.exe for debugging
• Hooked up MEF and inherited IPlugin as in the example

But my plugin doesn’t seem to load and no breakpoints are hit.

After reading your question I decided to start working on a new version of that tutorial.

A few things to get you started right away.

I’ve created the basic plugin like this:

using System.ComponentModel.Composition;
using Microsoft.Expression.Extensibility;

namespace Demo.Extension
{
    [Export(typeof (IPackage))]
    public class Demo : IPackage
    {
        public void Load(IServices services)
        {
        }

        public void Unload()
        {
        }
    }
}

Make sure you:

• place the plugins in …\Blend Preview\extensions
• run visual studio as administrator to be able to deploy to that folder during debug
• implement the IPackage instead of IPlugin
