Mono.Addin implementation doesn't retrieve addins
c#, mono.addins, plugins
Solution
The problem here is that the extension point for IOrganizerPlugin is defined in project1, which is not an addin nor an add-in root. The solution is to add this reference in project2:
[assembly:ImportAddinAssembly ("project1.dll")]
In this way project1 becomes part of the App.Organizer add-in root, and the extension points in project1.dll will be correctly registered.
Problem
I'm writing an extendible application using Mono.Addins framework, C# and visual studio 2010. the structure of my application is the following: project1: ``` namespace Plugins { [TypeExtensionPoint] public interface IPlugin<InitParamsType> { void Refresh(); string PlugInName { get; } void Initialize(InitParamsType parameters); } [TypeExtensionPoint] public interface IOrganizerPlugin : IPlugin<string> { bool AllowsToEditBrandCode { get; } UserControl GetUI(); } public interface IPluginHost<PluginSpecalizedType> { void EmbedPlugin(PluginSpecalizedType plugin); } } ``` project 2 (references project1): ``` [assembly: AddinRoot("App.Organizer", "1.0")] namespace App.Organizer { public partial class frm_Supplier_Managed : Form, IPluginHost<IOrganizerPlugin> { public frm_Supplier_Managed() { AddinManager.Initialize(); AddinManager.Registry.Update(null); foreach (IOrganizerPlugin Addin in AddinManager.GetExtensionObjects(typeof(IOrganizerPlugin))) { EmbedPlugin(Addin); } } public void EmbedPlugin(IOrganizerPlugin plugin) { //embedding UI and so on.. } } } ``` project 3 (references project 1): ``` [assembly: Addin("App.OrganizerPro", "1.0")] [assembly: AddinDependency("App.Organizer", "1.0")] namespace App { [Extension] public class MainPlugIn : IOrganizerPlugin { public void Refresh() { return; } public string PlugInName { get { return ""; } } public void Initialize(string supplierCode) { } public UserControl Interface { get { return null; } } public bool AllowsToEditBrandCode { get { return true; } } public UserControl GetUI() { return null; } } } ``` the problem is: in the foreach statement no plugins are yielded. p.s.: all .dll are compiled in the same directory.
