New features:

#24 Allow configuring default plugin that is returned from DI

ASP.NET Core specific new feature which extends the AddPluginType-feature with an option to configure the default plugin type. Here's how this feature can be used:

Previously always resolved the first IOperator:

            services.AddPluginType<IOperator>();

Now:

            services.AddPluginType<IOperator>(configureDefault: option =>
            {
                option.DefaultType = (provider, types) => typeof(SumOperator);
            });

Or:

            services.AddPluginType<IOperator>();
            
            services.Configure<DefaultPluginOption>(nameof(IOperator), option =>
                option.DefaultType = (serviceProvider, implementingTypes) => typeof(MultiplyOperator));

Please view #24 for more details for the background of this feature.

Bug fixes:

#44 Unnecessary assembly loading

Fixed a bug which caused FolderPluginCatalog to load more assemblies than needed when FolderPluginCatalogOptions were used to define the type finding criteria.
