jQuery 3.6.0 منتشر شد
jQuery 3.6.0 has been released! In jQuery 3.5.0, the major change was a security fix for the html prefilter. This release does not include a security fix, but does have some good bug fixes and improvements. We still have our eyes on a jQuery 4.0 release, but until then we will continue to support the 3.x branch and address important issues.

پیاده سازی UnitOfWork به وسیله MEF
من کلاسهام به این شکله:
کلاس کانتکسهای من
در تعاریف کلاسهایی که از IDBContext ارث میبرن اکسپورت شدن (این یک نمونه از کلاسهای منه)
در طرف دیگر برای لود کردن کلاس زیر نوشتم
و در کانتکس اصلی برنامه این پلاگین هارو لود میکنم
کلاس کانتکسهای من
public class VegaContext : DbContext, IUnitOfWork, IDbContext { #region Constructors (2) /// <summary> /// Initializes the <see cref="VegaContext" /> class. /// </summary> static VegaContext() { Database.SetInitializer<VegaContext>(null); } /// <summary> /// Initializes a new instance of the <see cref="VegaContext" /> class. /// </summary> public VegaContext() : base("LocalSqlServer") { } #endregion Constructors #region Properties (2) /// <summary> /// Gets or sets the languages. /// </summary> /// <value> /// The languages. /// </value> public DbSet<Language> Languages { get; set; } /// <summary> /// Gets or sets the resources. /// </summary> /// <value> /// The resources. /// </value> public DbSet<Resource> Resources { get; set; } #endregion Properties #region Methods (2) // Public Methods (1) /// <summary> /// Setups the specified model builder. /// </summary> /// <param name="modelBuilder">The model builder.</param> public void Setup(DbModelBuilder modelBuilder) { //todo modelBuilder.Configurations.Add(new ResourceMap()); modelBuilder.Configurations.Add(new LanguageMap()); modelBuilder.Entity<Resource>().ToTable("Vega_Languages_Resources"); modelBuilder.Entity<Language>().ToTable("Vega_Languages_Languages"); //base.OnModelCreating(modelBuilder); } // Protected Methods (1) /// <summary> /// This method is called when the model for a derived context has been initialized, but /// before the model has been locked down and used to initialize the context.

public class LoadContexts { public LoadContexts() { var directoryPath = HttpRuntime.BinDirectory;//AppDomain.CurrentDomain.BaseDirectory; //"Dll folder path"; var directoryCatalog = new DirectoryCatalog(directoryPath, "*.dll"); var aggregateCatalog = new AggregateCatalog(); aggregateCatalog.Catalogs.Add(directoryCatalog); var container = new CompositionContainer(aggregateCatalog); container.ComposeParts(this); } //[Import] //public IPlugin Plugin { get; set; } [ImportMany] public IEnumerable<IDbContext> Contexts { get; set; } }

با موفقیت همه پلاگینها لود میشه و مشکلی در عملیات نیست. اما Attributeهای کلاس هارو نمیشناسه. مثلا پیام خطا تعریف شده در MVC نمایش داده نمیشه چون وجود نداره ولی وقتی کلاس مورد نظر از IValidatableObject ارث میبره خطایهای من نمایش داده میشه. میخوام از خود متادیتاهای استاندارد استفاده کنم.

- Microsoft will change how it reports financially.
- Microsoft will become a “consumer-focused enterprise company.”
- Windows will converge into a single code base capable of running on any platform.
- Application development will converge into allowing developers to maintain a single code base for an app that will run on any device capable of running Windows.
- Release frequency will dramatically increase.
- The “modern” user interface is here to stay.
