Port to ASP.NET Core 5

[muratcakir]

Parts/modules that require a complete rewrite:

• Plugin Bootstrapper
• Theming engine (most parts)
• Custom Razor stuff
• Bundling & Minification & SASS compiler (BundleTransformer > Custom bundler)
• Autofac: InstancePerRequest > InstancePerLifetimeScope
• Telerik UI components
  • Grid
  • Numeric inputs
• No domain proxies anymore (thanks god). ILazyLoader instead.
• Remove all [Serializable] attributes.
• Remove all [DataContract] and [DataMember] attributes on domain entities. Use [JsonIgnore] for exclusions.
• Datepicker UI component
• Smartstore UI components (> TagHelpers)
• DB Hooking Framework (partially)
• SEO / multilang MVC routing
• Media file middleware
• Authentication > ASP.NET Identity (?)
• PDF engine (> Custom wkhtmltopdf wrapper)
• Newtonsoft.Json > System.Text.Json (?)
• E-Mail sender
• ImageProcessor > ImageSharp
• log4net > NLog | SeriLog
• UrlRewriter > UseRewriter() with AddApacheModRewrite()
• Memory cache
• WebHelper
• QueryString > wrap IQueryCollection
• EF 2nd level cache (https://github.com/VahidN/EFCoreSecondLevelCacheInterceptor)
• EF 2nd level request cache: policy based.
• Implement EF BatchDelete and BatchUpdate
• IO/Disk stuff
• IFileSystem > IFileProvider (?)
• All VirtualPathProviders
• Replace Inflector, Prettifiers etc. with Humanizer library
• Refactor/Move all extension methods that contain DI calls
• Make everything Async
• MimeTypes > FileExtensionContentTypeProvider (for static files)
• Child action > ViewComponent (model binding in child actions > invoke component with PageBase.TryUpdateModel[...])
• ~~Blog/News/Forum/~~Polls > make modules
• SettingService: Cache scopes must be created from caller (no clearCache params anymore)
• Host shutdown > IHostApplicationLifetime.ApplicationStopping
• Change all [DllImport] annotations
• No NameValueCollection anymore. Refactor BuildQueryString() callers accordingly.
• Language resource names with type names in it (e.g. Enums) must be changed.

Web API:

• Migration and sample.
• Replace outdated Swashbuckle component by Swashbuckle.AspNetCore.
• Complex Type with navigation property requires OData ASP.NET Web API > V6.

Performance best-practices

• async/await all the way!
• Use HttpClientFactory to obtain HttpClient instances
• Use EF.CompileQuery where applicable
• Use HTTP response compression
• Always access HttpRequest/HttpResponse body async
• Prefer ReadFormAsync over Request.Form
• Never store IHttpContextAccessor.HttpContext in a field
• Wrap long running processes with many database calls into DbContext.OpenConnection[Async]() or DbContextScope(retainConnection: true)

Architecture

• Use efcore global query filters where applicable

Absolutely no! We gonna keep our self-made web scheduler that solves all dependency scoping and mem leak issues we had before.

Any updates?

Any updates?

The new Smartstore Core repository is private at this moment, we will make it public next week hopefully.

[lucakuehne]

Is there an ETA for the migration to ASP.NET Core?

[muratcakir]

The Beta will be released within the next few weeks.

[stefanmuellerdo]
