Serenity Application Platform

What is the Serenity Platform

Serenity is an ASP.NET Core / TypeScript application platform designed to simplify and shorten the development of data-centric business applications with a service-based architecture.

It aims to make development easier while reducing maintenance costs by avoiding boiler-plate code, reducing the time spent on repetitive tasks, and applying best software design practices.

Online Demo

https://demo.serenity.is

Quickstart

Premium customers should use the StartSharp template which they can download from the Serenity members area.

Ensure you have the necessary requirements installed.

# Install/Update Serene.Templates package.
> dotnet new install Serene.Templates

# Create a new Serene project.
> dotnet new serene -n MySereneApp

# Navigate into your project folder.
> cd MySereneApp/MySereneApp.Web

# Install NPM packages.
> npm i

# Build and run the project.
> dotnet run

That's it! ✨ You can visit http://localhost:5000 (actual port may vary, check the console after dotnet run) to access your Serenity application.

Release History

VersionChangesUrgencyDate
10.6.0 ### Features - Add `ListRequestCapabilities` and `[ListRequestCapabilities]` attribute so list handlers can declare supported operations. `ServiceLookupEditor` now uses these capabilities, can infer lookup endpoints from row metadata, and supports primitive list responses. - Add `IncludeMore` to `ListRequest` and `More` to `ListResponse`, allowing callers to check for another page without requiring a total count. Add configurable default and maximum page sizes (`RequestHandlerSettings.DefaulHigh10/12/2026
10.5.2### Features - Enable nullable reference types across the framework and common, pro and business feature projects (`<Nullable>enable</Nullable>`), and `<Nullable>annotations</Nullable>` for tests / Serene / StartSharp. New projects created from the Serene and StartSharp templates now use `<Nullable>annotations</Nullable>` by default (previously nullable was disabled). This only enables nullable annotations, not warnings, so existing code keeps compiling without nullable warnings. If you want fuHigh9/16/2026
10.5.0### Features - Add full async request handler support for Save, Delete, Retrieve, List and Undelete request handlers. `SaveRequestHandler`, `DeleteRequestHandler`, `RetrieveRequestHandler`, `ListRequestHandler` and `UndeleteRequestHandler` are split into sync base classes and new `...Async` variants (e.g. `SaveRequestHandlerAsync`, `ListRequestHandlerAsync`). New interfaces like `ISaveHandlerAsync`, `IDeleteHandlerAsync`, `IRetrieveHandlerAsync`, `IListHandlerAsync`, `IUndeleteHandlerAsync` andHigh9/6/2026
10.4.0### Features - Add connection key fallback support (`IConnectionKeyFallbacks`). `DefaultConnectionStrings` and `DefaultSqlConnections` are now driven by assembly-level `ConnectionKeyFallback` attributes, so feature modules can declare their own logical connection key (e.g. `ProMeeting`) while still working in applications that only configure a fallback key (e.g. `Default`). A fallback can also be set via configuration with `Data:(ConnectionKey):FallbackFor`, which accepts a semicolon separated High9/1/2026
10.3.7### Features - Add more service collection extensions to simplify service registration in Startup.cs: `AddClamAVUploadScanner`, `AddElevationHandler`, `AddEmailSender`, `AddPasswordStrengthValidator`, `AddHttpContextItemsAccessor`, `AddCssBundling`, `AddCssAndScriptBundling`, `AddScriptBundling`, `AddLocalTextInitializer` and an `AddUploadStorage` overload. Add `AddBackgroundJobs`, `AddPuppeteerHtmlToPdf` and `AddSecureUploadFileResponder` (StartSharp). - `TranslationRepository` now uses `ILocHigh8/12/2026
10.3.5### Features - Make EntityDialog methods like `save`, `loadById`, `delete`, etc. return a promise. This might be a breaking change if you have any code that overrides these methods and does not return a promise. - Apply EntityDialog promise return changes to EntityGridDialog (StartSharp) - Bring back custom component overload for the `jsx` function. - Switching to TypeScript 7. `dts-bundle-generator` still needs to use TypeScript 6 as TS7 does not have an API yet. - Allow `editSettings` fHigh7/27/2026
10.0.1### Features - First .NET 10 version. You'll need to install Visual Studio 2026 and .NET 10 SDK. - Please stay at 9.2.x versions if you still need to use Visual Studio 2022 and .NET 8. - Strict Content-Security-Policy (CSP) is enabled in StartSharp template by default. - AddCspDirective overloads for ControllerBase and HttpContext - Instead of using sleek-vars.rtl sleek-vars.ltr etc. change the values of --l, --r variables based on rtl. Increase number of supported columns to 100 from 50 Low11/24/2025
9.1.3- `@serenity-is/domwise` is our new library to create DOM elements with full TypeScript support. It is primarily based on [jsx-dom](https://github.com/alex-kinokon/jsx-dom) with integrated signal support via [@preact/signals-core](https://github.com/preactjs/signals) and some extra types / ideas from [ryansolid/dom-expressions (SolidJS)](https://github.com/ryansolid/dom-expressions) and [lusito/tsx-dom](https://github.com/Lusito/tsx-dom). `@serenity-is/domwise` also exports signal functions likeLow11/14/2025
9.0.0- **Type registration via decorators** (e.g., `Decorators.registerClass`, `Decorators.registerEditor`, etc.) is now deprecated (it still works but is not recommended): ```ts import { Decorators, Widget } from "@serenity-is/corelib"; @Decorators.registerClass("MyProject") export class MyType extends Widget<any> { } ``` Instead, use a static `[Symbol.typeInfo]` property declaration: ```ts import { Widget } from "@serenity-is/corelib"; expLow10/10/2025
