  - Organizes ASP.NET Core Minimal Apis in REPR pattern endpoints
- - Encapsulates endpoint behaviors like request validation, request handling, and response mapping.
+ - Encapsulates endpoint behaviors like request validation, request handling, and response mapping*.
  - Supports anything that Minimal Apis does. Configuration, parameter binding, authentication, Open Api tooling, filters, etc. are all Minimal Apis under the hood.
  - Supports auto discovery and registration.
  - Has built-in validation support with [FluentValidation](https://github.com/FluentValidation/FluentValidation). If a validator is registered for request model, request is automatically validated before being handled.
  - Supports constructor dependency injection in endpoint implementations.
  - Enforces response model type safety in request handlers.
  - Abstracts the logic for converting business results into HTTP responses.

 WebResultEndpoint and ServiceResultEndpoint, the two abstract endpoint bases, have a 'HandleAsync' method which returns a strongly typed [business result](https://github.com/modabas/ModResults).

+These two endpoint types differ only in converting these business results into HTTP responses before sending response to client.

+MinimalEndpoint within ModEndpoints.Core package, is closest to barebones Minimal Api. Its 'HandleAsync' method support the following types of return values:

+- string
+- T (Any other type)
+- Minimal Api IResult based

+Other features described previously are common for all of them.
 
 Each type of andpoint has various implementations that accept a request model or not, that has a response model or not.

 ### ServiceResultEndpoint
 
 A ServiceResultEndpoint implementation, after handling request, encapsulates the [business result](https://github.com/modabas/ModResults) of HandleAsync method in a HTTP 200 Minimal Api IResult and sends to client. The [business result](https://github.com/modabas/ModResults) returned may be in Ok or Failed state. This behaviour makes ServiceResultEndpoints more suitable for internal services, where clients are aware of Result or Result<TValue> implementations.

 ### WebResultEndpoint
 
-A WebResultEndpoint implementation, after handling request, maps the [business result](https://github.com/modabas/ModResults) of HandleAsync method to an IResult depending on the result type, state and failure type (if any). Mapping behaviour can be modified or replaced with a custom one.
