Misc (6)

Application Environment

This sample shows how to obtain application environment information (target framework, etc).
Show Connection info

Enumerate the connection information of a HTTP request.
Password Hasher server

Give it a string and it will generate a secure hash for you, e.g. localhost:5000?password=mypassword.
Version info

Show various version info of the framework your system is running on.
IApplicationLifetime

Responds to application startup and shutdown.

We are using IApplicationLifetime that trigger events during application startup and shutdown.
Short Circuit

Use MapShortCircuit or .ShortCircuit() to efficiently respond to a request without going through a middleware pipeline run.

Server-Sent Events (1)

Forever Server

This server will send a 'hello world' greeting forever.

Markdown (2)

Markdown server

Serve markdown file as html file. You will see how you can create useful app using a few basic facilities in aspnetcore.

We take "Markdig" as dependency.
Markdown server - implemented as middleware component

Serve markdown file as html file. It has the same exact functionality as Markdown server but implemented using middleware component.

We take "Markdig" as dependency.

Utils (3)

Status Codes

Here we contrast between the usage of Microsoft.AspNetCore.Http.StatusCodes and System.Net.HttpStatusCode.
MediaTypeNames

This class provides convenient constants for some common MIME types. It's not extensive by any means however MediaTypeNames.Text.Html and MediaTypeNames.Application.Json come handy.
MediaTypeNames - 2

Using FileExtensionContentTypeProvider to obtain the correct MIME type of a filename extension.

Device Detection (1)

The samples in this section rely on Wangkanai.Detection library.

Device Detection

This is the most basic device detection. You will be able to detect whether the client is a desktop or a mobile client.

Image Sharp (1)

All these samples require SixLabors.ImageSharp.Web middleware package. This middleware is an excelent tool to process your day to day image processing need.

Image-Sharp

This example shows how to enable image resizing functionality to your site. It's super easy and the middleware takes care of caching, etc.
