Lab 03 - ASP.NET Core

1. Create an empty ASP.NET Core Web Application
2. Add a simple HTML page (e.g. HelloWorld.html)
3. Try to access this HTML page from the browser
4. Enable returning a static HTML page
5. Use the Map method to create a simple route returning content to the client
6. Return data that is sent passing a parameter to the client, e.g. server:port/Sample3?x=Hello
7. Pass x=<h1>Hello</h1> from the client and return
8. Pass x=<script>alert('hacker');</script> from the client and return it

  <br />
  <button type="submit">Submit</button>
</form>

Dependency Injection

1. Create a custom service and a concrete implementation class
2. Add this service to the dependency injection container
3. Create a custom controller SampleController with constructor injection
4. Create another Map and use the custom controller

Middleware

1. Create and use a custom middleware
2. Define an extension method for easy use of the middleware
3. Add your own middleware to be used for each request

Questions:

2. Which dependency injection framework is used with ASP.NET Core?
