• Debugging with MVC Sources
• Simply add path to sources in global.json

Asp.net core 1.0 (Peter Himschoot)
- 1. ASP.NET Core 1.0 Deep Dive Peter Himschoot
- 2. About me • Peter Himschoot • Trainer for U2U • .NET • Web • iOS • Microsoft Regional Director for BeLux • Independent developer evangelist
- 3. Agenda • We’re going to talk about extensibility • Middleware • Tag Helpers • Customization • …
- 4. ASP.NET Core Pipeline Building your own middleware
- 5. ASP.NET Core Pipeline ResponseRequest Middleware
- 6. Existing Middleware • Static files • Routing • Error Handling • MVC app.UseExceptionHandler("/Home/Error"); app.UseStaticFiles(); app.UseMvc(routes => { routes.MapRoute( name: "default", template: "{controller=Home}/{action=Index}/{id?}"); }); app.UseRouter(routes);
- 7. Your own middleware • Build class implementing • Use extension method to install it Task Invoke(HttpContext context) public static IApplicationBuilder UsePrimeChecker( this IApplicationBuilder builder, PrimeCheckerOptions options) => builder.Use(next => new Middleware(next, options).Invoke); }
- 9. Unit Testing • Fully supported in .NET Core 1.0 • Need to add the test runner as a command "dependencies": { "xunit": "2.1.0", "xunit.runner.dnx": "2.1.0-rc1-build204", "Microsoft.AspNet.TestHost": "1.0.0-rc1-final", "IsPrime": "1.0.0-*" }, "commands": { "test": "xunit.runner.dnx" }
- 10. Integration Testing • ASP.NET Core 1.0 supports testing website without host // Arrange var server = new TestServer(TestServer.CreateBuilder().UseStartup<Startup>()); var client = server.CreateClient(); // Act string request = "/checkprime?5"; var response = await client.GetAsync(request); response.EnsureSuccessStatusCode(); var responseString = await response.Content.ReadAsStringAsync(); // Assert Assert.Equal("5 is prime!", responseString);
- 11. MVC6 Tag Helpers Building your own tag helper
- 12. Taghelpers • Enable us to write nicer razor code • Look a lot like angular.js and knockout.js • Example: <ul class="nav navbar-nav"> <li><a asp-controller="Home" asp-action="Index">Home</a></li> <li><a asp-controller="Home" asp-action="About">About</a></li> <li><a asp-controller="Home" asp-action="Contact">Contact</a></li> </ul>
- 13. HtmlHelper vs. Tag helper • Is there any doubt? @Html.EditorFor(model => model.Title, htmlAttributes: new { @class = "form-control"}) <input asp-for="Title" type="text" class="form-control" />
- 14. Building a custom tag helper <ul u2u-property="Address.City" u2u-items="Model"></ul>
- 15. Tweaking Adding nameof() support in Views
- 16. Using C#6 nameof instead of strings • Again?! • I want this! • But it is not supported… • I want this! • So let’s add it… <a asp-controller="@nameof(HomeController)" asp-action="@nameof(HomeController.Index)">Home</a> <a asp-controller="Home" asp-action="Index">Home</a>
- 17. Use the Source Luke! • Debugging with MVC Sources • Simply add path to sources in global.json { "projects": [ "src", "test", "C://Mvc//src" ], "sdk": { "version": "1.0.0-rc1-final" } }
- 18. NuGet projects Building your own NuGet Package
- 19. New Visual Studio projects make this easy! • Using dnu pack command
