The Problem

What they neglect to say is all that testability and persistence ignorance flies right out the window when you create a new ASP.NET Web Application using the MVC template and "Individual User Accounts" authentication. What you get is a single-layered application, tightly coupled to Entity Framework, that:

• Ignores the patterns that facilitate testing, including: the repository pattern, unit of work pattern, and dependency injection;

• Forces you to implement their IUser interface in your application’s User entity, thereby coupling it to ASP.NET Identity;

• Eliminates any clear separation between your entities, persistence concerns, and business logic. Persistence ignorance? Forget about it.

Thankfully, due to the extensibility designed into ASP.NET Identity, it is possible to ditch the reference to the Microsoft.AspNet.Identity.EntityFramework assembly and write a custom implementation that can address these and other architectural issues. Just be forewarned: it is not a trivial undertaking, and you’ll have to put up with some code smell that is baked into the Microsoft.AspNet.Identity.Core assembly. 

We’re excited to announce that starting April 2022, we will be making monthly updates for modern .NET (.NET Core) available for server operating systems via Microsoft Update (MU) on an opt-in basis. 

In this article we are going to discuss how to insert, update and delete data into database using ASP.NET MVC 4.0. There is a Layout page and Data base script that we are going to use for this but we are not going to discuss much  how to create a Layout page and database script here in detail. 

In this post, we are going to write about what we consider to be the best practices while developing the .NET Core Web API project. How we can make it better and how to make it more maintainable.

We are going to go through the following sections:

• Startup Class and the Service Configuration
• Project Organization
• Environment Based Settings
• Data Access Layer
• Controllers
• Actions
• Microsoft.AspNetCore.All Meta-Package
• Routing
• Logging
• CryptoHelper
• Content Negotiation
• Using JWT
• Conclusion  

MockHttp is a testing layer for Microsoft's HttpClient library. It allows stubbed responses to be configured for matched HTTP requests and can be used to test your application's service layer. 

var mockHttp = new MockHttpMessageHandler();

// Setup a respond for the user api (including a wildcard in the URL)
mockHttp.When("http://localhost/api/user/*")
        .Respond("application/json", "{'name' : 'Test McGee'}"); // Respond with JSON

// Inject the handler or client into your application code
var client = mockHttp.ToHttpClient();

var response = await client.GetAsync("http://localhost/api/user/1234");
// or without async: var response = client.GetAsync("http://localhost/api/user/1234").Result;

var json = await response.Content.ReadAsStringAsync();

// No network connection required
Console.Write(json); // {'name' : 'Test McGee'}

Wappalyzer is a cross-platform utility that uncovers the technologies used on websites. It detects content management systems, ecommerce platforms, web frameworks, server software, analytics tools and many more.  

The ASP.NET team has built a command-line tool called HttpRepl. It lets you browse and invoke HTTP services in a similar way to working with files and folders. 

What’s new for performance in .NET Core and ASP.NET Core 3.0 – Ben Adams
One of the biggest advantages of using .NET Core (besides cross-platform support) is the drastic improvements in performance. Because the .NET Core team was able to make minor breaking changes in the runtime and Base Class Library (BCL), lots of stuff was implemented much more efficiently. In this session Ben will dive into the performance improvements in .NET Core in the 3.0 release: runtime changes, JIT changes, intrinsics and a deep dive into some of the improvements making it the best release yet!
