Starting with the 2021.2 releases of our .NET productivity tools, including ReSharper and Rider (on Windows), we will require .NET Framework 4.7.2 or newer installed on your machine. Earlier versions of our .NET tools will continue to work on .NET Framework 4.6.1. 

This article introduces you to the in-browser document database known as IndexedDB. With IndexedDB you can create, read, update, and delete large sets of records in much the same way you are accustomed to doing with server-side databases. To experiment with a working version of the code presented in this article, please go to , and the full source code is available via the GitHub repository found at .

.NET Microservices – Full Course, Les Jackson
In this step-by-step tutorial I take you through an introduction on building microservices using .NET. As the name suggests we build everything completely from start to finish –with the full scope of the course outlined in the time-stamp section below. However, at a high-level we’ll cover:

• Building two .NET Microservices using the REST API pattern
• Working with dedicated persistence layers for both services
• Deploying our services to Kubernetes cluster
• Employing the API Gateway pattern to route to our services
• Building Synchronous messaging between services (HTTP & gRPC)
• Building Asynchronous messaging between services using an Event Bus (RabbitMQ)

 

PostSharp 6.0 is the biggest refactoring since the 2.0 version released in July 2010. For a good cause: PostSharp 6.0 now runs natively in .NET Core 2.0. Previous versions of PostSharp executed only under .NET Framework at build time and the support for .NET Core was achieved by using a load of hacks that ended up being unmaintainable, warranting this big refactoring.

Let’s have a look at the new features of PostSharp 6.0 :

• Support for .NET Core 2.0-2.1 and .NET Standard 2.0.
• Support for Portable PDB.
• Support for C# 7.2.
• Ending the PostSharp versioning hell side-by-side: backward compatibility within the same major version.
• Logging: robustness to faults in the logging subsystem.
• Logging: no need to initialize before the first logged method is hit.
• Caching: preventing concurrent execution (locking).
• Visual Studio tooling: support for the new CPS-based project systems.
• GDPR compliance: we no longer collect your name and email for trial, nor use unsecure HTTP, nor use non-resettable user id hashes. 

ASP.NET Web API Throttling handler, OWIN middleware and filter are designed to control the rate of requests that clients can make to a Web API based on IP address, client API key and request route.

public static void Register( HttpConfiguration config )
{
    config.MessageHandlers.Add( new ThrottlingHandler
                                {
                                    Policy = new ThrottlePolicy( perSecond: 1,
                                                                    perMinute: 20,
                                                                    perHour: 200,
                                                                    perDay: 1500,
                                                                    perWeek: 3000 )
                                                {
                                                    IpThrottling = true
                                                },
                                    Repository = new CacheRepository()
                                } );
}

In this series I answer various .NET questions. Some of them are asked during interviews, some of them I see on the internet, some of them are completely made up. The goal is to provide short answer with links to references if needed. This is by no means a .NET tutorial or experts reference, this is just a bunch of useful answers to refresh your knowledge. 

You can do custom routing based on subdomains using dynamic routes. In this episode we'll explore how to do that. 

In Chrome 80 and later, cookies will default to SameSite=Lax. This means that cookies will automatically be sent only in a first party context unless they opt-out by explicitly setting a directive of None.
But if you’re a web developer, you should start testing your sites and services now to help ensure a smooth transition. 

Here are some excellent one-page / single-page websites to check out. There are a variety of website types included in this showcase — online portfolios, restaurants, mobile apps, and more. I hope looking at these one-page sites will give you ideas and inspiration for your web design projects.

Improper Authentication and Session Management

Most web applications have an authentication module, and we should be careful when writing code for it. We could make mistakes like not removing the authentication cookies after a successful logout. This kind of mistake allows attackers to steal user credentials such as cookies and session values, and may result in attackers being able to access the complete application and cause major negative impacts.
