Welcome to this short introduction to Blazor! This new Microsoft framework uses a unique approach to leverage your existing C# and .NET skills to create single-page applications running in web browsers. The technology that makes this possible is called WebAssembly, an open standard supported directly by current browsers on desktop and mobile platforms. You write C# and Razor code instead of JavaScript, and the compiled app runs natively on the client.

Third Party Site Cookies

In August 2020, Google announced their 'Privacy Sandbox' initiative, which aims to preserve and protect user's privacy. The cookie processing change is part of this initiative. An official  blog post sheds some light on it.

Google will drop support for third-party cookies in the Chrome browser in two years. Also, the company will start limiting cross-site tracking by enforcing its new SameSite rules . This has already happened in Chrome 80.

The SameSite-by-default and SameSite=None-requires-Secure behaviors will begin rolling out to Chrome 80 Stable for an initial limited population starting the week of February 17, 2020. 

5 Basic REST API Design Guidelines  

We’re excited to announce the release of .NET Core 3.0. It includes many improvements, including adding Windows Forms and WPF, adding new JSON APIs, support for ARM64 and improving performance across the board. C# 8 is also part of this release, which includes nullable, async streams, and more patterns. F# 4.7 is included, and focused on relaxing syntax and targeting .NET Standard 2.0. You can start updating existing projects to target .NET Core 3.0 today. The release is compatible with previous versions, making updating easy. 

Over five years ago I released MvcFlash, and soon after I released the second iteration MvcFlash2. Don't let the terrible naming and versioning fool you, this is one of my favorite creations. As ASP.NET 5 starts to take root and MVC 6 blossoms, I begin to feel more confident about creating the next version of MvcFlash. Honestly, I can't see developing an MVC application without it. Before I do, I thought I would muse about the possible challenges ahead. 

A Second Set of Bug Fixes: ReSharper 2023.2.2 and Rider 2023.2.2 Are Here! 

As we all probably already know, unlike Angular, where we already have a predefined way of structuring files, in React, that burden, or gift, depending on how you look at it — is bestowed upon us, the valiant developers. 

public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            ConfigureAuth(app);

                .HybridHttpOrThreadLocalScoped()
                .Use(() => appBuilder.GetDataProtectionProvider()));

            appBuilder.CreatePerOwinContext(
                () => ProjectObjectFactory.Container.GetInstance<ApplicationUserManager>());

            //appBuilder.UseTwoFactorSignInCookie(DefaultAuthenticationTypes.TwoFactorCookie, TimeSpan.FromMinutes(5));

            // Enables the application to remember the second login verification factor such as phone or email.
            // Once you check this option, your second step of verification during the login process will be remembered on the device where you logged in from.
            // This is similar to the RememberMe option when you log in.
            // appBuilder.UseTwoFactorRememberBrowserCookie(DefaultAuthenticationTypes.TwoFactorRememberBrowserCookie);
