JavaScript is a dynamically typed language which comes with great power of expression, but it also comes with almost no help from the compiler. For this reason we feel very strongly that any code written in JavaScript needs to come with a strong set of tests. We have built many features into Angular which make testing your Angular applications easy. With Angular, there is no excuse for not testing. 

• VS is more responsive when running Git operations.
• Debugging large solutions with /debug:fastlink PDBs is more robust. Changes in the PDB/DIA lead to reduced latency and a 30% reduction in heap memory consumption in the VS debugger that used to cause crashes.
• C++ compiler bugfixes:
  • Fix for the SSA optimizer incorrectly sinking a function call past a store to a variable used in a __finally handler.
  • Fix for the SSA optimizer sometimes incorrectly analyzing memory loads from locations with negative offsets.
  • Fix for the optimizer incorrectly transforming a pre-incremented loop into a post-incremented loop. This was found compiling the ICU project.
• Microsoft bumped up the Java™ Development Kit 8 to Update 172 (JDK version 8u172). 

یک نکته تکمیلی:

یکی از مشکلات استفاده از JSON.parse(JSON.stringify(originalObject)) برای کپی کردن آبجکت‌ها این است که از آبجکت‌های circular پشتیبانی نمیکند؛ به عنوان مثال کد ساختار زیر را در نظر بگیرید:

const a = { x: 20, date: new Date() };
a.c = a;

استفاده از JSON.parse... خطای زیر را صادر خواهد کرد:

یکی دیگر از مشکلات این است که برای پراپرتی‌هایی از نوع Date به صورت خودکار Date.prototype.toJSON صدا زده خواهد شد:

برای رفع این دست از مشکلات میتوانید از تابع توکار structuredClone استفاده کنید:

البته این تابع یکسری مشکلات هم دارد: توابع، کلاس‌ها، DOM قابل clone نیستند. 

One Blazor Template to Rule Them All in .NET 8

In .NET 8 there is a new project in town that unifies the developing experience between Blazor Server and Blazor Web Assembly application models. In this video we will go over the new template and how we can get started using it! 

The current process creates friction for users. Finding an OTP within an SMS message, then copying and pasting it to the form is cumbersome, lowering conversion rates in critical user journeys. Easing this has been a long standing request for the web from many of the largest global developers. Android has an API that does exactly this. So does iOS and Safari 

With .NET 6 previews starting right around the corner, it is time to start getting excited for the new .NET Multi-platform App UI (MAUI) that was announced at BUILD 2020. This year of .NET has a lot of amazing things for client application developers. Let’s review the highlights and set your expectations for the year ahead. 

Ah, yes, Vim, the powerful text-editor that is everywhere and a place where even the wisest can’t quit. You had to hear about it at least once. Or you might have considered learning or trying it. But why do it now?

It’s 2020, doesn’t everyone use VSCode already? Let’s dive in and figure why someone would still learn Vim.

The Windows Package Manager is a tool designed to help you quickly and easily discover and install those tools that make your PC environment special. By using the Windows Package Manager, from one command, you can install your favorite tool: winget install <tool> 

.NET Core 3.1 is a long-term supported (LTS) release (supported for at least 3 years). We recommend that you move any .NET Core 3.0 applications and environments to .NET Core 3.1 now. It’ll be an easy upgrade in most cases. 

The .NET team at Microsoft has been working in close collaboration with the gRPC team since November 2018 on a new fully managed implementation of gRPC for .NET Core.

We’re pleased to announce that grpc-dotnet is now available with .NET Core 3.0 today!
