JazSharp is a unit testing framework for .NET that works very similar to Jasmine:
-
Tests are defined using Describe and It
-
Method calls can be replaced with spies allowing you to truly isolate the code you are testing
-
Full set of Assets (known as Expects) including ToHaveBeenCalledWith, ToEqual and ToContain which perform recursive comparisons
Today, we are happy to announce the release of Visual Studio 2015 RC.
This version includes many new features and updates, such as tools for

نکته تکمیلی
از Net 3. به بعد به جای واسط IHostingEnvironment از IHostEnvironment استفاده شود.

IHostingEnvironment is one of the most annoying interfaces in .NET Core 2.x, because it exists in two different namespaces, Microsoft.AspNetCore.Hosting and Microsoft.Extensions.Hosting . These are slightly different and are incompatible - one does not inherit from the other. 
یک نکته‌ی تکمیلی: فعال سازی Dot net core 3 در Visual Studio 2019
سپس تیک مربوط به Use preview of the .NET Core SDK را قرار دهید. چنانچه این گزینه را نداشتید از مسیر زیر استفاده کنید:
حال تیک مربوط به Use preview of the .NET Core SDK را بزنید.
وقتی Visual Studio 2019 را نصب میکنید به طور پیش فرض Core 2 را دارا هست اما نسخه dote net core 3 را ندارد. برای نصب dot net core 3 ابتدا SDK مربوطه را دانلود کنید. تا این لحظه آخرین نسخه dotnet-sdk-3.0.100-preview7-012821 می‌باشد. ممکن است برای شما نسخه جدیدتری آمده باشد. سپس آن را نصب کنید و چون نسخه preview هست باید در visual studio 2019 آن را فعال کنید. در نسخه‌های قدیمی‌تر ویژوال استدیو 2019 ابتدا از منوی Tools مسیر زیر را دنبال کنید:
Tools > Options > Project and Solutions > .Net Core

.NET MAUI Full Course : Cross Platform Development
.NET MAUI allows you to create multi-platform apps using one code base. That means you can develop for Android, iOS, macOS and of course Windows at the same time!
In this course I provide numerous examples on how to use all the tools MAUI provides. Check out the long table of contents below.
Bootstrap v5.1.2 is here with a handful of improvements across our components, plus a fix for an issue in another project that prevented our Sass from compiling properly. Keep reading for the highlights.
- VS is more responsive when running Git operations.
- Debugging large solutions with
/debug:fastlinkPDBs 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
__finallyhandler. - 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.
- Fix for the SSA optimizer incorrectly sinking a function call past a store to a variable used in a
- Microsoft bumped up the Java™ Development Kit 8 to Update 172 (JDK version 8u172).
