ReSharper’s shell loading has been optimized to decrease Visual Studio’s startup time. Now it is faster, and we have mostly got rid of the Visual Studio yellow notification about the slowness of starting up ReSharper. There is still a yellow box about total u 

To get started with ASP.NET Core in .NET Core 3.0 Preview 9 install the .NET Core 3.0 Preview 9 SDK.

If you’re on Windows using Visual Studio, install the latest preview of Visual Studio 2019.

.NET Core 3.0 Preview 9 requires Visual Studio 2019 16.3 Preview 3 or later. 

Version 10.0.0 is here! This is a major release that spans the entire platform, including the framework, Angular Material, and the CLI. This release is smaller than typical; it has only been 4 months since we released version 9.0 of Angular. 

We are pleased to announce version 5.0.0 of Angular, pentagonal-donut. This is a major release containing new features and bugfixes. This release continues our focus on making Angular smaller, faster, and easier to use. 

Here’s a look at a handful of the changes since our last alpha:

• Overhauled spacing utilities to use a numerical tiering (to avoid confusion with grid tiers).
• Continued refactoring efforts to replace markup-specific selectors with classes across several components (including pagination, lists, and more). Still more to do here with additional components.
• Reverted media queries and grid containers from rems to pixels as viewports are not affected by font-size. See #17403 for details. We’ve got a ton of grid work left, too. Feel free to follow along with#18471.
• Reverted .0625rem width borders to 1px for more consistent component borders that avoid zoom and font-size bugs across browsers.
• Renamed .img-responsive to .img-fluid to avoid future confusion on the various responsive image solutions out there.
• Replaced ZeroClipboard with clipboard.js for Flash-independent copy buttons.
• Inputs and buttons now share the same border variable to ensure components are always sized similarly.
• Updated all pseudo-element selectors to use the spec’s preferred double colon (e.g., ::before as opposed to :before).
• Cards now have outline variants and mixins to support extending base classes further.
• Utility classes for floats and text alignment now have responsive ranges. This means we’ve dropped the non-responsive classes to avoid duplication.
• Added support for jQuery 2.
• And hundreds more Sass improvements, bug fixes, documentation updates, and more. 

• A bug is fixed in loop unroller which might lead to wrong condition codes being generated in the unrolled loop.
• Fixed a bug that caused ServiceHub.Host.CLR.x64 to stop working.
• Fixes issue in Chinese version of compiler errors C4533 and C2362 which resulted in incorrect order of string substitution for those languages.
• Improved stability of the Diagnostic Tools and Performance Profiler.
• Code generation problem causing crash with pure virtual destructor in const object
• Fixed a constant evaluation regression from 16.5 Preview 2
• Fixed an issue where MacOS couldn't be paired.
• Fixed an issue where the Diagnostic Tools while debugging and Performance Profiler fail to launch on XBox devices.
