For .NET and cloud developers, we’ve focused on improving the inner-loop dev experience. New .http/.rest files make it easier to test and iterate on your APIs directly in Visual Studio, while improved Dev Tunnels help streamline the configuration and management of your webhooks. We’ve also made it easier than ever to deploy your ASP.NET apps to containers.

Game developers can now view properties from base classes modified in an Unreal Blueprint asset without leaving the IDE. Visual Studio has improved the cross-platform development experience with a new remote file explorer, Linux Console output to the Integrated Terminal window, dev container improvements, and more.

Beyond individuals, Visual Studio also has new features to better support dev teams at scale, with exportable configuration files and a persistent update toggle helping ensure everyone on your team is working from the latest version of the tool.

This blog covers several of the top new features in Visual Studio 17.5—to see some in action, watch the Visual Studio 17.5 release video. As always lot of these features come straight from your feedback and suggestions. Your feedback is critical to help us make Visual Studio the best tool it can be! 

Let’s get a look at what 4.1 has in store for us!
- Template Literal Types
- Key Remapping in Mapped Types
- Recursive Conditional Types
- --noUncheckedIndexedAccess
- paths without baseUrl
- checkJs Implies allowJs
- React 17 JSX Factories
- Editor Support for the JSDoc @see Tag
- Breaking Changes

Ionic vs React Native – What is the best choice for your mobile app? 

WinML is a high-performance, reliable API for deploying hardware-accelerated ML (Machine Learning) inferences on Windows devices. Since its introduction, many developers started using this technology to develop UWP applications that leverage artificial intelligence. Throughout this blog post, we’ll understand how you can leverage WinML on a simple .NET5 Console app.
