Microsoft gives sneak peek at C# 11 features in latest Visual Studio update

In Microsoft’s Visual Studio 17.1, users will get a sneak peek at features coming to C# 11. These features will also be available in .NET SDK 6.0.200. 

A feature available in early preview is parameter null checking, which verifies at runtime if a null has been passed to code. This is separate from Nullable Reference Types (NRT), which identifies at design time if a null is possible.

Another new addition to the language is the ability to allow newlines in holes in non-verbatim interpolated strings. Holes, or interpolation expressions, are contained inside curly braces and supply runtime values. Previously newlines were allowed in verbatim interpolated strings, but in non-verbatim strings escapes, like \r or \n, were required instead.  

C# 11 will also include list patterns, which allows developers to match elements against lists and arrays. In addition, developers will be able to include a slice pattern to match zero or more elements. List patterns work with types that are countable or indexable, while slice patterns work with types that are countable or sliceable. 

Microsoft recommends users play around with these preview features, and can submit feedback in the C# repo on GitHub.

2022: The year of hybrid work

Remote work was once considered a luxury to many, but in 2020, it became a necessity for a large portion of the workforce, as the scary and unknown COVID-19 virus sickened and even took the lives of so many people around the world.  Some workers were able to thrive in a remote setting, while others felt isolated and struggled to keep up a balance between their work and home lives. Last year saw the availability of life-saving vaccines, so companies were able to start having the conversation about what to do next. Should they keep everyone remote? Should they go back to working in the office full time? Or should they do something in between? Enter hybrid work, which offers a mix of the two. A Fall 2021 study conducted by Google revealed that over 75% of survey respondents expect hybrid work to become a standard practice within their organization within the next three years.  Thus, two years after the world abruptly shifted to widespread adoption of remote work, we are dec...
