C# 11 New Features

C# Features
C# 11

C# is an object-oriented, component-oriented programming language.C# provides language constructs to directly support these concepts, making C# a natural language in which to create and use software components.

Now .Net 7 Preview 1 was released on February 17,2022 and along with it, previewed some of the new features in C# 11.

You must set LangVersion to preview to enable these features. Any feature may change before its final release. These features may not all be released in C# 11. Some may remain in a preview phase for longer based on feedback on the feature.

Every developer can check them on their own in Visual Studio 2022 version 17.3 (some of those features are available in earlier VS versions – e.g., Visual Studio 17.1). New features can also be checked in the .NET 7 SDK preview format (available to download on the .NET platform).

  • Generic Attribute
  • NewLine in string Interpolation
  • Parameter null-checking
  • List and Slice Pattern

Generic attributes

C# version 11 has been equipped with a generic attribute feature. This allows you to create a generic class deriving a System.Attribute, which facilitates creating attributes requiring System.Type parameter. In earlier versions of C#, a developer had to construct a more complex solution of attributes with the Type parameter in the constructor.

NewLine in string Interpolation

String interpolation was introduced in C# 6 with Visual Studio 2015. String interpolation replaces String.Format(). The format of the interpolated string is a string inside double quotes preceded by $. Inside that string, you can pass the parameters or method executions in brackets {}.

In C# 11, string interpolation gets a small update – it allows you to contain new lines inside the formulas. Previously, some long formulas, containing LINQ queries might have been unreadable. But no more! With the next release of C#, we will be able to use new lines, and then, complex string interpolated formulas will look much better.

Parameter null-checking

They are putting this feature into this early preview to ensure we have time to get feedback. There have been discussions on a very succinct syntax vs. a more verbose one. We want to get customer feedback and from users that have had a chance to experiment with this feature.

List and Slice Pattern

Pattern match has been evolving over the past couple of versions of C# and it continues to do so in C# 11 as well. List Pattern and Slice Pattern are the new entrants in the pattern collections which are getting richer with each C# version.

  What is ChatGPT? ChatGPT   ( Chat Generative Pre-trained Transformer ) is an artificial-intelligence chatbot developed by San Francisco-based AI research company OpenAI. Released in November 2022, it can have conversations on topics from history to philosophy, generate lyrics in the style of Taylor Swift or Billy Joel, and suggest edits to computer programming code. ChatGPT is trained on a vast compilation of articles, websites and social-media posts scraped from the internet as well as real-time conversations—primarily in English—with human contractors hired by OpenAI. It learns to mimic the grammar and structure of the writing and reflects frequently-used phrases. Is AI going to replace jobs? As with every wave of automation technologies, the latest will likely have a significant impact on jobs and the future of work. Whereas blue-collar workers bore the brunt of earlier waves, generative AI will likely have a greater effect on white-collar professions. A 2019 study from the Brooki

Azure Cosmos DB

                 Azure Cosmos DB is a NoSQL data store. It is different from the traditional relational database where we have a table, and the table will have a fixed number of columns, and each row in the table should adhere to the scheme of the table. In the NoSQL database, you don't define any schema at all for the table, and each item or row within the table can have different values, or different schema itself. Database:  We can create one or more Azure Cosmos database under our account. A database is analogous to a namespace, and it is the unit of management for a set of Azure Cosmos containers. Cosmos Account:  the Azure Cosmos account is the basic unit of global distribution and high availability. For globally distributing our data and throughput across multiple Azure regions, we can add or remove Azure regions from our Azure Cosmos at any time.
