Taking a lesson from scripting languages corresponding to Python and JavaScript, Microsoft has launched a file-based apps functionality for the C# language, which is meant to streamline C# growth.
Launched in .NET 10 Preview 4, the brand new function permits builders to run a stand-alone C# (.cs) file straight with the command, dotnet run app.cs. Builders now not have to create a challenge file or scaffold a whole software to check a take a look at snippet, run a fast script, or experiment with an concept, wrote Damian Edwards, principal architect at Microsoft, in a Might 28 weblog put up asserting the function. Beforehand, operating C# code utilizing the dotnet CLI has required a challenge construction that included a .csproj file. Builders can get began with the function by downloading .NET 10 Preview 4.
File-based apps decrease the entry barrier to making an attempt out C# and make the language a more-attractive alternative for studying, prototyping, and automation situations, Edwards mentioned. Builders get a fast begin whereas no challenge file is required, there may be “first-class” CLI integration, and the potential scales to actual functions. There is no such thing as a separate dialect or runtime; when a script grows up, it might probably evolve right into a full-fledged challenge utilizing the identical language, syntax, and instruments. With .NET 10 Preview 4, file-based apps additionally assist a set of file-level directives to declare packages, SDKs, and properties (that are saved in challenge recordsdata for challenge apps) with out leaving a .cs file.
