![]() ![]() The LibraryImport source generator is now available in a supported manner to all users. With this feature, types previously requiring specialized handling in the runtimes (for example, Span and ReadOnlySpan), can now be fully implemented in C#. There was extensive language design behind this much requested feature that users can read about: low-level struct improvements. NET 7 runtimes now have full support for ref fields within ByRefLike types (that is, ref struct). Low-level struct improvements: ref field support UnixFileMode mode = File.GetUnixFileMode("myFile") įile.SetUnixFileMode("myFile", UnixFileMode.UserRead | UnixFileMode.UserWrite | UnixFileMode.UserExecute) Ī big thank you goes out to a long-term contributor from Red Hat, who proposed, designed, and implemented this feature. Using FileStream myFile = new FileStream("myFile", options) UnixCreateMode = UnixFileMode.UserRead | UnixFileMode.UserWrite, Create a new file with specific permissions Usage // Create a new directory with specific permissionsĭirectory.CreateDirectory("myDirectory", UnixFileMode.UserRead | UnixFileMode.UserWrite | UnixFileMode.UserExecute) Note that when you use these, umask is still applied, as it would if you created the directory or file in your shell. There is also a new overload of Directory.CreateDirectory and a new property on FileStreamOptions to allow you to create a directory or file with a particular mode in one shot. As well as a new property on FileInfo and DirectoryInfo named UnixFileMode. In Preview 7, we introduced a new enum: public enum UnixFileModeĪnd APIs File.GetUnixFileMode and File.SetUnixFileMode that get and set the file mode on either a path or a handle (file descriptors). For example, on Ubuntu you may have to pinvoke to _xstat, on RedHat to stat, and so on. P/Invoking manually to syscalls isn’t always easy because some are exposed differently on different distros. NET had no built-in support for getting and setting Unix file permissions, which control which users can read, write, and execute files and directories. ![]() Var sortedDesc = data.OrderByDescending() Support for Unix file modes Previously, you had to call OrderBy/ OrderByDescending by referencing the own value. Note: This change does not introduce a new language feature to. System.Linq now has the methods Order and OrderDescending, which are there to order an IEnumerable according to T. Now, let’s get into some of the latest updates in this release. If you’re on macOS, we recommend using the latest Visual Studio 2022 for Mac preview. ![]() NET 7 with Visual Studio family products. ![]() We recommend you use the preview channel builds if you want to try. NET 7 Preview 7 has been tested with Visual Studio 17.4 Preview 1. NET 7 Preview 7, for Windows, macOS, and Linux. NET 7 includes improvements to System.LINQ, Unix file permissions, low-level structs, p/Invoke source generation, code generation, and websockets. NET Conf: Focus on MAUI that is live streaming now!
