Hybrid cache can use both memory cache and distributed cache, which can improve cache hit rate and reduce access to distributed cache, thereby improving performance. When getting data from the cache, it will first get the data from the memory cache, if there is no data in the memory cache, it will get the data from the distributed cache. When writing data to the cache, it writes data to both the in-memory cache and the distributed cache.

Primary constructors One major feature in C# 12 is primary constructors. A primary constructor is declared on the type declaration instead of inside the class body. Its parameters can be used directly in members. Record types public record Address(string FirstName, string LastName); Class types public class Person(string firstName, string lastName) { public override string ToString() { return $"{firstName},{lastName}"; } } public Person(string firstName) : this(firstName, "hello") { } Collection expressions C# 12 adds collection expressions for concise collection initialization. // Create an array: int[] a = [1, 2, 3, 4, 5, 6, 7, 8]; // Create a list: List<string> b = ["one", "two", "three"]; // Create a span Span<char> c = ['a', 'b', 'c', 'd', 'e', 'f', 'h', 'i']; // Create a jagged 2D array: int[][] twoD = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]; // Create a jagged 2D array from variables: int[] row0 = [1, 2, 3]; int[] row1 = [4, 5, 6]; int[] row2 = [7, 8, 9]; int[][] twoDFromVariables = [row0, row1, row2]; Range and index usage sequence[0] is the first element. ^n means counting from the end. For any number n, index ^n is equivalent to sequence.Length - n. ...
