.NET 7 API diff
summary
A concise tour of concrete .NET 7 changes: Generic Math enables one generic numeric algorithm (example: a stack‑allocated, SIMD‑vectorized sum) and the BCL replaces many type-specific paths, cutting LINQ Min from ~32 ns and 32 B allocations to 5 ns and zero allocs. New source generators appear for Regex source generator (and non‑backtracking engine), JavaScript interop and native library import; demos include Blazor JS calls and AOT‑friendly generated marshalling. Also: polymorphic System.Text.Json, DbDataSource, TAR support, ReadLinesAsync and GetTempDirectory.
