## What it is
AsmDude2 is a Visual Studio 2022 extension providing assembly syntax highlighting, code completion, hover descriptions, and signature help for x86/x64 assembly files and the disassembly window. It is built on a Language Server Protocol backend and supports instruction sets including SSE, AVX, AVX2, and AVX-512.

## Use cases
- syntax highlighting for assembly files in Visual Studio
- code completion for x86 assembly mnemonics
- read and understand the disassembly window
- hover documentation for assembly instructions
- support for AVX-512 and AVX2 instruction sets
- assembly editing with code folding in VS2022

## When to choose
- you write or read x86/x64 assembly in Visual Studio 2022
- you need highlighting and completion for MASM or NASM files
- you want richer disassembly window readability

## When to avoid
- you use Visual Studio versions older than 2022
- you need the full feature set of the original AsmDude, some of which is not yet ported
- you work with non-x86 architectures like ARM
