WhatArch
A .NET tool for Windows that detects the target architecture of native binaries and .NET assemblies.
Features
- Detects native binary architectures: x86, x64, ARM64, ARM
- Identifies .NET assembly configurations: AnyCPU (.NET), AnyCPU (.NET - 32-bit preferred), x86 (.NET), x64 (.NET), ARM64 (.NET)
- Simple, script-friendly output
- No external dependencies - parses PE headers directly
Requirements
- Windows (PE files are Windows-specific)
- .NET 10 SDK
Installation
dotnet tool install --global WhatArch
Update the tool
dotnet tool update --global WhatArch
Usage
whatarch <path-to-binary>
Examples
# Native binaries (by name - searches PATH, adds .exe automatically on Windows)
whatarch notepad
> ARM64
whatarch cmd
> x64
# Native binaries (by path)
whatarch C:\Windows\System32\kernel32.dll
> x64
whatarch C:\Windows\SysWOW64\kernel32.dll
> x86
# .NET assemblies
whatarch MyApp.dll
> AnyCPU (.NET)
whatarch MyApp.x64.dll
> x64 (.NET)
Exit Codes
| Code | Meaning |
|---|---|
| 0 | Success |
| 1 | Error (file not found, invalid PE, etc.) |
How It Works
WhatArch reads the PE (Portable Executable) file headers to determine the target architecture. For .NET assemblies, it also examines the CLR header and CorFlags to distinguish between AnyCPU and platform-specific builds.
