VMAware C# 🔍

Probably Not gonna update and maintain csharp version for obvious reason Simple, fast VM detection library for C# / .NET — no false positives!

Features

✅ No Hyper-V False Positives - Won't flag Windows hosts with Hyper-V enabled
✅ Simple API - Just 3 functions: Detect(), Percentage(), Brand()
✅ Fast - Cached results, runs detection once
✅ Modern - Works with .NET 6.0+
✅ Single File - Just copy VMAware.cs into your project

Quick Start

using VMDetection;

// Check if running in VM
if (VMAware.Detect())
{
    Console.WriteLine("Running in a VM!");
}

// Get confidence (0-100%)
int confidence = VMAware.Percentage();

// Get VM brand name ("VMware", "VirtualBox", etc.)
string brand = VMAware.Brand();

Detected VMs

Brand	Detection
VMware	Registry, WMI, files, drivers, MAC
VirtualBox	Registry, WMI, files, drivers, MAC
QEMU/KVM	Registry, WMI, disk serial, VirtIO
Xen	WMI, BIOS, MAC
Parallels	Registry, WMI, processes
Sandboxie	DLL, processes
Wine	ntdll export
Cuckoo	Files, pipes
AWS	BIOS vendor
Google Cloud	BIOS vendor
Azure	BIOS vendor

Why No Hyper-V Detection?

Windows 10/11 with Hyper-V enabled shows hypervisor signatures even on bare metal. This causes false positives. We skip these checks to ensure reliability.

If you NEED Hyper-V detection, check this manually:

// Only use if you're sure you're not on a Windows host with Hyper-V enabled!
bool hyperVGuest = Registry.LocalMachine
    .OpenSubKey(@"SOFTWARE\Microsoft\Virtual Machine\Guest\Parameters") != null;

Installation

Option 1: Copy the file

Just copy VMAware.cs into your project. Done!

Option 2: Build as DLL

dotnet build -c Release

Option 3: NuGet (coming soon)

Install-Package VMAware
