This thread from (and 's follow-up) asks whether a UMDF driver can be written in C#. The short, practical answer is that UMDF drivers must be native code (C/C++). UMDF 1.x used a COM/C++ model; UMDF 2.x follows the WDF object model and is still native. Microsoft does not support implementing kernel- or user-mode drivers in managed languages because drivers require deterministic native behavior, tight control over memory and threading, and the driver toolchain and signing model expect native binaries.

Suggested alternatives and approach:

  1. Check whether an in-box class driver (HID, WinUSB, etc.) can be used. If so, a managed user-mode application can talk to the device via Win32 APIs, P/Invoke, or libraries (HID/USB wrappers), avoiding any driver work.
  2. If custom driver logic is required, implement a minimal native UMDF driver (C/C++) that exposes a stable IOCTL/device interface. Put higher-level logic in a C# service or application that uses DeviceIoControl or a thin native wrapper (C++/CLI or P/Invoke).
  3. Use the Windows Driver Kit (WDK) integrated with Visual Studio and the UMDF samples to learn the flow. Test drivers in a VM, follow driver signing requirements, and keep native/managed boundaries small.

Hosting the CLR inside a driver is unsupported and unsafe. The recommended pattern is native driver + managed user-mode component for the higher-level code.

You have to be more explicit and detailed in the description of your problem to get the best of assistance. Ok?

Hi Jamello,

I want to know is there any way to compile the UMDF driver using c#. If possible how to configure that in c# .net 2005. I dont want to use windbg or any other command line compilers.
