UserMode support will be removed starting 03/29/2022. The last version to support UserMode is e2f159f8f, UserMode please use VC-LTL5

ucxxrt is a open source rutime library which based on MSVC.The highlight of this project is that it can be used in kernel-mode drivers.
It gives you the same experience as user-mode application development in C++ when developing kernel-mode drivers.

Before ucxxrt was born,in order to use C++ on kernel-mode drivers, I use (KTL、ustd、...).

But there are several problems，like it isn't support C++ exception and it cost much time on implementing new features which provided by the latest ISO,then ucxxrt was born.

• In kernel-mode driver mode,forced disable kernel-mode flag by using property sheet ,it makes the compiler support C++ exceptions.
• Implement the exception functions such as throw、catch. Simulated the exception dispatcher in throw.

Kernel-mode：

• support new/delete operators.
• support C++ exception (/EHsc).
• support SAFESEH、GS (Buffer Security Check).
• support STL (not fully).
• support static objects.

List of features that are not supported at this time↓

IDE：Visual Studio 2019 or higher

• git clone https://github.com/MiroKaku/ucxxrt.git
• Open ucxxrt.sln and compile

1. Copy ucxxrt/ucxxrt forder to you project directory.
2. Add the property sheet ucxxrt.props to yor project.

!! note：Rename DriverEntry to DriverMain

• Microsoft's C++ Standard Library
• Chuyu-Team/VC-LTL
• RetrievAL
