Microsoft* Compatibility

This content is specific to C++; it does not apply to
DPC++
.
The
Intel® oneAPI
DPC++/C++
 Compiler
 is fully source- and binary-compatible (native code only) with Microsoft Visual C++* (MSVC). You can debug binaries built with the
Intel oneAPI
DPC++/C++
 Compiler
 from within the Microsoft Visual Studio* environment.
The compiler supports security checks with the /GS option. You can control this option in the Microsoft Visual Studio IDE by using
C/C++
Code Generation
Buffer Security Check
.

Microsoft Visual Studio Integration

The compiler is compatible with Microsoft Visual Studio 2017 and 2019 projects.
Support for Microsoft Visual Studio 2017 is deprecated as of the Intel® oneAPI 2022.1 release, and will be removed in a future release.
The compiler only supports native C++ project types provided by Microsoft Visual Studio development environment. The project types with .NET* attributes such as the ones below, cannot be converted to an Intel C++ project:
  • Empty Project (.NET)
  • Class Library (.NET)
  • Console Application (.NET)
  • Windows Control Library (.NET)
  • Windows Forms Application (.NET)
  • Windows Service (.NET)

Mixing Managed and Unmanaged Code

If you use the managed extensions to the C++ language in Microsoft Visual Studio .NET, you can use the compiler for your non-managed code for better application performance. Make sure managed keywords do not appear in your non-managed code.
For information on how to mix managed and unmanaged code, refer to the article, An Overview of Managed/Unmanaged Code Interoperability, on the Microsoft Web site.
