Difference between C++ CLI and C++/CX

C++ CLI and C++/CX are extensions of the C++ programming language, which enables interoperability with the. NET framework. However, they share common properties in their design, usage, and target environment. This article explains both technologies in detail and provides a comparative analysis in tabular format.

What is the C++/CLI?

Common Language Infrastructure C++/CLI is the Microsoft language specification that extends the use of C++ by allowing this type to work with .NET smoothly. Its existence enables developers to take advantage of C++ while building up the applications and still be in a position to maintain the high performance associated with native C++. C++/CLI allows developers to bridge managed and unmanaged code because it has facilitated the ability of developers to use existing libraries in a C++ project within the context of .NET.

Key Features:

Several key features of C++/CLI are as follows:

• Managed Code: C++/CLI enables developers to write managed code that runs on the.NET Common Language Runtime (CLR). This results in the benefits of features such as garbage collection, type safety, and security.
• Interoperability with .NET: The primary use of C++/CLI is to create .NET applications or to wrap existing native C++ libraries so they can be called from C# or VB.NET.
• Syntax Extension: There are additional keywords and syntax to support managed types.
• Performance: High-performance application with native code while still staying within the .NET ecosystem.
• Tooling Support: It has powerful support in most IDEs, including Visual Studio, along with debugging and project management tools.
• Application and Legacy Integration: Use Cases Integration of legacy C++ code with new .NET-enabled elements, Performance-intensive applications, and Native component development can be used side-by-side with .NET features. Component development developer-written reusable components can be utilized by other .NET applications.

What is the C++/CX?

C++/CX (C++ Component Extensions) is another extension of Microsoft C++, focusing mainly on the Windows Runtime (WinRT) platform. C++/CX is primarily used for developing Windows store applications and components that can be used in a Windows environment, especially for Universal Windows Platform (UWP) applications.

Key Features:

Several key features of C++/CX are as follows:

• Windows Runtime Support: C++/CX is designed to work with the Windows runtime, which enables developers to create applications that run across different Windows devices.
• Simplified Syntax: The new syntax of C++/CX allows developers to work more easily with Windows runtime components by using keywords like ref class, ref struct, and ^ (handle) for managed references.
• Asynchronous Programming: C++/CX supports asynchronous programming models that help developers write applications more responsive.
• Direct Integration with XAML: It enables developers to design UI using XAML while reducing the distance between C++ and the declarative model of UI in Windows.
• Component-Oriented: This design focuses more on building Windows components that can be reused in various Windows applications and devices.

Use Cases:

Several use cases of C++/CX are as follows:

• UWP Application Development: Building an application targeting the universal windows platform is ideal when using C++/CX.
• Game Development: Game developers can use C++/CX for performance-critical game components, but integrate with Windows APIs.
• Windows Desktop Applications: Developers can use WinRT for building modern desktop applications.

Key differences between C++ CLI and C++/CX:

There are several key differences between C++ CLI and C++/CX. Some main differences are as follows:

Conclusion:

In conclusion, C++/CLI and C++/CX are extensions of C++ designed for different ecosystems, each with special strengths. It excels in bridging native C++ with .NET Framework hence, enabling developers to work in managed and unmanaged code environments and ensuring high-performance applications while outlining the features of .NET such as garbage collection and type safety. C++/CX has been optimized for Windows Runtime (WinRT) and Universal Windows Platform (UWP) development by providing simplified syntax, asynchronous programming, and tight integration with XAML for modern designing of Windows apps. While C++/CLI could be a good fit to integrate legacy code and .NET interoperability, C++/CX focus on responsiveness and building reusable components in Windows devices. The choice lies in whether .NET or modern Windows applications.
