Apps using ReflectASM

ReflectASM is a powerful and efficient open-source library designed to enhance the performance of .NET applications through optimized reflection techniques. This high-performance library leverages assembly generation to create fast reflection-based code, significantly reducing the overhead typically associated with traditional reflection methods in C# and other .NET languages. ReflectASM achieves this by dynamically generating and compiling IL code at runtime, resulting in near-native performance for reflection operations. One of the key features of ReflectASM is its ability to create fast property accessors and method invokers. These optimized accessors and invokers can be up to 20 times faster than standard reflection, making it an invaluable tool for developers working on performance-critical applications. The library is particularly useful in scenarios where frequent reflection operations are required, such as in object mapping, serialization, and dependency injection frameworks. ReflectASM is designed to be easy to integrate into existing projects, with a simple and intuitive API that allows developers to quickly replace standard reflection calls with their optimized counterparts. The library supports a wide range of .NET platforms, including .NET Framework, .NET Core, and .NET Standard, making it versatile and adaptable to various development environments. Another notable aspect of ReflectASM is its compatibility with AOT (Ahead-of-Time) compilation scenarios. This feature ensures that the library can be used in environments where JIT (Just-in-Time) compilation is not available or restricted, such as iOS development with Xamarin. This flexibility makes ReflectASM a valuable asset for cross-platform development projects. The library also provides excellent support for working with generic types and methods, allowing developers to maintain type safety while benefiting from the performance improvements offered by ReflectASM. This feature is particularly useful when dealing with complex object hierarchies or when implementing generic algorithms that rely heavily on reflection. ReflectASM incorporates various caching mechanisms to further optimize performance. These caches store generated accessors and invokers, reducing the need for repeated code generation and compilation. This approach not only improves the overall performance of the application but also helps to minimize memory usage over time. Security is a crucial consideration in ReflectASM's design. The library includes built-in safeguards to prevent unauthorized access to private members and respects the access modifiers defined in the original code. This ensures that developers can leverage the performance benefits of ReflectASM without compromising the integrity and security of their applications. For developers working on large-scale projects or high-traffic applications, ReflectASM offers significant advantages in terms of scalability. By reducing the overhead associated with reflection operations, the library helps to improve the overall responsiveness and throughput of applications, particularly under heavy load conditions.
