What is NProfiler?
NProfiler is a professional performance profiling tool designed for .NET applications. It enables developers to analyze method execution times, identify bottlenecks, and optimize code efficiency across various .NET frameworks and languages. The tool provides detailed insights into CPU usage, blocking operations, and exception handling to enhance application performance.
With features like overhead compensation for accurate measurements, integrated decompilation for third-party components, and support for multiple profiling modes, NProfiler delivers reliable performance data. Its intuitive interface includes timeline views, call trees, and line-level results, making it accessible for developers seeking to improve their .NET applications' speed and reliability.
Features
- Overhead Compensation: Delivers highly accurate timing data by accounting for profiler overhead
- Integrated Decompilation: Provides line-level timings even without source code for third-party components
- Multiple Profiling Modes: Supports executables, ASP.NET Core, IIS, Windows services, and attach to processes
- Intuitive User Interface: Includes timeline, call tree, method lists, and dark mode for ease of use
- Cross-Language Support: Profiles C#, VB.NET, and F# across .NET Framework, .NET Core, and .NET 5+
