.NET 7 Native AOT is a big step forward in a long line of approaches to deploying .NET applications natively. It does away with IL and JIT at runtime entirely. Introduced in .NET 7, this improvement is particularly significant for running .NET applications in serverless functions. This new deployment option eliminates the cold start issue, which has been a persistent problem for .NET on serverless platforms like AWS Lambda and Azure Functions. With Native AOT, you can generate a smaller deployable binary than previous methods, resulting in faster cold start times. AWS has officially embraced Native AOT, supporting it with their Amazon Lambda Tools. This new deployment option brings .NET 7 on par with TypeScript/JavaScript in terms of cold start times, making it a viable option for organizations with a largely .NET-oriented infrastructure.
