Building Lambda functions with C#
The following sections explain how common programming patterns and core concepts apply when authoring Lambda function code in C#.
You can run your .NET application in Lambda using the managed .NET 6 or .NET 8 runtimes, a custom runtime, or a container image. After your application code is compiled, you can deploy it to Lambda either as a .zip file or a container image.
Lambda provides the following runtimes for .NET languages:
