- Arrays are not allowed as return types due to mutability; use IReadOnlyList<T> instead.
- Supported argument types include literals, collection initializers, expressions, const values, and enum members.
- Uses C# interceptors to replace method calls with pre-computed values at runtime.
- Requires .NET 8.0 or later and C# 12 or later for interceptors support.
- Methods must be static, the containing class must be partial, and arguments must be compile-time constant expressions.
- Error codes include issues like unsupported return types, compilation emit failures, and method execution failures.
