A C# Source Generator for generating C# reserved attributes with internal accessibility.
see also: https://github.com/ufcpp/InternalReservedAttributeContent
Some C# features depend on attributes and modifiers but these can be internal. For instance, you may get CS0518 "Predefined type 'System.Runtime.CompilerServices.IsExternalInit' is not defined or imported" errors when using records (C# 9.0 feature) and you can avoid this error by adding the IsExternalInit class internally in your project.
namespace System.Runtime.CompilerServices
{
internal sealed class IsExternalInit { }
}The InternalReservedAttributeGenerator automatically generates these attributes and modifiers:
- IsExternalInit for init-only properties / records
- ModuleInitializerAttribute for module initializers
- SkipLocalsInitAttribute for localsinit flag
- Attributes for null-state static analysis
