8.0.0

• [Breaking] Replaced (equality-based) Switch/Map with index-based ones.
  • Reason: perf + dozens of (generic) overloads make the methods difficult to use.
  • Migration from v7 to v8
• Adding sealed/readonly on class/struct is not necessary anymore, source gen takes this over
• Added discriminated unions (regular and ad hoc)
  • A union can be a struct or a ref struct.
  • Args of switch/map must be named.
  • Access modifier of union ctors are configurable + implicit conversions can be omitted.
• Smart enums, value object and unions can be nested
• [.NET 9] String-based smart enums are ISpanParsable
• [.NET 9] State and result of methods Switch/Map can be a ref struct
• Unions and value objects structs disallow default(T) and parameterless ctors by default. Value objects are configurable via AllowDefaultStructs.
  • Union structs throw InvalidOperationException if they are not initialized or initialized with default value
  • DefaultInstanceProperty is generated if AllowDefaultStructs is set to true
• Non-hardcoded method args are escaped by default
• EF value converter shouldn't do unnecessary round-trip conversion
• Renamed generic type parameter from TContext to TState
• Bugfix in analyzer regadring arrays
