Union types in C# | DEM304
C# 15, shipping November, adds its own 'Goldilocks' version of union types to the language.
“we're just going to show you how unions should be.”
C# lead designer Matt Torus and engineer Dustin Campbell demoed union (discriminated union) types coming to C# 15 in November, already available in preview. This is a general programming language feature with no meaningful AI industry signal, relevant mainly to .NET developers rather than AI conference intelligence.
