When I launched FenixKit a couple of weeks ago it was .NET 8 only. A few people asked about .NET 10 support almost immediately, which made sense - it just shipped.
All four kits now support both .NET 8 and .NET 10. Same price either way - at checkout you pick the runtime you want and get that ZIP.
Nothing else changed in the kits themselves. If you already bought one and want the .NET 10 version, reach out and I will sort it out.
