The SDK itself is fully backwards compatible. Regardless of whether the runtime itself is LTS, barring workarounds for bugs there should be no need to pin SDKs. * dotnet command and it said that SDK 6 was needed Can you remember what you executed?

Are you pinning versions via global.json? I just accepted the update and let it run to completion smoothly. A short time later I ran a dotnet command and it said that SDK 6 was needed. I saw in Control Panel that only SDK 7 was installed, so I reinstalled 6 and I was back to normal. Strangely, a colleague did the same thing and didn't see that happen. No pinning anywhere. I'll revisit the pros and cons. Greg
