Why?

[bricelam]

Can't release an LTS of EF Core that depends on a non-LTS of SqlClient ☹

[bricelam]

dotnet/SqlClient#1103

[bricelam]

Further explanation: We don’t want to put customers in a position where most of their app has long-term support from Microsoft under the .NET 6.0 support policy, but their support policy for the SqlClient assembly has expired.

Apologies, while this PR appears ready to be merged, I've been configured to only merge when all checks have explicitly passed. The following integrations have not reported any progress on their checks and are blocking auto-merge:

1. Azure Pipelines

These integrations are possibly never going to report a check, and unblocking auto-merge likely requires a human being to update my configuration to exempt these integrations from requiring a passing check.

From the bot dev team

We've tried to tune the bot such that it posts a comment like this only when auto-merge is blocked for exceptional, non-intuitive reasons. When the bot's auto-merge capability is properly configured, auto-merge should operate as you would intuitively expect and you should not see any spurious comments.

Please reach out to us at fabricbotservices@microsoft.com to provide feedback if you believe you're seeing this comment appear spuriously. Please note that we usually are unable to update your bot configuration on your team's behalf, but we're happy to help you identify your bot admin.
