C# 14 breaking change heads up

[333fred]

Hey folks, as part of our smoke testing for .NET 10, we noticed that grandnode2 is affected by the breaking change in C# 14 around first-class spans. @jjonescz has a full writeup on the change here, and I've filed a bug on the MongoDB provider for the scenario here, but when you upgrade to .NET 10, at least some reaction to this will be needed, either to change your code to work around the issue as Jan described, or by upgrading to a version of the MongoDB driver that adapts to change. Otherwise, you will errors like System.NotSupportedException: 'Specified method is not supported.'.
