Event-Exception: "Microsoft.Data.SqlClient.WriteCommandBefore"

[AndrewP-GH]

We have netcoreapp3.1 app and Azure SQL DB and after we have added this package (v0.7.1) for tracing via .AddOpenTracing() method, we have this warning in logs:

SourceContext: OpenTracing.Contrib.NetCore.MicrosoftSqlClient.MicrosoftSqlClientDiagnostics
Exception.ClassName: System.InvalidCastException
Exception.Message: Unable to cast object of type

I suggest that this unexpected field in the anonymous object is Statistics, but I don't understand how this can happen. Any ideas?
