Well this is embarrassing; something completely unexpected happened. I don’t know what, but if you could report it, we can try to take a look.

Please include any information you think might be relevant to … whatever it says happened.

Things that might matter:

• what exactly did the message say?
• anything unusual in your code?
• what library versions of Dapper / Dapper.AOT / Dapper.Advisor are you using?
• what runtime (.NET 7, etc) are you using?
• what build SDK are you using? (dotnet --version)
• are you using an IDE (if so: which?) or the command-line?
• what operating system are you using?
