Feature requires a newer Dapper

Some Dapper.AOT features work by calling into APIs that were added to Dapper itself for the purpose - for example, DynamicParameters support delegates to the bag’s own AddParameters(IDbCommand) overload. Dapper.AOT feature-detects these APIs on the Dapper version your project actually references: when the API is present the feature lights up, and when it is not, the call-site is left on vanilla Dapper and this message tells you exactly which API was missing - rather than generating code that cannot compile.

Note that “left on vanilla Dapper” means reflection at runtime: fine under JIT, but it will not work under native AOT. To enable the feature, update the Dapper package to a version that includes the named API.
