Error when profiling: no mapping for DbType UInt64 to known SqlDbType

Hi,

Since today, I can no more use ANTS Profiler to profile my ASP.NET application. When I launch a profiling session, everything start like usual, but when I end the session by clicking on the stop button, the data loads and then an error message explain me that there is no mapping for DbType UInt64 to known SqlDbType.



I profiled my app using the 'run as 32-bits app' checked. Then I unchecked this option but the error message prompt again.

Can anyone help me with this issue? Thanks a lot

Generally speaking, although we do support MySQL queries, we unfortunately don't support (yet) queries that use unsigned integer query parameters. We've raised this as an internal issue to be investigated.

If nothing changed in the your database and application since a week ago, then I suspect something might have changed in the input data. One of the app's queries started sending an unsigned 64-bit integer to the database through a MySqlParameter. Though it is our bug, maybe you will be able to avoid the use of UInt64 until the issue is fixed on our side?

This issue has been fixed and is in the latest release (10.2.0).
