I am using DataTable.net editor for dotnet core with postgrsql

Npgsql 3.x removed support for writing a parameter with an IEnumerable value, use .ToList()/.ToArray() instead

    Thank you - I wasn't aware of that. I've filed a bug internally so we get it fixed for the next release.

    I've just been looking into this one and we actually use Npgsql 4.0.3 in our demo scripts and it appears to work okay.

    You mention Npgsql 3, but 4.0 was released in 2018.

    I realise this is an old post now, but using Npgsql 4.x should work no problem.

    If you add .TryCatch(false) just before the .Process(...) call does it tell you what line the error is happening on? Or is this a compile time error? In which case, does the compiler tell you the error?

    I don't understand why this would be happening unless Tortuga.Chain.PostgreSql is pulling in an old version?
