linq2db 3.0.0-preview.1 not working with .net core 3

Question

linq2db 3.0.0-preview.1 isn't working with .net core 3, showing error:

System.ArgumentException: 'UdtTypeName' is not a member of type System.Data.SqlClient.SqlParameter' (Parameter 'propertyOrFieldName') While the same thing works great on .net core 2.2

since the exact same code works in .net core 2.2, the question arises whether it currently works with .net core 3 or will have to wait a while. Regarding the possibility of linq2db working with .net core 3, I really did not find any information, which oddly enough, is unusual.

On github there is a closed problem with a similar error, but it seems that the problem is fixed, and in the code I do not use UdtType, and the error crashes with any action with the database context, even with a simple fetch

Is it possible to somehow make this work or will I have to wait for a new version of linq2db?

Answer 1

Could it be that you use System.Data.SqlClient < 4.5.0 as this property was added to SqlParameter in this version?

Update: as quick fix you can update dependency to 4.5.0 or higher, but it looks like you've hit preview1 issue
