Problem

Image not saving / updating / uploading properly in Oracle Database using Entity Framework / EF Core in BLOB / CLOB field using Oracle.EntityFrameworkCore provider.

Solution

Oracle BLOB / CLOB has by-default restriction of 2000 bytes in Oracle.EntitiyFrameworkCore provider. Due to this reason it trims the larger image bytes array to 2000 bytes and store in database without giving any error. As a result image not appear properly when retrieved.

To overcome this issue, an attribute is provided by Entity Framework which increases its capability of accepting large sized images. MaxSize attribute is available in Data Annotations assembly which helps to solve this problem.

Hope your problem is solved. Happy Coding!!!
