asp.net with unmanaged dataaccess dll

User_KOZE0Nov 1 2021

Hi team,

I'm porting old asp.net app from oracle clent 10.2.0 using Oracle.DataAccess.x86 to the 19c client. Trying to use Oracle.Data.Access.11.2.1.0_x64.1.0.0 dll and cannot make it working.
Getting runtime error:
System.BadImageFormatException: Could not load file or assembly 'Oracle.DataAccess' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Tried recompiling the whole solution for x64 - same error. I would really appreciate some guidance.

Jack
