c# - .net Frameworks compatibility -


i create new application in framework 4.5 , have older application created in 1.1 framework , want call form exist in new application old 1 . try load executable application file using assembly class , assembly.loadfrom() used before , works fine between 2 different application, have same frameworks , exception thrown assembly invalid question it's possible call new assembly older 1 thank you

well, if old application has been loaded using older version of .net doesn't support newer assembly, no. it's bit trying run 64-bit binary on 32-bit operating system.

the simplest solution rebuild old application target .net 4.5 instead.
