problem : have developed application in local machine heigher version of .net framework , running same on remote pc having lower version of.net framework.

note : if target application run on heigher version of .net framework wont run on lower versions.

solution : need target .net framework lower version available on remote pc run on remote pc.

step 1: right click on project - select properties

step 2: change target framework .net framework x.x .net framework x.y.

note : x.x heigher , x.y lower version available on remote pc or lower version.
