Here is the "STUPID" scenario i came across,Following is the problem i had
I had one folder in my computer and it had two different version of dlls,My project already had reference of one of the dll,But now i wanted the reference of other dll,I simply deleted the old reference and tried to add new reference of the other file by selecting it,It was added but was showing old version when i tried to see its property ,I tried multiple times with multiple ways but no luck
First just check out the folder structure i had in my project,Here "Dlls" is the folder from which i wanted to add another file
You can see the "Dlls" folder is included in the project, And thanks to "Mr. Zakir Rana", One of project partner who insisted me to try excluding this folder and adding reference, It sounded foolish to me as its physical folder after all no matter if it is included or not,But i was surprised as soon as i excluded the folder,And it started taking new reference !!!
