We tried upgrading the VS 2010 Sharepoint farm solution to VS 2015 but not asking popup to upgrade the solution automatically.
Earlier we have seen message asking to upgrade solution.
We have tried in my local machines.
I have tried changing the framwork manually to 4.5 in the csproj file and reopened the project but couldn't help.Also tried uninstalling and reinstalling the softwares couldn't help to fix the issue.
Please suggest
