I am using dot net framework (4.0) visual studio 2010 . and one of my friend gave me the project which he developed in .net framework 4.5 ( vs 2012 ) . And i am unable to open the project
. and the error i am getting is Unable to read the project file 'EssentialTools.Tests.csproj'.
one or more projects in solution is not correctly loaded ? How can i convert .net framework 4.5 to 4.0. And i have tried to change the target version in web.config to 4.0 but still it throws error ?????
