Use .NET Framework 4.5 dll in Framework 4.0 project
.net, .net-4.0, .net-4.5, compatibility
Solution
You can't use a 4.5 dll in a 4.0 project. Think about upgrading your 4.0 project or downgrading the 4.5 project. Upgrading will probably the easiest, because if the 4.5 is using 4.5 features (if not, why make it a 4.5 project...), you will have to rewrite them to 4.0.
Problem
I am working on a project which is build on dot net 4.0 and i have a need to use some .dll's which are released with dot net framework 4.5. Is there a way to include and use them on my project? If Yes then please suggest the way. Thanks in advance..
