I created a project on Sharepoint 2010. I need a Third Part dll reference in order to solve a problem. After downloading the dll, putting it in the project, add the reference to this library and adding it to the package, I try do deploy the project.
I'm getting the following exception:
Error occurred in deployment step 'Add Solution': Could not load file or assembly or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
It seems like dll framework version is 4.0 or 4.5.
What shoud I do?
