I would like to add a package, but I get the error: Install failed: Install failed Could not install package '<package name>'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.0', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.
This is ok. I have not checked the framework version.
It is a suggestion, can You mark the package, if it can be installed or not with the current framework version?
