I am using YAF version 2.2.3 which has its source code in .Net 4.0.
Question: Can I safely change the Build to 4.7.2 for all projects in the source code for YAF? Or is there some dependency on .Net 4.0 in YAF 2.2.3 version?
In theory it should work. But upgrading yaf first would be the better solution!
