.NET Core's migration story was a disaster; Microsoft's official guide basically recommended that you create a new project and copy files over one by one and hoped for the best. Many people didn't bother. Java 9 was also a mess; inching slightly closer to Scala and Kotlin (but not enough to make it worth going back to Java-the-language if you had already switched to one of those), while breaking a lot of existing code (a cardinal sin for a platform whose stability was its primary claim to fame). Many people didn't bother.
