Cannot set renamePsiElementProcessor in rider plugin

I use following code:

<extensions defaultExtensionNs="com.intellij">
    <renamePsiElementProcessor implementation="ro.idea.cs.RenameF"/>
...

and RenameF

class RenameF extends RenamePsiElementProcessor {
    @Override
    boolean canProcessElement(@NotNull PsiElement element) {
        return false
    }
}

I set breakpoint in "return false" and debug my plugin and rename a c# file, for ex My.cs to MyFile.cs, the debug session cannot stop in "return false" breakpoint.so how to define a renamePsiElementProcessor for rider in rider plugin
