I would like to create a readonly dependency property which allows me to attach a binding with the mode "OneWayToSource".

I think this is a severe bug. The workarounds, if at all applicable, are quite verbose and accordingly error-prone and hard to debug, and probably not as performant as the direct solution. This is by far more than syntactic sugar.

Why can't we vote this up? There is no reason for this error except for overzealous property checking on the binding operations. There is no reason at all that XAML can't support OnWayToSource on read-only properties and there are so many instances where a developer needs to do this that we end up badly hacking the XAML language in order to get around it.

+1, please don't disable voting. Is this because you can't fix the issue?

3 years latter and this is not fixed. So sad.
