I can understand the problem now. From now on, you should expect the version of the DPL libraries - that is the following:
to be slightly different than the version of the other WPF libraries.
We decided that the change is too small (and kind of internal) to be included in the release notes, but looking at your scenario I consider this decision wrong. We will carefully document and include in release notes any subsequent changes in the assembly versioning.
To this particular case, I guess you could add two different variables - TelerikVersion, and TelerikDplVersion, and use the latter only for references to the aforementioned assemblies.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
