Thank you for the details.
The additional information helped us reproduce the issue and it turns out that it appears only with .NET 3.5
assemblies. With assemblies from the same release in .NET 4.0
, the issue is not observed.
As for the project we sent you - it does not compile at your side, because it targets .NET
Having said this, we recommend upgrading to a higher version of .NET
and using Telerik UI for WPF
assemblies with version at least 4.0
- you can take a look at the minimum Development Environment requirements
for our WPF suite
Hope this helps.
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?
