I'm in the long process of upgrading my project from Q1 2010 to Q1 2011, and am running into the following error with a form that uses the Scheduler:

Error 1 Type  in the data at line 152, position 5, cannot be loaded because it threw the following exception during construction: Could not load file or assembly 'Telerik.WinControls.Scheduler, Version=2010.1.10.409, Culture=neutral, PublicKeyToken=5bb2a467cbec794e' or one of its dependencies. The system cannot find the file specified.

For some reason, it's looking for the previous version of the control even though the assemblies (including Telerik,WinControls.Scheduler) are all the Q1 '11 versions.  This seems to be the only Telerik control that's having this type of issue with the upgrade.  What is the issue?

Hello Jeremy,

We had a known issue in the previous versions of RadControls for WinForms which was serializing the version of the SchedulerBindingDataSource in the resx files of the forms. This issue is addressed in our latest version, but when you update from an older version that has the issue, you should delete the serialized code manually. So, please check which are the resx files that cause the error and delete the entries similar to the entry below:

<data name="SchedulerBindingDataSource1.EventProvider.IsMasterEventIdCallback" mimetype="application/x-microsoft.net.object.binary.base64">
