When loading a project, an ArgumentOutOfRangeException exception is thrown while AllowCrossVersion is set to true, and we have a namespace that contains a Telerik string.

The workaround here would be to avoid using the Telerik string in your namespace, project, files.

Here is an example exception: Types 'Telerik.Windows.Diagrams.Core.SelectionMode' and 'System.Windows.Controls.SelectionMode' both use the XML type name, 'SelectionMode', from namespace ''. Use XML attributes to specify a unique XML name and/or namespace for the type.

As a workaround, you can exclude the property with the repeating name as demonstrated in Example 4 in the following article: Serialization Options

Add SaveToStorage method to the IsolatedStorageProvider that takes as parameters a list of the StorageIds to be saved.

Will be available in Q3 2015 Release.

A first chance exception of type System.IO.FileNotFoundException is thrown by the IsolatedStoragetProvider when calling its SaveToStorage() method. 

Note: the exception does not prevent the manager from saving the UI. To see the error you will need to enable the CLR exceptions from the Visual Studio's Debug-->Exceptions menu


Available in LIB version: 2015.1.1805

The XmlSerializer constructor generates a new assembly every time you save your layout and this causes performance and memory issues.
