Reporting - An exception may be thrown when loading layouts with binary serialized objects

What Changed

We changed the XtraReport.LoadLayout overloaded methods' behavior.
These methods throw an exception on an attempt to load a layout that includes untrusted binary serialized object(s).

Reasons for Change

This change is required to correctly handle untrusted layouts.

Impact on Existing Apps

If your application handles untrusted layouts, the LoadLayout methods throw an exception.

How to Update Existing Apps

Do either of the following if your layouts contain binary serialized objects:

• Remove unsafe binary serialized objects from your layouts.
• Reporting uses a safety mechanism for all deserialization operations to improve security. An exception is thrown if a layout attempts to load an unsafe type. Review all unsafe type exceptions. If you trust a certain type, use the following code to enable deserialization:

  C#
  DevExpress.Utils.DeserializationSettings.RegisterTrustedClass(typeof(CustomClass));  
  

  Visual Basic
  DevExpress.Utils.DeserializationSettings.RegisterTrustedClass(GetType(CustomClass))
