Hi

I cannot Run my UWP app in release mode with  ".NET Native tool chain" enabled 

It fails on the Load function :
        Stream str = readStream.AsStream();
         sfdiagram.Load(str);


Exception thrown: 'System.Runtime.Serialization.InvalidDataContractException' in System.Private.DataContractSerialization.dll
An exception of type 'System.Runtime.Serialization.InvalidDataContractException' occurred in System.Private.DataContractSerialization.dll but was not handled in user code
Additional information: Type 'Syncfusion.UI.Xaml.Diagram.DiagramElementViewModel' cannot be serialized, serialization code for the type is missing. Consult the SDK documentation for adding it as a root serialization type.

Visual Studio Enterprise 2015 Update 3
Syncfusion 14.3.0.49

Hi Andreas, 
 
The reported issue can be resolved by assigning the position as zero to the Stream before Loading. We have provided code example to represent this. Please refer to the code example as below. 
 
Code Example: 
System.IO.MemoryStream str = new System.IO.MemoryStream(); 
 
str.Position = 0; 
diagram.Load(str); 
 
//Here,diagram is the instance of SfDiagram. 


We hope that , Charl also resolved the issue as we described above. 
 
Regards, 
Ranjitha A.
