How to allow overidding to dll of syncfusion in shard hosting server

[Muneeb Ahmed]

Hello Sir,

    I am stuck in an issue. I have a diagram web control and to use this diagram web control i have added Following 5 dlls. 

<add assembly=Syncfusion.Shared.Web, Version=11.4400.0.26, Culture=neutral, PublicKeyToken=3D67ED1F87D44">

<add assembly="Syncfusion.Core, Version=11.4400.0.26, Culture=neutral, PublicKeyToken=632609B4D040F6B4" />

<add assembly="Syncfusion.Shared.Base, Version=11.4400.0.26, Culture=neutral, PublicKeyToken=3D67ED1F87D44C89" />

<add assembly="Syncfusion.Diagram.Base, Version=11.4400.0.26, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" />

<add assembly="Syncfusion.Chart.Web, Version=11.4400.0.26, Culture=neutral, PublicKeyToken=3D67ED1F87D44C89" />

<add assembly="Syncfusion.Chart.Base, Version=11.4400.0.26, Culture=neutral, PublicKeyToken=3D67ED1F87D44C89" />

<add assembly="Syncfusion.Tools.Web, Version=11.4400.0.26, Culture=neutral, PublicKeyToken=3D67ED1F87D44C89" />

<add assembly="Syncfusion.Diagram.Web, Version=11.4400.0.26, Culture=neutral, PublicKeyToken=3D67ED1F87D44C89" />

All these runs very well on my localHost but as i put it on hosting server it gives me the following error

: Inheritance security rules violated while overriding member: 'Syncfusion.Windows.Forms.Diagram.Model.System.Runtime.Serialization.ISerializable.GetObjectData(System.Runtime.Serialization.SerializationInfo, System.Runtime.Serialization.StreamingContext)'. Security accessibility of the overriding method must match the security accessibility of the method being overriden.

Source Error: 

Line 29:                                 
Line 30:                              
Line 31:                                     <syncfusion:diagramwebcontrol id="DiagramWebControl1" runat="server" 

Can you tell me what is the problem. I have shared window hosting

Hi Muneeb,

 

Thanks for your update.

 

It seems the reported issue to be the security related issue and it is due to the medium trust level of ASP.NET web-application requires the application’s code to be security transparent. The problem is that GetObjectData() method required to implement ISearializable interface which is marked with a SecurityCritical attribute, and it "breaks" the transparency for the whole assembly. We suggest you to add the below attributes to the Assembly.info file of your project.

 

Here is the code:

[assembly: SecurityRules(SecurityRuleSet.Level1)]

[assembly: AllowPartiallyTrustedCallers]

 

Please let us know if you have any queries.
