I have client requirement to call windows Azura hosted webservice by passing SAS token through the CRM plugin. For this we have to use “Microsoft.ServiceBus.dll” for communication with Microsoft Azure Service Bus.

In solution I used the ILmerge tool to merge two DLLS i.e. plugin DLL and Microsoft.ServiceBus.dll, after registering the plugin I am getting following run time error:

Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=8.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: Unexpected exception from plug-in (Execute): XXXX.CRM.Core.Plugins.ERPIntegrationPlugin: System.TypeLoadException: Inheritance security rules violated while overriding member: 'Microsoft.ServiceBus.AuthorizationFailedException.GetObjectData(System.Runtime.Serialization.SerializationInfo, System.Runtime.Serialization.StreamingContext)'.

Hi Gayan,

Are the two assemblies targeting different .NET versions? I found some issues incorrect use of ILMerge with assemblies of different target .NET versions.

The solutions in below articles might be useful to find a clue.

The issue was related to the DLL not being on the same ,net framework. Once this was changed all worked as expected.

Im getting similar error. Below is the exception showing in notification it self

inheritance security rules violated while overriding member: 'Microsoft.IdentityModel.ClaimsIdentity.System.Runtime.Serialization.Iserializable.GetObjectData(System.Runtime.Serialization.Serialization.SerializationInfo,System.Runtime.Serialization.StreamingContext)'.Security accessibility of the overriding method must match the security accessibility of the method being overriden.

Any help on this is appreciated.
