Hi All,
I have a class A which is derived from ServicesComponent to participate in automatic transaction with falg Transaction.Required. Class A is exposed to client through remoting on Http channal hosting into IIS.
There is a class B which is also available through remoting hosted on IIS on the same URI. B creates new of A inside a function. It succeed and able to create instance of A inside B first time. But it failes in 2nd attempt when we retry to create the instance of A inside B. But if we restart the IIS then we are able to create instance of A first time.
Instance of Class B is created from a script written inside the MS exchange server.
Please help us to find the reason behind it.
exact exception which we had traced is:
"An error occured: Unable to cast object of type
Hclt.HydraPlatform.CoreServices.ServerSOAPBinary.A dministration.MaintainServerService to type
