I am creating web service where I have added managed dll, which interns uses unmanaged static library. When I make a call from client till managed dll flow goes well, after that, when flow goes to unmanaged function, following execption occurs,

An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in WebDev.WebHost40.dll
Additional information: Exception has been thrown by the target of an invocation.

Is the unmanaged dll serializable? Are you using WCF?
