Hi,

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.

Can you please suggest how to get rid of this problem.

Is the unmanaged dll serializable? Are you using WCF?
