Threading issue with COM Wrapper object

[Brian]

I have run into an issue with a web service I am working on that uses
an object defined in a COM Wrapper. There can be only once instance
of this object initialized at a time on the system, which is naturally
causing problems in ASP.NET 2.0 Web Service.
How does one go about managing this type of resource? Is it possible
to create an instance of an object that is shared across all the
threads created by multiple users hitting a web service? How does one
handle the process of initializing/disposing of such an object?
I'm a bit new to Web Services, so I really would appreciate any help
available.

I wouldn't host the wrapper in ASP.NET, for reasons you've already seen.
Instead, host it inside of a Windows Service, and use .NET remoting between
the Web Service and the Windows Service.

Can't the wrapper be hosted in ASP.NET by using the Singleton pattern
for implementation and keeping the object in the Application or Cache
object depending on the requirements?

That's an interesting idea, Latish. I had the singleton pattern set
up, but was unsure how to proceed. I hadn't heard of the Application
or Cache until now, so I will be doing some research on it. Does
anyone else know if this is an effective option?
