System.Configuration does not support config files for libraries.

[Bill McCormick]

<!-- When deploying the service library project, the content of the
config file must be added to the host's app.config file.
System.Configuration does not support config files for libraries. -->

I assume "libraries" here to mean DLL's. If that's the case, is there
any way to supply both ends of a service (client and host) with the code
for the class that describes the contact WITHOUT a duplication in
source code?

Thanks.

Bill,

I assume you are referring to WCF given the nature of your previous
post.

Assuming that, you are confusing the config file (which is just an XML
file with config info) with the assembly itself (the DLL). You can easily
distribute a DLL to both sides (client and server). It's the config file
you can't share (well, in WCF's case, you actually could assuming you had no
clients in the service, and no other services in the client).

Well, I'm referring to WCF in general. Thanks you.

Hi Bill,

Seems what you want to do is sharing some custom classes/types (defined in
a class library) between the WCF service and client application. For WCF
there is type sharing support. Here are two artifcles which has mentioned
some information on this;

Thanks Steven. I think that is indeed for what I'm looking. However, I
expected this to be a little more trivial that it appears to be.

I guess I'm now left with two nagging questions:

1. Why is type sharing frowned upon?

2. How can a client app be written, using intellisense, without type
sharing?


Thanks,

Bill

Thanks for your reply Bill,

As for the sharing type functionality, it is done by the WCF client proxy
generation process. As mentioned in the articles, the command svcutil.exe
can help do it via a command line option. While in Visual studio IDE, when
"Add service reference", you can click "Advanced" button to find the
sharing type option. So far this is the most interactive friendly means I
have found.

Thanks Steven, but I'm not sure if that really answers my questions:

1. What is the *argument* against type sharing?

2. What are the *alternatives* to type sharing?

However, I am happy to know that there's a "pointy-clicky" way to
generate a client proxy. But that leads me to an extension of my 2nd
question:

2a. Is a "client proxy" strictly required for type sharing?

Thanks for your reply Bill,

As you mentioned in first message that you want to reuse the same set of
custom classes(will be used as parameter or return value of WCF service
operation), then I suggest you the "sharing type" feature of WCF. That's
the means which can help you make the client generated WCF proxy reference
the existing classes (in the specified assembly) instead generate a new
copy of delegate classes.

For WCF service, using "client proxy" is the most convenient means to
consume service methods. If you do not use them, you'll need to manually
write the code to call the WCF service(is this what you want?).

to-wcf-service-without-proxy.aspx

http://www.clariusconsulting.net/blogs/pga/archive/2006/08/07/639.aspx

For that case, I think you can try directly use the shared classes in class
library assembly directly(since there is no pregenerated proxy classes).

OK. I think it's starting to sink in. I'm going to end this thread since
the topic is now starting to converge with the WCF Advice thread I have
on going. If you would, please join me there.

Thanks,

Bill
