 Common objects between windows app and asp.net app Hi, I've written an application that shares a common class module between a
windows project, and an asp.net project. I want to a write a configuration
class that reads configuration settings from an xml file and contains a
complex configuration structure. The configuration is to be read from an
xml file and used inside the common class module. The problem is that I
would like to read the configuration file only the first time, and then
store the information in some sort of in-memory global application store.
That way, the next time the class is used, it can just grab the information
from the application store.
I know that if I was writing strictly for a web app, I could use
system.web.httpcontext.current.application. Is there some sort of common
application object I can store this information in, and share with both
apps?
Alternatively, it is less important that I use an application-style object
in the windows app. I suppose if there was some way I could tell which
application I was in, I could use code like this:
if (IamInaWindowsApplication) then
....read configuration directly from XML File
elseIf (IamInaWebApp) then
....read configuration from application object
end if
Thanks,

Common objects between windows app and asp.net app You may want to consider using the standard web.config/app.config files and let Microsoft deal with your problem so you don't have to. It is easy enough to create a custom section in the config file, and the
.NET framework will automatically take care of caching the data in both the
winforms and webforms environments.

Common objects between windows app and asp.net app I am currently looking at instantiating this configuration class as a singleton pattern. For an example, see http://www.dotnetextreme.com/code/Singleton.asp. Is this a valid approach to my problem? How does declaring a shared object in asp.net work? Is the object shared accross all sessions, or will I run into conflicts using this approach?

Common objects between windows app and asp.net app Thanks, We started out using the standard web.config/app.config file solution, but
we are targeting a highly configurable application that we can deploy
hundreds of sites with a single code base. Using the web.config file was a
workable solution, but we are finding it is becoming harder to maintain. We
could use the same style of approach with our new config file, but we do not
want the system to have to reload the entire configuration into our
configuration class structure on each page load.
The reason we decided to go to a custom configuration scheme is that we want
to provide the ability to add a arbitrary level of custom attributes for
each object in our system.

Common objects between windows app and asp.net app After testing it out, it seems the singleton object is happily passed between sessions in ASP.NET. Is this any different than using the application object?
