DLL Library containing ASPX Pages

[Guest]

Hello,

I have some Web Applications that need to have the same export functionnality.

In Windows Application, I have created a DLL Library that containt WinForms
to serve this export functionnality.

I cannot find any way to do this in Web developpement.
The major problem is that the application context must be the same. So
create two separated application is not possible.

Thanks
