No, they cannot. In order to create a ClientAce project that can be signed, a project must have the ability to be compiled as an executable. ASP.Net applications cannot be compiled as executables. At this time, only C# or VB.Net Windows Forms, WPF Forms, Consoles, or Service Applications have this ability. To work around this limitation, users can create an ASP.Net project and a console or service application using ClientAce. In this application, ClientAce code can be used to read OPC data and then write that data to a data source that can be used by ASP.Net. The data handling side can be ADO or LINQ.
