Hello, I have created a new web site with Visual studio. When I have created the application in IIS, I have selected an application pool and afterwards I create my Web Site with Visual Studio and I copy the DLL WorkflowGen.My.dll in the folder bin. I add reference in the project. In the first step of my workflowgen I write in FORM_URL “C:\inetpub\wwwroot\wfgen\WfApps\WebFormsWorkflowGen” or “http://localhost/wfgen/WfApps/WebForms/WorkflowGenWebForm”. The message error when I start the Web Form application is : " *WorkflowGen.My can’t retrieve your language. Your session has probably expired." Have you an Idea to solve the problem?
