I’m current using an evaluation version of Aspose.Pdf. My development environment is Visual Web Developer 2005 Express Beta 2.0. I’m programming in C#. The same code that works in the aspx.cs code behind file, doesn’t work when I move it to a separate C# file in the App_Code folder. In this file, it doesn’t recognize any Aspose.Pdf types and library functions. It has no problem with this in the code behind file. But once I moved the code to a separate C# file in the same project and wrapped the code inside a new namespace and class, it no longer works. ( Moving this code into a method inside this class allows me to execute the code when I invoke the method from the code behind file.) I don’t understand why all of a sudden the keywords are no longer being recognized. I’ve added a reference to Aspose.Pdf in the project and put in “using Aspose.Pdf”. Can someone help me please?
