Question

In visual studio, I create a reference to the Aspose assembly and use the Document class in my code. It looks fine at design-time, but when I go to compile I get the error ‘Type Aspose.Words.Document’ is not defined.’ If I do anything that changes the project file, like add or drop a reference or add a new file, the errors go away… until I try to compile again.

Has anyone else seen this weird behavior and know how to fix it? Here’s my code if it matters, but it doesn’t get much simpler:

Module Module1

    Sub Main()

        Dim license As New Aspose.Words.License()
        license.SetLicense("Aspose.Words.lic")

        Dim files = My.Resources.files.Split()

        For Each file In files
            If file <> "" Then
                Dim changed As Boolean = False
                Console.Write("Processing " & file & "...")

                Dim doc = New Aspose.Words.Document(file)

                If doc.Range.FormFields("CurrDate") IsNot Nothing Then
                    doc.Range.FormFields("CurrDate").TextInputType = Aspose.Words.Fields.TextFormFieldType.RegularText
                    doc.Range.FormFields("CurrDate").TextInputFormat = ""
                    doc.Save(file)
                    Console.WriteLine("done.")
                Else
                    Console.WriteLine("not applicable.")
                End If

            End If

        Next
        Console.Read()
    End Sub

End Module

Answer 1

I found that it must be because the dll is targeting a different framework than what was specified in the project. I created a new console app that targeted 3.5 instead of 4.0 and it started working.
