I have a VB6 project that is written to interact with Fortran and get the data back to the user. We opened up Fortran and through the wizard created the module containing the Automation interface of the objects. This process created a whole bunch of code in a .F90 file. This works fine and we get the desired results that we are looking for. However when i upgraded the code to VB.Net and tried to replicate the steps through Wizard we don't get the similar code that was generated for VB6. Infact a .F90 file is created with just about 6 lines of code and at the end of the code we see a line that says " ! No interfaces of the type requested were found". On the first screen of the wizard i check the box "Generate code that uses automation interface" and then i can choose any options on the second screen and get the same results all the time. Am i not following some steps or missing some steps? I am using Windows 7, VS 2008 and Studio XE 2013. Please let me know what i need to do as i have spent quite a bit of time trying to make this work.
