Use Aspose.PDF in ASP.NET Application

I'm currently using an evaluation copy of Aspose.Pdf version

For the second day in a row I've experienced the following:
I can develop, debug and run my test ASP.NET app just fine for a few hours, then I receive this error:

Parser Error Message: Access is denied: 'Aspose.Pdf'.

Source Error:

I have to re-boot my machine to clear the error. What could possibly be the problem?

I’m also getting this error. I don’t know why this happens, but it’s not only the aspose products which gives these errors.

The solution is to shut down the “indexing service” (Administative tools - services).

Best regards,


This could really become a big problem if this starts happening on our production server. Does anyone know of a reliable way to resolve this problem?

You could try to set the Indexing Service to start manually. I’ve never had any problems with this on the production server, only when I’m developing. Another thing is that I’m the only one of the people I’m developing with who has this problem, so I don’t know if it might be that I have some other application installed which causes the problem.

This is the only solution I’ve got, and if anyone knows a better way to solve it, I would also be glad to know how.
