Aspose.Pdf and Medium trust

PhilMIntertec · May 23, 2017, 2:46am

Hi Nayyer

Thank you for your reply. Despite Medium Trust being obsolete, it appears our hosting company still maintains this as a requirement. What are our options? Older DLL? Custom DLL? Other?

Note we run Aspose Cells on the same hosted environment with no problems.

I'm open to all suggestions and would really love to be able to use your aspose.pdf product in the same way we currently use aspose.cells.

Many thanks

Phil

Hi Phil,

Thanks for your patience.

I have further discussed the scenario with product team and in current circumstances, you may consider following either approach

Use old version of API (version 9.2) which was tested and worked well under medium trust.
Please try using latest release and in case you encounter any issues, please share the details and we will investigate and fix them.

Hi

I've tried using the older DLL 9.2, but still get this error:

Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request failed.

Here is the assembly info for the older DLL:

Hi Phil,

Thanks for contacting support.

Please take your time and note that we already have tested Aspose.Pdf for .NET 9.2 in trusted environment and it worked without any problem. In case the problem still occurs, please share some details on how you have used the API and if possible, please share a sample project, so that we can further investigate the scenario in our environment. We are sorry for this inconvenience.

Thanks again Nayyer

I am now using v9.2 and I'm getting the following error.

Cannot find license 'Aspose.Pdf.lic'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.IO.FileNotFoundException: Cannot find license 'Aspose.Pdf.lic'.

Is there anything unusual about the way v9.2 handles license files?

Kind regards

Phil

Hi Phil,

Thanks for sharing the details.

There has been no change related to license initialization in recent release versions. However concerning to above error message, ensure that license file is preset and has same name as specified in code snippet and also ensure that your application has access to location containing license file.

In case the issue still occurs, can you please share if the same issue occurred when tested the latest release versions. We are sorry for this inconvenience.
