System.MethodAccessException: Attempt by security transparent method ‘xc0a8130c468d13ee.x5d2e33120f57f9ce+xd3534b62823d287a.x900b3a0ecc9d8e31()’ to access security critical method ‘System.Runtime.InteropServices.Marshal.Copy(IntPtr, Byte[], Int32, Int32)’ failed.
Assembly ‘Aspose.Pdf, Version=4.8.0.0, Culture=neutral, PublicKeyToken=716fcc553a201e56’ is marked with the AllowPartiallyTrustedCallersAttribute, and uses the level 2 security transparency model. Level 2 transparency causes all methods in AllowPartiallyTrustedCallers assemblies to become security transparent by default, which may be the cause of this exception.

Hi Klaus,
Thanks for contacting support and sorry for the delayed response.
Can you please share some details regarding your requirement i.e. the feature you are trying to accomplish with Aspose.Pdf for .NET. Also can you please share some code snippet/sample project which can help us in replicating this issue at our end as I am afraid its quite difficult to figure out the problem from StackTrace (all I can understand is that you are trying to convert images to PDF format). We are sorry for this inconvenience.
BTW, I have observed that you are using quite older release of Aspose.Pdf for .NET and the latest release of Aspose.Pdf for .NET is 9.3.0.
