Development Environments

You can use Aspose.HTML for .NET to develop applications in any development environment that targets the .NET platform, but the following environments are explicitly supported:

  • Microsoft Visual Studio 2005
  • Microsoft Visual Studio 2008
  • Microsoft Visual Studio 2010
  • Microsoft Visual Studio 2011
  • Microsoft Visual Studio 2012
  • Microsoft Visual Studio 2013
  • Microsoft Visual Studio 2015
  • Microsoft Visual Studio 2017
  • Microsoft Visual Studio 2019

Trust Level

Generally, all Aspose .NET components require Full Trust permissions set. The reason is, Aspose .NET components need to access registry settings, system files, other than virtual directory, for certain operations, like reading fonts etc. Moreover, Aspose .NET components (including Aspose.HTML for .NET) are based on core .NET system classes, that also require Full Trust permissions set in many cases.

Internet Service Providers, hosting multiple applications from different companies, mostly enforce a Medium Trust security level. In case of .NET 2.0 such a security level may set the following constraints, which could affect the ability of Aspose.HTML for .NET to perform properly:

  • RegistryPermission is not available. This means, you can’t access the registry.
  • WebPermission is restricted. This means, your application can only communicate with an address or range of addresses, that you define in the element.
  • FileIOPermission is restricted. This means, you can only access files in your applications virtual directory hierarchy.

Due to the reasons, specified above, it is recommended, that Aspose.HTML for .NET is run on servers granting Full Trust permissions.
