An exception with the following stack trace occurs when using features that perform HTML sanitization and running the site in 32-bit mode:

There is a native dll included, osafehtml.dll, that is pinvoked for HTML sanitization, that is compiled in 64-bit mode and causes this exception when pinvoked in 32-bit processes.

The installation instructions do indirectly mention using the 64-bit configuration when publishing the site to an Azure web app. I've verified this error occurs with on-premise IIS hosting and in Azure.

Actions:

  1. List 64-bit as a requirement in installation instructions IIS image Azure Web App image

  2. Consider replacing HTML sanitization with a managed library, as already listed in the Update SafeHtml to use only managed code project.

64-bit requirements handled by commit https://github.com/Adoxio/xRM-Portals-Community-Edition/commit/259cfb2a9211a176ff8a185443946bf58ecdb016.

HTML sanitization library changes will be handled separately if determined to be appropriate.
