.NET Framework Assemblies Callable by Partially Trusted Code

To enable key scenarios several .NET Framework assemblies can be called by partially trusted code. Some code within these assemblies might be subject to security restrictions, including requiring callers to be fully trusted in some cases. All other assemblies that are part of the .NET Framework are intended for use only by fully trusted code.

The following .NET Framework assemblies have the AllowPartiallyTrustedCallersAttribute (APTCA) or the SecurityTransparentAttribute attribute applied:

  • Accessibility.dll (APTCA)

  • Microsoft.JScript.dll (APTCA)

  • Microsoft.VisualBasic.dll (APTCA)

  • Mscorlib.dll (APTCA)

  • System.dll (APTCA)

  • System.Configuration.dll (APTCA)

  • System.Data.dll (APTCA)

  • System.Data.Linq.dll (security-transparent attribute)

  • System.Deployment.dll (APTCA)

  • System.DirectoryServices.dll (APTCA)

  • System.DirectoryServices.Protocols.dll (APTCA)

  • System.Drawing.dll (APTCA)

  • System.Security.dll (APTCA)

  • System.Transactions.dll (APTCA)

  • System.Web.dll (APTCA)

  • System.Web.Mobile.dll (APTCA)

  • System.Web.RegularExpressions.dll (security-transparent attribute)

  • System.Web.Services.dll (APTCA)

  • System.Windows.Forms.dll (APTCA)

  • System.XML.dll (APTCA)
