AllowPartiallyTrustedCallersAttribute.PartialTrustVisibilityLevel Property


Gets or sets the default partial trust visibility for code that is marked with the AllowPartiallyTrustedCallersAttribute (APTCA) attribute.

 property System::Security::PartialTrustVisibilityLevel PartialTrustVisibilityLevel { System::Security::PartialTrustVisibilityLevel get(); void set(System::Security::PartialTrustVisibilityLevel value); };
public System.Security.PartialTrustVisibilityLevel PartialTrustVisibilityLevel { get; set; }
member this.PartialTrustVisibilityLevel : System.Security.PartialTrustVisibilityLevel with get, set
Public Property PartialTrustVisibilityLevel As PartialTrustVisibilityLevel

Property Value

One of the enumeration values. The default is VisibleToAllHosts.


The following examples demonstrate how to use this property.

  • Default, unconditional APTCA:

    [assembly: AllowPartiallyTrustedCallers]  

    Defaults to VisibleToAllHosts.

  • Explicit, unconditional APTCA:

    [assembly: AllowPartiallyTrustedCallers(PartialTrustVisibilityLevel=VisibleToAllHosts)]  

    The assembly can always be called by partial-trust code.

  • Explicit, conditional APTCA:

    [assembly: AllowPartiallyTrustedCallers(PartialTrustVisibilityLevel=NotVisibleByDefault)]  

    The assembly has been audited for partial trust, but it is not visible to partial-trust code by default. To make the assembly visible to partial-trust code, add it to the AppDomainSetup.PartialTrustVisibleAssemblies property.
