The InteropPermission class controls the ability to call unmanaged and managed code.
public ref class InteropPermission : Microsoft::Dynamics::Ax::Xpp::CodeAccessPermission[Microsoft.Dynamics.Ax.Xpp.KernelClass]
public class InteropPermission : Microsoft.Dynamics.Ax.Xpp.CodeAccessPermission[<Microsoft.Dynamics.Ax.Xpp.KernelClass>]

Remarks
The InteropPermission class is designed to check permissions for specific APIs. For a list of all APIs that are protected by permissions, see Secured APIs. Before the protected API is run, you must call the assert method on the same tier (usually the server tier) that the corresponding CodeAccessPermission::demand method is called on. Call a method on the server tier from one of the following methods:
- A server static method
- A class instance method that is set to run on the server by using the RunOn class property.
The following code example shows a new instance of the InteropPermission class. The assert method is called to declare that the code can then instantiate the DLL class that provides the ability to communicate with a Microsoft Windows dynamic-link library (DLL).
server static void main(Args args)
{
InteropPermission _perm;
DLL _dll;
_perm = new InteropPermission(InteropKind::DllInterop);
_perm.assert();
// Invoke the protected API.
_dll = new DLL('cfx2032.dll');
// Optionally, call revertAssert() to limit the scope of assert.
CodeAccessPermission::revertAssert();
}
