FormHasMethod extension in D365FO

 FormHasMethod extension in D365FO

Every developer who has start working on D365FO face this issue that when we create method in form Extension

For verification of method exists or not in run time  we can use Global::formHasMethod but it does not work with form extensions

So i advise everyone to use below code its working...

using  System.Object;

using  Microsoft.Dynamics.Ax.Xpp;

using  System.Reflection;

    [ExtensionOf(classStr(Global))]

 final class Global_Extension

{

    static boolean formHasMethod(FormRun _fromRun, IdentifierName _methodName)

    {

        boolean flag= next formHasMethod(_fromRun, _methodName);

        if (flag==true)

            flag= Global::VerifyformExtensionHasMethod(_fromRun, _methodName);
