Hi Martin,
As noted in
MSDN you get this warning because the CurrencyCultureEditor class is in the Syncfusion.Windows.Forms.Tools.Design namespace, which is used in the both these assemblies:
Syncfusion.Tools.Windows.dll and
Syncfusion.Shared.Base.dll
Can you try building your application after turning off Treat Warnings As Errors.
Regards,
Arun
