Hello,

I tryed to update from 2022.0.30 to 2022.1.67 in a WPF project and i'm now getting this error :

MC3074 The tag 'WebControl' does not exist in XML namespace 'http://schemas.essentialobjects.com/wpf/'

My code didn't change, and it is like the documentation :

Code: HTML/ASPX 
xmlns:eo="http://schemas.essentialobjects.com/wpf/"

<eo:WebControl>
</eo:WebControl>



Regards,

Hi,

Please change your project to target .NET Framework 4.6 and above. Build 22.1.67 no longer supports older versions of .NET Framework.

Thanks!
