Hello,

it’s strange, when I create a new Wisej2 Web Application project, I get from the designer the above error. The Wisej2 toolbar is very short, too short (see image).

I updated Wisej on Friday to the current version and today I updated VS 2017 professional to the current version.

Any idea how get rid of that trouble?

 

Best regards

Johann

Hello Johann,

There is a missing Wisej DLL reference in the project.

Add manually a reference to : Program File\IceteaGroup\Wisej 2\bin\Wisej.Framework.Design.dll

Then exit the program and reload.

This should help.

 

Regards.
