I have a problem with developing C# device application for WEC2013 on Apalis T30 (I’m using Visual Studio 2015). User controls added to project (and then rebuilded) are not visible in Toolbox.
I have found that this problem was already reported: link text but even if I move user controls to separate project and add dll manually I can’t see then in Toolbox. There is only information: “The following controls were successfully added to the toolbox but are not enabled in the active designer”. If I check “Show all” option I can see added controls but they can not be used in designer.
What am I doing wrong?
