I have an InfoPath form with a code-behind C# solution. Every time I open the form (design mode) and open the Visual Studio Tools for Applications (VSTA), the reference to System.Windows.Forms
is missing from the project. When I add it manually everything works. I also tried setting the property Copy Local
to true or copy the dll-file in a folder and set that property to true, but this doesn't work either. Does anyone have an idea how I can solve this?
