I am using VS 2015 with InstallShield 2015 limited edition. In debug mode everything runs fine. But when I try to build the project in Release/SingleImageMode I get the -6225 error with this message:

-6225: Resolving Visual Studio .NET project output "UI\Controls\VET.UI.Controls.MapView\VET.UI.Controls.MapView.csproj\|Built"

Can someone please help me out with this problem? I am new to InstallShield, so I wonder if I'm missing something.
