INGEAR.NET throws a license exception in Visual Studio even though a valid Developers license is present.

Cause - There is a runtime deployment license file (*rt.lic) in the ouput folder of your project.  The runtime deployment license file does not support operation in Visual Studio IDE.

Solution - Delete the (*rt.lic) fle from the output folder.  If the runtime license file is included in your project set the property Copy to Output = Copy Never in Visual Studio Solution Explorer.  Clean and rebuild your project.   When you're ready to create a deployment and distribution package, set the file property Copy to Output = Copy Always then publish your project.
