Nevron Open Vision provides support for Visual Studio 2015.
We were able to reproduce the warning message in a VB.NET project – it appears when you run the Code Analysis. However, your project (and the NOV Example Solution) should be compiling without problems. The Code Analysis may be configured to run by default within your VS. You can check the configuration for the VS Code Analysis.
We got a suggestion from the built-in code analyzer to simplify the type name. Since the class name from the second message is VisualBasicSimplifyTypeNamesDiagnosticAnalyzer, we suppose that it occurs because the code analyzer does not work properly when attempting to analyze the type name or suggest an alternative name. We suggest that you contact the Roslyn community regarding this issue.
