I just installed Microsoft Visual C# 2010 Express (a compiler) on my machine and am working my way through sample programs provided by Microsoft. They run out of the Development environment OK but as soon as I attempt to run them directly they are quarantined by Sonar and deleted from my hard drive. They are very rudimentary samples that simply open a web page. The suspicious action is "Accessibility API usage". I can put them into the exceptions list but don't understand why this should be necessary and don't look forward to having to do this with anything I develop in the future.
