Ok, i figured out whats to do:
- Install the Poco precompiled files or compile them by your self
- Create a project, use msbuild
- In the projects VisualGDB settings, under MSBuild settings add the needed Informations
- Include directories (e.g. /usr/include/Poco)
- Library names (e.g. PocoNet)
This compiles and IntelliSense works fine.
