It's up to each individual who they decide to trust. A lot of damage can be done with an application without it being detected as virus. Think IO.File.Delete for starters. I partially agree the main interest in your projects for users of this forum would be source code, or perhaps screenshots if you want to discuss layout/presentation. If you want "beta testers" for feedback to usability then they would have to decide to trust your app, you also have to provide the compiled assembly from your own site, we usually remove compiled assemblies from attachments here for same reasons. It also saves a lot of storage space, and they are not needed since they are compiled from source code during debugging anyway. Remember this is a community for discussing VB.Net development.
