When we complete a project, we generally need to use the "Installation and Deployment Project" of VS.NET to create a setup. Maybe you sometimes encounter such an error:
Error: The project output group cannot be generated "content file from WebApplication1 (Event)".
Sometimes I can't find a mistake, where is it, it may be produced by the following reasons:
Try in the Solution Explorer, refresh the target item to see if there are some files in the project (in an exclamation mark identifier, as shown below), if there is, put all these files or "from the project Exclude, then regenerate the installation package.
(Note: This problem is what I have encountered in development. At that time, it was caused by this reason, there may be other reasons, if you find other reasons, this error will be generated, welcome to leave here, Thank you!)
