Assemblies don't copy to bin directory

I have solution with 13 project. One project is WinForm (EArchive), other is class library. When I click on F5(Debug) or F6(Build Solution) the assemblies is building OK, but they don't copy to bin directory of EArchive. When I click right mouse button o开发者_Go百科n EArchive and select Build then works(but not all, for example don't copy resource file).

I have tried:

1. Delete all bin and obj folders.

2. Rebuild All.

3. Clean command from context menu.

Visual Studio 2010.

Thanks.

This sounds like the WinForm project is not set to be built in the solution's build configuration. I've encountered problems like this where a project will unexpectedly be unchecked in the Configuration Manager (under the Build menu). Check there.
