Unable to build project output group Content Files from

Question

currently I'm trying to create an WebSetup Project for one of our ASP.net4/Silverlight-Web Applications using Visual Studio 2010.

I created the setup Project according to this tutorial, but when I'm trying to build the Setup Project (I did a build of the whole solution before), I get the following error:

Unable to build project output group 'Content Files from MyWebProject (Active)'  

According to this and almost any other site I found, this error refers to items that are included in the web-project but missing on disk.

I checked all my projects twice, there is no missing file. Are there any other solutions to this problem?

Other things I tried:

• This post: I do have .xml Files accompanying our .dlls. I also removed the xml File from my project, but it didn't help either

• This post: Setting the startup project to my web application changed nothing.

Both of the above Posts are from this thread on forums.asp.net.

I had this problem also. (Visual Studio 2010 Pro, .Net 4.0) I found the missing file using "Publish..." option. Right click on the web app. Up near the top of the menu (5th from the top for me) is "Publish...". Click that. I did "Publish method: File System". Publish fails for the same reason that building the setup fails. The difference is that when Publish fails, it gives an error message.
