Little late for this comment, but I found this question because I was experiencing the same thing. Offering this here because the suggested work-arounds did not work for me.

My project builds and runs without error. I tried a build-clean, manually deleting the projects bin/ and obj/ folders, even using the Publish Wizard/Build-Menu->Publish. All would fail with the described "Cannot publish because a project failed to build."

Here's what made it work for me: I'm publishing to a UNC path, but the Installation Folder URL (on the project-setting's Publish tab,) was set to a URL that's exposed by IIS running on the server that also exposes the UNC path. I tried just setting the Installation Folder URL to the UNC path, and the ClickOnce build finally built and published. I don't get the web page, but we can live with that for now.

This is a bug in VS2010. I was able to publish 24 times without any problems. The 25th time refused to work, unless I did a right click on the project and published. I was getting the exact same error with no warnings. I have all the latest updates and did not change any settings in VS2010.

I asked the ClickOnce product lead about this, and he said it is a problem with DevExpress. They offer a solution here: http://www.devexpress.com/Support/Center/p/B156192.aspx

I was getting this error because my disk was near full. I moved 10GB to another drive, restarted Visual Studio.

The error still occurred if I click "Publish Now", but using Build >> Publish [ProjectName] worked normally.

I haave been using ClicKOnce successfully with VS2010 for several week.s

This is not a ClickOnce problem, it's a build problem. What is the rest of the error message, i.e. why can't the project build?
