Is anyone using ClickOnce with VS2010?

I’m getting the following on publish, when the solution builds fine ...

Building WindowsFormsApplication1...
Er

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.
