Hi,

I am having a problem in building my solution in VS2008. Normally, it compiles fine in the environment. Sometimes, it fails with:

/xxx_WEB/secure/CMSManagedTargetPage.aspx(1): error ASPPARSE: Circular
file references are not allowed.

I rebuild and it works fine.

Now, however, I am in the middle of setting up a CruiseControl.NET system and am testing my checked out code with MSBuild before I integrate the build into CC. Now, everytime I MSBuild, I get:

"Q:\cc\xxx\checked out from svn\xxx.sln" (default target) (1) ->
(xxx_WEB target) ->
  /xxx_WEB/secure/CMSManagedTargetPage.aspx(1): error ASPPARSE: Circular
file references are not allowed.

Problem is, I can't see where this reference is.

• I have searched for the reference across the entire solution and canf ind no references to the page itself (CMSManagedTargetPage) anywhere other than in the page or its codebehind, or within a string, eg:

  C:\dev2008\xxx\IWW.xxx.ASPNET\AspxHttpHandler.cs(82): inputFile = context.Server.MapPath("~/secure/CMSManagedTargetPage.aspx"); C:\dev2008\xxx\IWW.xxx.ASPNET\AspxHttpHandler.cs(83): virtualPath = "~/secure/CMSManagedTargetPage.aspx";

My assembly references are also fine (as far as I know). My Web Application is at the "top" of the dependencies, and nothing references it and therefore the faulting page so cannot cause a circular reference. Of course, the page itself may reference something such as a UserControl within the same assembly/web site, but as mentioned earlier, a search on CMSManagedTargetPage yielded no results so this is not happening.

Changing the batch attribute in web.config had no effect on MSBuild.

I find it very odd that it "sometimes" fails in VS and always fails in MSBuild. Am I missing some subtlety?
