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/CMSManagedT
This bug still exists in ASP.NET 4.0.
The error I got was:
/DirA/PageA.aspx(3): error ASPPARSE: Circular file references are not allowed.
/DirA/PageA.aspx(71): error ASPPARSE: Unknown server tag 'Controls:ControlA'.
ControlA was the same control as referenced on PageA.aspx(3). I found that I had to move ControlA into the same directory as PageA in order to make this error stop.
