I am trying running into a problem in my instance where I'm encountering a problem when I publish and compile where I receive a message saying that "One or more errors occurred. Sequence contains more than one matching element"
I am unclear as to what this message could be referring to. There error is unclear and I'm unsure as to how to proceed without more information. Has anybody encountered this problem before?
If it's a compilation error, maybe there is more details in the Compilation errors? In the lookups section, add the "Compilation errors" object to view the contents.
