Hi!
It seems Razor Engine is adding somente "empty using" into my e-mail template. This happens time to time and restarting IIS website solves it.

however, i need to know why it happens and how to address this issue.

Can anyone help or give me a clue?

this is erro generated

this is the source code generated with the empty using
