Can we use "workaround to this" instead of "solution to this"?
Solution 1:
Workaround
A method for overcoming a problem or limitation in a program or system.

A means of solving a problem or dealing with a difficult situation.
-- Google Dictionary
A workaround is a way of avoiding the problem.
A solution fixes the problem.
They do both have the same outcome, but a workaround is like covering up a patch of damp with wall paper, rather than getting it waterproofed.
