html - LESS nested rule with inherit parameters -

i know if less admit kind of operation variables:

.class(@a, @b) {     color: @a;     background: @b;      &:hover     {          color: @b;          background: @a;     } } 

because when doing it, web matrix 3 throws me following error inside :hover section: "undeclared variable"

if not admitted, can possible solution?

thank in advance. cheers.

that's bug in webmatrix; less valid.

you can make shorter this:

.class(@a, @b) {     &, &:hover     {          color: @b;          background: @a;     } }
