How to create a unique constraint on a varchar(max) field in visual studio, visually.

the problem is when i try it: manage indexes and keys > add > columns i can only chose the bigint columns, but not any of the varchar(max) ones.

do i maybe have to use check constraints? if yes, what to put in the expression?

thnx for the info
