VB.net with SQL

Hi there, this question may seem unreasonable or
this forum maybe a wrong but i donno anywhere
else to post this but here since it's Vb.net related.

Before i migrated to VB.net (with SQL),i have been using
VB6 with Access database where after a project i just
have to compile n deploy it together with a copy of
the access database

I have now develop a VB.net project (with SQL backend)
My question then is...
do i have to install SQL database on the client's PC
before my project can run successfully?
