Solution 1

Looks like you are using Contains in your LINQ where clause.

LINQ to SQL will translate a Contains() to a SQL LIKE statement which is not case sensitive in general.

Try:
OPTION 1:

s = From row In context.Table Where String.Compare(row.Name, "test", StringComparison.CurrentCulture) = 0

OR

OPTION 2:
If you want to use the Contains clause then, best way would be to create your own comparer. Look here:
Enumerable.Contains[^]

I told what/how to do in case you want to use Contains.

Solution 3

Change the Collation in the database or write something like this:
tblUsers
.Where (u => u.userName.Contains("Test")).AsEnumerable()
.Where (u => u.userName.IndexOf("Test", StringComparison.CurrentCulture) != -1)
