LINQ StartsWith, EndsWith, and Contains are case sensitive and return false if two same strings are of different cases, e.g., "STRING" and "string".
string name = "STRING";
var employees = context.employees.Where(emp => emp.Name.Contains(name));
If in database employee name="string", no result will be returned. The most simple way is to convert both to lower case.
string name = "STRING";
var employees = context.employees.Where(emp => emp.Name.ToLower().Contains(name.ToLower()));
