I'm new to my project, and to manage the database data, they utilised LINQ and Entity Framework. I'm not sure why the get() function is followed by a question mark (?) in the following query. Is it OK to use the (?) mark in the manner shown below? If so, do provide a detailed explanation.

                    .Where (x=>x.Name=="SomeConditions").Tolist();
