In production environment when any bug gets reported at that time as developer wants to get the exception details of bug to resolve the issue on high priority. In some case there might be situation where exception is not logged in table but developer wants to check the bug immediately. for that purpose we need to write the exception details including stack trace of bug in file. To implement this easily i am going to demonstrate the implementation of custom logging in file as below. First we need to construct the exception and logger method in custom logger class as shown below. public class CustomLogger { public static List<string> ConstructExceptionDetails(Exception ex,string FunctionName) { return new List<string>() { $"{DateTime.Now} - {FunctionName}", $"Exception: {ex.Message}", $"StackTrace: {ex.StackTrace}", $"InnerException: {ex.InnerEx

In Linq or entity framework, we use IEnumerable and IQueryable for data manipulation or query data. IEnumerable is inherited by IQueryable , Hence IQueryable has all the features of IEnumerable and except this, it has its own features and benefits. Both have its own importance to query data and data manipulation in different situations in the application. we can go through with both the features and take the advantage of both the features to boost the LINQ Query performance. As per the need of application at some stage  IEnumerable is useful and some stage in the application  IQueryable is useful. Lets discuss about its use and features now. IEnumerable Features: IEnumerable exists in System.Collections Namespace. IEnumerable can move forward only over a collection, it can’t move backward and between the items. IEnumerable is best to query data from in-memory collections like List, Array etc. While query data from database, IEnumerable execute select query on server side,
