ASP.NET Core Logging Log4Net
This post is about using Log4Net with ASP.NET Core for implementing logging. The Apache log4net library is a tool to help the programmer output log statements to a variety of output targets. log4net is a port of the excellent Apache log4j™ framework to the Microsoft® .NET runtime. We have kept the framework similar in spirit to the original log4j while taking advantage of new features in the .NET runtime.

Repository Unit Of Work Design Patterns ASP.NET Core
This post is about implementing the Repository and Unit of Work Patterns in ASP.NET Core. The repository and unit of work patterns are intended to create an abstraction layer between the data access layer and the business logic layer of an application. Implementing these patterns can help insulate your application from changes in the data store and can facilitate automated unit testing or test-driven development (TDD). Long back I wrote a post on implementing a generic repository in ASP.NET 5 (Yes in ASP.NET 5 days, which can be used in ASP.NET Core as well.). So I am not explaining more on Repository pattern. The UnitOfWork pattern is a design for grouping a set of tasks into a single group of transactional work. The UnitOfWork pattern is the solution to sharing the Entity Framework data context across multiple managers and repositories.

aspnet core HangFire
This post is about integrating HangFire With ASP.NET Core. HangFire is an incredibly easy way to perform fire-and-forget, delayed and recurring jobs inside ASP.NET applications. CPU and I/O intensive, long-running and short-running jobs are supported. No Windows Service / Task Scheduler required. Backed by Redis, SQL Server, SQL Azure and MSMQ. Hangfire provides a unified programming model to handle background tasks in a reliable way and run them on shared hosting, dedicated hosting or in cloud. The product I am working has a feature of adding watermark to the images uploaded by users. Right now we are using a console app, which will monitor a directory in specified intervals and apply watermark to the newly uploaded images. But using HangFire we can schedule / execute the watermark opertation as a background task, instead of polling a directory for new images.

dotnet core MEF aspnet core
This post is about using MEF (Managed Extensibility Framework) in .NET Core. The Managed Extensibility Framework or MEF is a library for creating lightweight, extensible applications. It allows application developers to discover and use extensions with no configuration required. It also lets extension developers easily encapsulate code and avoid fragile hard dependencies. MEF not only allows extensions to be reused within applications, but across applications as well.
