ASP.NET Core Nuget EF Entity Framework

This post is about reverse engineering model classes from existing database using Entity Framework Core. This is useful in Database First scenarios than the Code First scenario. In order to scaffold a DbContext from an existing database, you first have to set up project.json file. You need to add reference of Entity Framework tools in the project.json file tools section. For this post I am generating DbContext and model classes from Sqlite Database. So I am using EF Sqlite references as well.

ASP.NET Core Nuget

While developing ASP.NET Core you might face some situations where you have the source code with you, but the nuget package is not available. One example is ImageProcessorCore where source code is available, but nuget package is not available, if you want to use this library in your project, you first need to create a package out of it and host it locally.

ASP.NET Core PostgreSQL EF Migration

This post is about using PostgreSQL with ASP.NET Core. PostgreSQL is an object-relational database management system (ORDBMS) with an emphasis on extensibility and standards-compliance. Recently in ASP.NET Forums, someone asking about using postgresql with ASP.NET Core. Since I don’t have an installed version available, I thought I will use postgresql as a service version from They are offering a free tier postgresql database. You can register yourself and can create databases. In this post I am using EF Migrations for creating databases. So I am using a ASP.NET Core Web API project, I have created a API project with ASP.NET YO Generator. To connect to postgresql server, you require “Npgsql.EntityFrameworkCore.PostgreSQL” nuget package, and for EF migrations you require “Microsoft.EntityFrameworkCore.Tools” package. Here is the project.json file.

Bundling and Minification in ASP.NET Core

ASP.NET Core Bundling Minification

This post is about Bundling and Minification in ASP.NET Core. Bundling and minification are two techniques you can use in ASP.NET to improve page load performance for your web application. Bundling combines multiple files into a single file. Minification performs a variety of different code optimizations to scripts and CSS, which results in smaller payloads. In ASP.NET Core RTM release Microsoft introduced “BundlerMinifier.Core” tool which will help you to bundle and minimize Javascript and style sheet files. Unlike previous versions MVC, the bundling and minification is happening on development time not in runtime. To use “BundlerMinifier.Core” first you need to add reference of BundlerMinifier.Core in the project.json tools section.

ASP.NET Core with Nginx as reverse proxy

Posted by Anuraj on Tuesday, June 28, 2016

ASP.NET Core Nginx Reverse Proxy Load balancing

This post is about running your ASP.NET Core application with Nginx as reverse proxy on Windows. Nginx is a web server. It can act as a reverse proxy server for HTTP, HTTPS, SMTP, POP3, and IMAP protocols, as well as a load balancer and an HTTP cache. Nginx runs on Unix, Linux, BSD variants, OS X, Solaris, AIX, HP-UX, and Windows. Released under the terms of a BSD-like license, Nginx is free and open source software. Few months back on K-MUG Techday, on a NodeJS session, I asked the question about using NodeJS in enterprise project, then I got introduced to Nginx and reverse proxy concepts in NodeJS. Similar to Node, ASP.NET Core is also supports the Kestrel hosting than IIS, it can be also used along with Nginx and can be hosted in Linux as well..

Posted by Anuraj on Tuesday, June 28, 2016

C# ASP.NET ASP.NET Core Docker Container

This post is about running your ASP.NET Core application on Docker for Windows. Docker containers wrap a piece of software in a complete filesystem that contains everything needed to run: code, runtime, system tools, system libraries – anything that can be installed on a server. Recently Docker introduced Docker for Windows and ASP.NET Team came up with Docker support for ASP.NET Core as well. To deploy ASP.NET Core application, first you need to download the docker for Windows. You can get it from here.
