ef core Stored Procedure C# asp.net core
This post is on using stored procedure in EF Core. The support for stored procedure in EF Core is similar to the earlier versions of EF Code first. In this post I am using NorthWind database for demo purposes. I am using database first approach to generate model classes. First I have created three stored procedures. One will select all the rows in products table, another with a parameter and the third one is inserting the data to table. Here is the implementation.

This post is about building a custom dotnet cli tool, using this you can extend the dotnet cli for various operations like minifing images, scripts, css etc. The tools used by the .NET CLI are just console applications, so you can create a dotnet core console application and use it.

ASP.NET Core WCF Service C# .Net
This post is about consuming WCF Services in ASP.NET Core. With the availability of .Net Core RC2 and ASP.NET Core RC2 Microsoft introduced an update to the WCF Connected Service Preview for ASP.NET 5 Visual Studio extension tool for generating SOAP service references for clients built on top of WCF for .NET Core RC2. To consume a WCF Service, first you need to install the WCF Connected Service extension, which can be downloaded and installed using Extensions and Updates feature from Tools. Or you can download it from Visual Studio Gallery. Please make sure youre installing the required prerequisites, otherwise it may not install successfully. Once installation completed successfully, you can create a new ASP.NET Project and consume the service. This tool retrieves metadata from a WCF service in the current solution, locally or on a network, and generates a .NET Core 1.0.0 compatible source code file for a WCF client proxy that you can use to access the service.

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.

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 elephantsql.com. 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.
