July 16, 2016 by Anuraj

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.

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.
