Let's get ready to create the ASP.NET Core application to use the .NET Standard library we have built in the previous recipe when we created the .NET Standard library. If you haven't followed that recipe, make sure you have completed it. We are going to use that solution and add the ASP.NET Core application to it. Also, make sure you have downloaded and installed the latest version of .NET Core Framework, which is available at http://www.dot.net/core.
Open Visual Studio 2017 and open the solution we saved from the previous recipe. Click Build | Build Solution, or press Ctrl + Shift + B, and the solution should build successfully. Everything's ready for testing our class library.
