Creating filtered collections
Sometimes, you may want to always return entities that match certain restrictions. For example, you may want to return orders that have been processed or are in a particular state. This recipe will explain how we can achieve that.
Getting ready
We will be using the NuGet Package Manager to install the Entity Framework Core 1 package, Microsoft.EntityFrameworkCore
. We will also be using a SQL Server database for storing the data, so we will also need Microsoft.EntityFrameworkCore.SqlServer
.
Finally, xunit
is the package we will be using for the unit tests and dotnet-text-xunit
adds tooling support for Visual Studio. Note that the UnitTests
project is a .NET Core App 1.0 (netcoreapp1.0), that Microsoft.EntityFrameworkCore.Design
is configured as a build dependency and Microsoft.EntityFrameworkCore.Tools
is set as a tool.
Open Using EF Core Solution from the included source code examples.
