The most important design change has to do with how we handle LINQ expressions that cannot be converted to parameters or translated to SQL. ![]() The new LINQ provider is the foundation over which we’ll be able to offer new query capabilities and performance improvements in future releases, without breaking existing applications and data providers. We rearchitected our LINQ provider to enable translating more query patterns into SQL, generating efficient queries in more cases, and preventing inefficient queries from going undetected. Here are some of the most important ones: LINQ overhaul Including major features, minor enhancements, and bug fixes, EF Core 3.0 contains more than 600 product improvements.

To install the final version of our 3.0.0 tool as a global tool, use the following command: dotnet tool install -global dotnet-ef -version 3.0.0 Before you can execute EF Core migration or scaffolding commands, you’ll have to install this package as either a global or local tool. When upgrading applications that target older versions of ASP.NET Core to 3.0, you also have to add the EF Core packages as an explicit dependency.Īlso starting in 3.0, the dotnet ef command-line tool is no longer included in the. For example, to add the SQL Server provider to your project, you can use the following command using the dotnet tool: dotnet add package -version 3.0.0 How to get EF Core 3.0ĮF Core 3.0 is distributed exclusively as a set of NuGet packages. NET Core 3.0 and ASP.NET Core 3.0 are also available now. We are extremely excited to announce the general availability of EF Core 3.0and EF 6.3 on. ![]()
