See code examples in this article: Let's imagine you have a solution with many projects including a web application with the name "MiniService", which contains appsettings.json and a library project with DbContext and Migrations with any name f.e. "MiniService.Data". You most likely want to use the exact connection string in the appsettings.json used by the web app. May be different cases when you will need to run migrations from the command line, for example, there is no 'Package Manager Console' in VS for Mac.

Advanced Entity Framework Core Tips In Practice: Context pooling, Lazy vs Eager loading, Single vs. Split Queries, Tracking vs. No-Tracking Queries

I am describing the practical aspects of working with Entity Framework Core. In this article I am touching Concurrency token and RowVersion, on save changes interceptor with a bunch of useful logic like tracking who and when did the change, versions, validations and domain events sending.

In this article, we will see how we can perform bulk operations (CRUD) using EF Core using .Net 5 template

EF Core’s owned types allow you to group fields, that you do not want to appear as a reference, in a separate type.

On the surface many-to-many in EF6 and EF Core look very similar. However, under the covers the design in EF Core 5.0 is much more flexible and powerfulIn this episode, Arthur Vickers returns to chat some more with Jeremy about some of the new features in Entity Framework Core 5. In particular, they’ll be diving deep into the building blocks of many-to-many. You’ll see how they can be configured to allow flexible mapping and access to the underlying join table.

EF Core 5.0 includes support for many-to-many relationships and TPT mapping, two sorely missed features from EF6. Join us for a whirlwind tour where we compare EF Core 5.0 features with those from classic EF6. In this episode, Jeremy chats with his teammate Arthur Vickers about some of the new and very useful features that are available in Entity Framework Core 5.

EF Core 5.0 Preview 8 features table-per-type (TPT) mapping, SQLite table rebuilds for migrations, and table-valued functions.

The major difference between First and FirstOrDefault is that First() will throw an exception if there is no result data for the supplied criteria whereas FirstOrDefault() returns a default value (null) if there is no result data.

Most of the people are implementing Multi-Tenancy using multiple databases, hence it's a good practice to distinguish tenant data on different databases. But in some cases, we have to implement multi-tenancy in the same database. So, I am going to write my logic on how I have implemented multi-tenancy on the same database. It will definitely help you.

Let us discuss some of the advantages and disadvantages of Code-First approach and Database-First approach of Entity Framework.

In EF (Entity Framework), there are mainly two ways to execute the stored procedure.

As per our old EF, we are using both the approaches that first create classes then you run it or compile it. It will create the database automatically. And the second approach first creates a database then create classes as per the database.

Recently, Microsoft has announced the release of Entity Framework Core 2.1 which is the latest production-ready release of the open-source and cross-platform data access technology.

DataAdapter is used to fetch the data from SQL

DataAdapter and datareader

1. ADO.Net is create bunch of data layer code, EF is not create. 2. EF is it auto generates code for middle layer,Data acess layer and mapping code so its reduce lots of development time. 3. ADO is faster than EF.

Entity framework is an Object/Relational Mapping (O/RM) framework. It is an enhancement to ADO.NET that gives developers an automated mechanism for accessing & storing the data in the database.

Microsoft has released the final version of Entity Framework Core 2.0.

if you want to have full control over schema then go with code first else DB first
