Azure Cosmos DB and EF Core - Entity Framework Community Standup

EF Core may be an object relational mapper, but it also can ditch the relational and connect directly to the Azure Cosmos DB NoSQL engine. In this standup, the team will discuss the rationale behind a Cosmos DB provider, show code examples, discuss the major differences between SQL and NoSQL data and share the roadmap for future enhancements to the Azure Cosmos DB provider.

Introducing EF Core Compiled Models - Entity Framework Community Standup

EF Core creates an internal model for entity types and their database mappings. This model is typically built once when the application starts. Starting with EF Core 6.0, it is now possible to instead build this model at compile time. This can reduce startup time by up to 67% for large models. Join us for this Community Standup, where the team will introduce compiled models and demo their use.

➤ How to create Scaffolding and How to create Controller and Views with Scaffolding in Visual Studio.
➤ Explanation of Code generated and How entity Framework Core works.
➤ How to do validation in Forms and how to use ASP.NET Core Tag helpers for that.

Due to limitation of time and big video length I was not able to the explain few topics in that video. So I thought it will be a good idea to create a video which explains how it works

So following topics are included in this video.
➤ What is Controller
➤ What is Action Methods
➤ Limitation of Action methods
➤ How Add, Edit, Delete and Get data from the SQL Server database with the help of Entity Framework Core 5.0
➤ How action methods are map with URLs via routing.

Build a Basic GraphQL Server With ASP.NET Core and Entity Framework in 10 Minutes

We will create an API that presents a movie and its reviews. In GraphQL, queries are used to read data, and mutations are used to create, update and delete data.

Since I wrote my first GraphQL post in 2019, much has changed with GraphQL in the .NET space. The ongoing changes have also affected most of the documentation available online. This article will walk you through the steps to create a basic GraphQL API on ASP.NET Core using GraphQL for .NET, Entity Framework Core, Autofac, and the Repository design pattern. I chose the tech stack for the sample application based on the popularity of the frameworks and patterns. You can substitute the frameworks or libraries with equivalent components in your implementation.

If you are not familiar with the concepts of GraphQL, please take some time to read the learn series of articles on the GraphQL website. Let’s now fire up our preferred editor or IDE to get started.

Application: Movie Reviews

We will create an API that presents a movie and its reviews. In GraphQL, queries are used to read data, and mutations are used to create, update and delete data. To explore the CRUD operations on data, we will create two GraphQL operations as follows:

  1. Query to fetch a movie by its identifier.
  2. Mutation to add a review to a movie.

I will not cover GraphQL Subscriptions which are a way to create and maintain a real-time connection with the GraphQL server. This feature enables the server to push instant information about related events to the client. You can read more about Subscriptions on the Apollo docs website.

Source Code

For reference, the source code of the application is available in my GitHub repository.
