GraphQL mutations are actions which we use to Add, Update and Delete data from a database. Until now, we have been executing only GraphQL Queries (fetching data) but in this article, we are going to talk more about data mutations in GraphQL. Input Types and Schema Enhancing for the GraphQL...

In this article, we are going to learn how to write advanced GraphQL queries and while doing that, we are going to show you how to handle errors and how to cache data inside a query. Furthermore, we are going to learn how to enhance our query (from a client...

In this article, we are going to learn how to set up GraphQL in ASP.NET Core application. We are going to use different third-party libraries to make this integration easier and will explain in detail how to use GraphQL elements (Type, Query, and Schema) to complete the integration process of...

In this tutorial, we are going to learn how to integrate GraphQL with ASP.NET Core Web API application, how to write types, queries, and mutations. Furthermore, we are going to learn how to consume the GraphQL API with the ASP.NET Core app and Angular client application as well. We are going to show you how to create different queries, how to use aliases and arguments, as well as fragments and directives while creating a GraphQL query. After finishing with this tutorial, you are going to have the knowledge to integrate GraphQL into the ASP.NET Core app and you’ll have no problem using Queries and Schemas to retrieve and mutate data from a server.

While we are working on a project, our main goal is to make it work as it supposed to and fulfill all the customer’s requirements. But wouldn’t you agree that creating a project that works is not enough? Shouldn’t that project be maintainable and readable as well? It turns out...

There's no doubt that Entity Framework with LINQ is great (I've certainly written enough articles about it). But Entity Framework comes at a cost. As Matthew Jones points out on his blog, using LINQ+Entity Framework adds time to each data retrieval compared to using ADO.NET's SqlDataAdapter. The cost is...

Some time ago we published an article with a comparison of Angular 2 and React. In that article, we showed pros and cons of these frameworks and suggested what to choose in 2017 for particular purposes. So, what is the situation in the frontend garden in 2018? JavaScript frameworks...

WEB FARM: A hosting environment consisting of multiple web servers is said to be a Web Farm. Usually a load balancer is used to tie together the web servers, which routes incoming requests amongst the servers within the web farm. And these incoming requests are routed in a variety of...

Try very, very hard to avoid using Response.Redirect(url), instead, use Response.Redirect(url, false). Response.Redirect(url), after writing a 302 redirect response to the response buffers, calls Response.End. This is very expensive. The alternative, Response.Redirect(url, false) is fast, but unlike Response.Redirect(url), the lines of code which follow the call to Response.Redirect(url, false) will...

When we launch the Notepad program in Windows, the program executes inside of a container known as a process. We can launch multiple instances of Notepad, and each instance will run in a dedicated process. Using the Task Manager application, we can see a list of all processes currently executing...
