The document discusses Domain-Driven Design (DDD) with ASP.NET MVC and Entity Framework Code First. It covers challenges with traditional architecture like layers coupling and where to implement business rules. DDD is presented as a new default architecture where the database is not the primary focus, layers are loosely coupled, and business rules are within the application domain. Today's tools like ASP.NET MVC, dependency injection frameworks, and Entity Framework Code First are discussed. A demo is presented and conclusions recommend focusing on analyzing dependencies, designing the domain, and doing refactoring and unit testing.

Elements of DDD with ASP.NET MVC & Entity Framework Code FirstEnea Gabriel

Api patternOwen Rubel

The old API Pattern was designed in the 70's for centralized architectures and binds it's communication logic to it's business logic so that I/O cannot be shared with other services in an architecture without duplication. We will show a new API Pattern that fixes this issues by abstraction the communication layer away from business logic thus enabling sharing of I/O, better scale, less code, and faster processing as well as many other things.

4. features of .netPramod Rathore

The document discusses features and concepts related to .NET, including: - .NET supports object oriented programming and dynamic web pages. It provides efficient data access, code sharing capabilities, and improved security. - Source code in any .NET language is compiled to Microsoft Intermediate Language (MSIL) code.

Front-end architecture for cloud applications and PolymeruEngine Solutions

The document discusses front-end architecture for cloud applications using the Polymer web component framework. It describes problems with traditional one-page web apps related to low cohesion and high coupling. Polymer provides a component model for building cohesive, encapsulated components that can be composed together through HTML. It also supports responsive design through material design. The document argues that Polymer is a good choice for front-end frameworks because it is standards-based, has many contributed components, provides design tools, and is compatible with existing web technologies. It notes that the front-end plays an expanded role in aggregating and exposing APIs for cloud applications composed of microservices.

Flex vs HTML5Ray Wong

Adobe Flex allows for fast prototyping with readily available rich components and built-in functions, but is dependent on the Flash player. HTML5 offers new capabilities like offline storage, real-time communication, and device access using standards without plugins. While HTML5 provides better semantics and multimedia support, Flex has richer components and easier animation, but requires more coding for flexibility and debugging compared to HTML5.

The document provides an overview of a presentation on ASP.NET Web API and HTTP fundamentals. It includes sections on HTTP messages and URIs, routing and verbs in Web API, status codes, error handling, content negotiation, media type formatters, validating user input, and enabling OData queryable actions. The presentation aims to cover HTTP fundamentals through the lens of Web API, cramming attendees' brains with information on how to build HTTP-based web services using ASP.NET Web API.

ASP.NET Web API and HTTP FundamentalsIdo Flatow

ASP.NET Web API is the de facto framework for building HTTP-based services in the .NET ecosystem. With its WCF and MVC lineage, Web API brings to the table better architecture, easier configuration, increased testability, and as always, it's customizable from top to bottom. But to properly use Web API it is not enough to get familiar with its architecture and API, you also need to really understand what HTTP is all about. HTTP is the most common application layer protocol in the world, and yet, not many web developers are familiar with HTTP concepts such as of chunking, caching, and persisted connections. In this full-day tutorial, we will focus on designing and implementing HTTP-based services with ASP.NET Web API, and you will learn how to better use it to implement the features provided by HTTP.

Web API or WCF - An Architectural ComparisonAdnan Masood

ASP.NET Web API is a framework that makes it easy to build HTTP services that reach a broad range of clients, including browsers and mobile devices. The new ASP.NET Web API is a continuation of the previous WCF Web API projection. WCF was originally created to enable SOAP-based services and other related bindings. However, for simpler RESTful or RPCish services (think clients like jQuery) ASP.NET Web API is a good choice. In this meeting we discussed what do you need to understand as an architect to implement your service oriented architecture using WCF or ASP.NET web API. With code samples, we will elaborate on WCF Web API’s transition to ASP.NET Web API and respective constructs such as Service vs. Web API controller, Operation vs. Action, URI templates vs ASP.NET Routing, Message handlers, Formatters and Operation handlers vs Filters, model binders. WebApi offers support for modern HTTP programming model with full support for ASP.NET Routing, content negotiation and custom formatters, model binding and validation, filters, query composition, is easy to unit test and offers improved Inversion of Control (IoC) via DependencyResolver. You will walk away with a sample set of services that run on Silverlight, Windows Forms, WPF, Windows Phone and ASP.NET.

Sizing epics tales from an agile kingdomCodecamp Romania

The knights in the Agile Kingdom faced challenges sizing epics due to their variable size, complexity, and uncertainty. They developed two recipes - the Blue Recipe which involved planning poker and multiplication, and the Green Recipe which broke down an epic into user stories first. However, neither scale worked well for very large epics. They adapted by using a recently sized existing epic as a benchmark and rescaling. This allowed them to estimate the sizes of three sample epics as 5, 8, and 20 epic points, providing high-level sizing while addressing the issues of comparing variable epics.

DevOpsDays Atlanta 2025 - Building 10x Development Organizations.pptxJustin Reock

Building 10x Organizations with Modern Productivity Metrics 10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’ Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them. But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?

TrustArc Webinar: Consumer Expectations vs Corporate Realities on Data Broker...TrustArc

Most consumers believe they’re making informed decisions about their personal data—adjusting privacy settings, blocking trackers, and opting out where they can. However, our new research reveals that while awareness is high, taking meaningful action is still lacking. On the corporate side, many organizations report strong policies for managing third-party data and consumer consent yet fall short when it comes to consistency, accountability and transparency. This session will explore the research findings from TrustArc’s Privacy Pulse Survey, examining consumer attitudes toward personal data collection and practical suggestions for corporate practices around purchasing third-party data. Attendees will learn: - Consumer awareness around data brokers and what consumers are doing to limit data collection - How businesses assess third-party vendors and their consent management operations - Where business preparedness needs improvement - What these trends mean for the future of privacy governance and public trust This discussion is essential for privacy, risk, and compliance professionals who want to ground their strategies in current data and prepare for what’s next in the privacy landscape.
