Generic Repository Pattern with ASP.NET MVC and EF provides a concise overview of the generic repository pattern and its implementation with ASP.NET MVC and Entity Framework. The generic repository pattern allows a single repository to handle data access for all models, reducing duplicate code, speeding development and enforcing consistency. The document outlines the steps to implement this pattern, including creating models, a DbContext, generic IRepository and Repository interfaces, modifying controllers to use the generic repository, enabling migrations and more.
Dapper caches query information like SQL statements and parameters to improve performance when materializing objects from query results. The cache is stored in a ConcurrentDictionary that is never flushed, so it could cause memory issues with dynamically-generated SQL. Queries using parameters are preferred since the cache key depends on the SQL and parameters, allowing caching of the execution plan. Buffering determines if all rows are loaded into memory before iterating. QueryMultiple is used for queries returning multiple result sets. Dirty tracking with interfaces allows Dapper to detect whether updates actually changed data to skip unnecessary SQL generation.
Learn about some of the new features in Laravel 5, with a focus on the command pipeline, including a few opinions about how to use the pipeline in the best possible way to enforce a solid separation of concerns.
This document discusses using interfaces and dependency injection to create a clean repository pattern with Entity Framework. It presents a typical dependency structure and issues with directly referencing data access layers. The solution shown uses interfaces to abstract data access and dependency injection to decouple layers. Code examples demonstrate implementing repositories, domain logic with constructor injection, and controllers without data dependencies. Benefits include flexibility to change data layers and performance.
An introduction to some of the concepts in Domain Driven Design with a specific emphasis on Repository Pattern, and how to apply them in Ruby on Rails.
This document discusses dependency injection and its benefits. It defines dependencies as components that an application relies on. Hard-coded dependencies are problematic because they are tightly coupled, not reusable, difficult to test, and complicate development. Dependency injection solves these issues by injecting dependencies through interfaces rather than having components directly instantiate their dependencies. This allows for loose coupling, reuse, testability, and flexible configurations of classes.
A Tour of EF Core's (1.1) Most Interesting & Important FeaturesJulie Lerman
?
This document summarizes key features and the evolution of Entity Framework Core. It notes that EF Core is a lightweight and extensible version of EF that works across platforms with .NET Core. It highlights composable APIs, cross-platform functionality, and modern software practices as themes of EF Core. The document reviews EF Core versions and features, differences between EF6 and EF Core, the roadmap for future EF Core releases, and resources for learning more.

This is a presentation about ASP.NET MVC 4 request pipeline, presented on Study Group meeting. It mainly contains analysis of MVC framework's source code.
Difference between wcf and asp.net web apiUmar Ali

WCF is Microsoft's unified programming model for building service-oriented applications that supports multiple transport protocols and message exchange patterns. It enables building secure and reliable services that can integrate across platforms. ASP.NET Web API is a framework for building HTTP services and is optimized for browser and mobile access. It only supports HTTP protocol but provides MVC features like routing and controllers. WCF supports advanced protocols like reliable messaging while ASP.NET Web API is best for resource-oriented HTTP services that need to support a broad range of clients. The document compares key differences between WCF and ASP.NET Web API across areas like protocols, hosting, description, and when to choose each technology.
Generic Repository Pattern with ASP.NET MVC and EF provides a concise overview of the generic repository pattern and its implementation with ASP.NET MVC and Entity Framework. The generic repository pattern allows a single repository to be used for data access across all models by abstracting data logic into a shared repository interface. This reduces redundant code, promotes code reuse, and makes the solution easier to maintain and develop quickly. The document outlines the steps to implement this pattern in an ASP.NET MVC application using EF for data access and data modeling.
Presentation from 2nd meeting of ASP.NET MVC 4 Study Group. It containts:
1. Route registration (also for areas).
2. How routing works?
3. URL Generation.
4. Route Debugging.
C# 6.0 introduced many new features including Roslyn, a complete rewrite of the .NET compiler that is now open source. It allows hosting compilers in memory and accessing parse trees from the IDE. C# 6.0 language features include auto property initializers, expression-bodied members, null propagation, nameof operator, and await in catch/finally blocks. Roslyn provides benefits like easier maintenance and new compiler-as-a-service capabilities that power features in Visual Studio. C# 7.0 continues enhancing the language with additions like tuples, pattern matching, and non-nullable types.
This document discusses advanced C# features including delegates, events, anonymous methods, lambda expressions, anonymous types, dynamic types, and extension methods. Delegates allow type-safe callbacks and are used to handle events. Anonymous methods and lambda expressions provide concise ways to handle events without standalone methods. Anonymous types define encapsulated data without associated methods, and are typically used with LINQ. Dynamic types have members that are resolved at runtime rather than compile time, without static type checking.
Real World Asp.Net WebApi ApplicationsEffie Arditi
?
This document provides guidance on building real world single page applications using various technologies including Git, AppHarbor PaaS, MongoDB integration, IoC/Dependency Injection, testing with nUnit and Moq, CI/CD, the Repository Pattern, and exception management. It discusses using Bootstrap.MVC for responsive design, Backbone.js as a client MVC library, and client-side session and authentication management. The document also covers building and deploying an app in the cloud using WebAPI which is self-hosted and flexible with content negotiation, and separating website concerns from the API.
