Have considered about this requirement for a while and after some studies I found few options. Here are some:

I’ve just solved a problem about creating database. The application was working well until now we delete the old database to let Entity Framework creating a new one.

My application requires a unique id on some entities but it shouldn’t be the GUID (it’s good but it’s little long).

Today I integrate my application with Twitter and user now can sign-in by their Twitter account. It’s not so hard with support of the libraries Microsoft.Owin.Security.Twitter or Owin.Security.Providers. Beside, there are some issues soonly happens.

When upgrating an application to a newer version, it often requires to migrate its data (including delete/update some entities, add some new entities / configurations). At development phase, we often need to build some sample data for dev / test environments and reference data for production environment. DataUp comes to simplify this work, it was inspired by EF migrations & DbUp.

I got remote access issue of SQL Server 2K8 R2 on Windows Server 2K8 R2 which has firewall turned on. The fix took awhile so this post will note all steps that have been performed.

I deploy a sample application called SoftNews on AppHarbor. It works pretty well without any purchase as I still use free services (with small free RavenDB / Redis instances)

This post will explain how to automatically deploy database for an application in Octopus with EntityFramework.

It is possible to deploy new version of application to a specific environment on its new release creation. This straightforward method makes testing / deployment easier as the environment usually is for dev / dev integration.

This post explains all steps needed to install, work with Octopus Deploy that I have passes through. After some short of investigations, it’s really nice and should be in hands of .NET developers / production engineers.

This Mvc Extensions package provides common behaviors that almost applications need. Below are details of available features

The testing purpose of webapioauth.apphb.com requires to use a FQDN rather than using localhost as usual. So it requires to do some modification on IISExpress settings. Below steps are easily to make work.

I got an issue when deploying an application to AppHarbor cloud Platform regarding empty folder (!). It is a serious one because the application crash after deployment even with a experimental project.

EntityFramework contains ObjectQuery type which supports to perform advanced and dynamic query for entity with SQL-like syntax.

By default, WCF uses Windows to validate username / password. We can customize this process as well. This post will describe how to to authenticate a client, then authorize its behavior.

Asynchronous programming will help us improve performance and responsiveness of the app. The new architecture containing async and await keywords does almost difficult job and let developers write code similarly to synchronous code.

This post is about Messaging Patterns provided by WCF that I have learnt. It includes one-way, request/reply, streaming, and duplex communication.

The Rabbit.Foundation package is design to provide additional neccessary utilities for your application

Using XPath is an effecient way to query, filter in XML document. I will explain some practices using XPath.

XML is widely used in many applications and if familiar with it will be so helpful in coding activity. In this post we will go through a common scenario which produces string repsentation of a XmlDocument then you will see different methods with different behaviors they produce.

This post will drive you to create WCF Data Service and how to use it in your client application. A Windows Console application will be created to comsume the service by using its proxy. For Web application, it can be called by activating URL with HTTP method.

In this post I will share my little POC on Azure Cloud Storage including Blob / Queue. There are other ones like DocumentDB / Azure Tables / SQL Database, I had worked with but another post will cover these parts later. All code samples can be found in this repository on github

There are different data access technologies including ADO.NET, Entity Framework, WCF Data Services… with different benifits. Below is some key points of those technologies

To show how the application is layering and what it looks like, a layer diagram is best to visualize major components and dependencies using by code. It also helps us keep the code to satisfy with the design.

I have deployed application to Microsoft Azure and AppHabor but there are differences bitween two platform from the model to coding. It took me times, and I noted there for references.

Basis of mapping in Entity Framework, how to map a POCO to table and customize mapping using Fluent API.

Reading a series of posts Data Points - Coding for Domain-Driven Design: Tips for Data-Focused Devs have a look back to what I have done with.

I have involved in building a web application that deployed on a could platform using different database system from SQL to NoSQL database system. I will share here all steps we did to make it running.

My website is up and running well even it has not been implemented any dependency injection container. The result as this moment is that if a service has a dependency, it depends on the dependency implementation, they are coupling. A better design is that the service should depend on dependency’s abstraction. So I will apply Dependency Injection and bring a DI container into it.

This package has created to isolate serialization progress from depending on any serialization implementation. It provides extension methods to serialize / de-serialize any object at any layer of your application. You only need to configure one time at application entry point.

My story is that the website deployed on Azure needs to have Disqus function… It should be trivial because Disqus provide a nice plugin and just some simple configuration steps are required. It’s nothing but https is required. It impires me to create a new attribute called RequireHttpsInProductionAttribute.

Some helpful articles about all 3 patterns above. There are many links on the internet talking about these patterns but we do not need to read most of them, it may give you some confusion because each author explains in a different manner.

This post will describe some Markdown on the server side with .NET packages that I have experienced with and how to use them.

The WYSIWYG is very common and many websites support this feature. It often encodes user input into HTML format. There is another option using Markdown markup language. This post will explain in detail how to make it work and a custom JQuery plugin wrapps showdownjs.

The Provider Model is common in .NET Framework as we might know some like RoleProvider, ProfileProvider, MembershipProvider and so on. I want have something similar for cache, my application can switch to a different cache system just by changing some configuration element. So Provider Model seems a good approach to follow.

If an application will be deployed on Azure we can secure sensitive application settings (include AppSettings and ConnectionStrings) easily with just a little work for doing configuration and nothing is required to change on code.

Redis is a suppoer fast NoSQL data store, it can be used to cache our very high loaded data. This article will show in detail how to setup and configure Redis Cache on Azure and its usage.

Continuing on my previous post regarding EF-Azure for project IOnline, I need to adapt this requirement to: (1) Not using EF to count number of messages (total messages in the system and by categories) and (2) Use Dapper for the data access layer as a replacement. So I will have to create some stored procedures to make this works.

When working with EF Code First approach, we must update system database after modified model entities and of course, we must create a migration (or many migrations, depending on how are your changes). Later we can update the database manually or automatically (on the first read/write to the database).

The purpose of this task is to avoid spam post on your site (actually on your forms). We accept human post, not any robotic post ;)

Pagination !!! This task is very common as almost application requires pagination when listing data. So how is a good direction to complete this task? I did it again today and below is how it has been completed.

Microsoft Azure is a cloud-platform which enables us to host not only web-application, but also for long-running tasks such as data processing background task, periodic backup task…

When our public repository is not popular enough to be hosted on any CDN service, we can still reference to github url not needed to host it privately on the server get it locally on the server and having CDN benifit as usual (performance, bandwidth…)

We can enable content compression by code or by features provided by IIS. Also it can be enabled on both.

This blog was forked from JekyllNow with basic features. Some other features should be added to make the site richer in term of communication, content formatting… And below is some of them that I am thinking of.

I worked on a task to review references on all projects of a product. I saw many points to be improved and made alot of changes to make the code cleaner, easier to maintain, having better architect by applying abstraction, convert third-party dependencies to first-party… This is not only a pure coding task but also it requires code review & analysis, understanding on abstraction, architecture, design patterns and best practices.
