ASP.NET MVC - Authentication (Two-Factor, MembershipProvider, SimpleMembership)

Most web applications are using username and password for authentication. ASP.NET supports this concept since the very beginning.
With MVC 4 Microsoft also introduced the SimpleMembership, which makes authentication and user management more flexible.

ASP.NET MVC 4 - Blog engine based on Twitter Bootstrap

ASP.NET MVC - Generic filtering based on expressions

Recently I was asked to implement a reusable filtering mechanism in an ASP.NET MVC application. To be more concrete: A website shows a grid containing arbitrary data. The user should be able to enter a filter for each grid column.
The filters should be generated based on the type of the displayed objects. With that functionality, it is possible to filter every grid in the application with very little effort. Moreover I added a possibility to add custom search criteria.

About one year ago a created a blog engine which was based on ASP.NET MVC 1. Since then technologies have evolved.

ASP.NET MVC - SampleApplication based on Entity Framework 4.0

The intention of the MVCSampleApplication was to build a sample application using the latest .NET technologies.

The ASP.NET MVC application provides a simple guestbook, where users can register and post comments. Administrators may additionally edit and delete comments. Moreover a WPF based client is included, using the same services as the web application.

This article describes the key implementation aspects and overall architecture of the application. It does not contain a step-by-step tutorial explaining every detail, as you find many blog posts discussing all the technologies being used by this project on the internet. The goal here was to put all these technologies together in one application.

ASP.NET MVC - Routing of Legacy URLs

When you convert an existing ASP.NET application to ASP.NET MVC you will sooner or later want to handle legacy URLs.
Imagine an ASP.NET application containing the page "YourPage.aspx".
Now you want to redirect request to that legacy URL to the new MVC Action: "Home/YourPage".

I have looked at several implementations on the internet, but none of them was really simple.
Thus I implemented another solution which is really easy to configure.
