For the last couple of weeks I have been working with client-side frameworks such as Kendo UI and Sencha ExtJS a lot. One of the requirements of my clients was server-side filtering, grouping and ordering of several grids and other components. The challenge here is that you don’t know exactly what information might be coming in: which field do you have to filter or sort, which direction, what operator do you have to use, etc. There is only one proper way to do this in C#: Expressions.
In one of my previous posts, I talked about using SQLDependency as a mechanism for detecting triggers on certain SQL queries. In this post, I’ll talk about how to use this mechanism to display real-time data in web applications using SignalR.
As part of my new professional website that I hope to release later this year, I thought it would be a good idea to dedicate a part of my site to this blog. Instead of choosing the rather traditional way of integrating blogs (e.g. embedded HTML snippets), I have chosen to take a look at its Web API. In this article, I will focus on one scenario: working with blog posts.
When I first read about MEF (Managed Extensibility Framework), I thought it was a great concept to create plugin-based applications, allowing customers to customize some behavior of the application for instance. Putting the whole concept into reality is something different, so in this article I will give a brief overview of the steps to take to get started with MEF.
As you might have read in my previous post, I used SQL schemas to partition data between tenants. Being part of the true definition of SaaS, a new tenant should be up and running within minutes without any human intervention. With my suggested approach, we need to do two things:
- Registering a new tenant
- Attaching users to the tenant
In this article, I am going to focus on the first item whereas the second one shouldn’t be a big deal if you are planning to create software as a service.
Until recently I have never had the time to concentrate on cloud application development. All of the projects (non-SharePoint related) I have ever worked on were dedicated to only one customer, so the multi tenancy challenge never came up. Although my own website is hosted on Azure, I realized I had to create my own project to gain some knowledge on this area. There are many books and web pages available regarding cloud development, but for a very good reason none of those give really specific examples: it all depends on what you want to achieve. In this article, I will cover one scenario that is quickly to implement with the knowledge many .NET developers probably still have, which is developing a **ASP.NET MVC application with Entity Framework which ensures storage in one database with multiple schemas.
