Finding Performance Settings in DNN 9.x

30 Jan

With the recent release of DNN Platform version 9.0.0 & 9.0.1 I have been an increase in the requests for updates to my prior guides on locating the important performance settings since everything has moved to different locations. A major overhaul of my Performance Whitepaper is underway, however, I wanted to take a little bit of time to run through key settings for those new to 9.x. Consider this a high-level walkthrough of key concern areas.

Using Entity Framework with Legacy Databases

25 Jan

I find more people are interested in getting started with Entity Framework within their organizations. However, the various documentation and examples that exist don't necessarily give the best overall implementation solutions. I have worked with many people that have thought "we have a legacy database setup, we can't use entity framework" or "we cannot use migrations, so we can't use code first." Both are very common misconceptions, but something that isn't the case. It just takes a bit of work. In this post, we will dive into the specifics of implementing Entity Framework to a legacy database, where we cannot rename tables and other objects without substantial effort. A link to full code will be provided at the bottom.

Development Tools: NDepend & Quality

24 Jan

I often get asked which tools I use for development or reviewing of existing codebases. This question is often hard to answer directly, as every situation is a bit different. However, I thought it would be worth trying to revisit the tooling topics to help others possibly improve their environments by knowing the tools I find helpful. This post will be the first of a limited number of occasional posts on tooling. With the primary focus of my topics still being with ASP.NET, MVC, and performance. If you find these helpful, though, I'd love to get some feedback.

Applying A Methodical Approach to Website Performance Issues

11 Nov

Last week the folks at PostSharp where kind enough to host me for a webinar on website performance.  For those that have attended my various performance talks over the years I'm a firm believer in following a process every time to resolve issues.  In this webinar, I discuss the beginning portions of approaching website performance issues, tips that are helpful for those with existing applications, or even those that are starting fresh.
