Quite a few people at Tech-Ed wanted to know more about the various components of Visual Studio Team System (which we sometimes refer to as SKUs). For example, how does Team Foundation Server (TFS) fit in with the client SKUs? What are the differences between Visual Studio Team System Development Edition and Visual Studio Team System Test Edition? What is Visual Studio Team Suite?
These are very valid questions when you're considering which SKU to buy and since I'm not a sales or marketing guy I'll defer to some nice diagrams and comparisons already available on the web:
While we were demoing at Tech-Ed we were giving out trial versions of Visual Studio 2008 Team Suite, with some detailed tutorials (called Hands-On Labs) and they were very popular. If you'd like to try out the Virtual PC Image as well, download it here.
Some of my colleagues at Microsoft were interviewed for a panel discussion about various aspects of Team System which is worth watching to see where Team System is heading (Visual Studio Team System Panel - Meet the Team).
I also managed to catch a few sessions at Tech-Ed and one of the more interesting talks was about Visual Studio 2008 Tip of Day. Each day for more than 230 days now, Sara Ford has been posting blog entries with tips for Visual Studio.
UPDATE: I forgot to mention an interesting series on Channel 9 that I found out about while at Tech Ed. This Week On Channel 9 covers some of the highlights from Channel 9 blogs, articles and videos. The focus is on the developer, which works well for me. The current episode talks about PDC, Pex, Build Bunnies, UltraCam and the Live Agents SDK.
With Visual Studio 2010 we want to make it clearer when you are profiling your application within the Visual Studio IDE. To accomplish this we added a new control which we call ‘Profiling In Progress’ or PIP, which we show when you launch the profiler or attach the profiler to a running application.
Our goal was to show something simple and lightweight while profiling and to make a few simple operations possible. PIP in VS2010 is shown below:
Currently profiling. Pause profiling. Stop profiling or exit the application to generate a report.
The progress/spin control indicates that the UI is responding and there are two links:
After profiling completes, PIP changes to show that we are about to open the report.
Preparing to open report… This might take a while if your symbol server is slow or not responding.
I hadn't heard the term dogfooding used much before I started here, but it has already been explained so take a look here. The basic idea is that if you're not happy using your product (i.e. eating your own dogfood) then why should you expect your customers to be? Working at Microsoft gives you incredible scope to dogfood a wide variety of products.
As a Microsoft employee, I should be using Internet Explorer, Vista, Office, etc etc and I am. This doesn't necessarily mean I shouldn't run alternative products as well or when a Microsoft product doesn't provide the functionality I need.
As a Microsoft developer, I should be using Team Foundation Server for bug tracking and source control. I should be developing Visual Studio using Visual Studio. I should be profiling my code using VSTS profiling tools. Fortunately, I am, although not exclusively and probably not in some other parts of the company.
The main reason I think this is a good idea is because we get to feel any of the pain that customers do. We have extra incentive to fix any problems instead of ignoring them. We often catch problems early on before customers even see them.
I'll admit it, the process can be painful. The pain typically increases as you get closer to the bleeding edge of technology. For example, my Visual Studio dogfooding experience involves running the latest build of VSTS while developing. There are issues which delay my development, but facing these issues every day helps me drive improvements to the product. Imagine if your source control system went down - you'd want it fixed pretty quickly and that's just what we want from our TFS dogfood server.
Here's a few of things that I think need to happen for successful dogfooding:
If you're an application developer, are you using your own alpha/beta software before it is released to the public?
Last year my boss took a trip to sunny Orlando to present at Tech-Ed and to offer help and suggestions in the Technical Learning Center (TLC). This year I'm lucky enough to be attending with a couple of other folks (Habib and Tim) and since I'm not an official Speaker I'll be spending most of my time hanging out in the Application Lifecycle Management (ALM) demo station for Visual Studio 2008 Team System, Development Edition.
We've prepared a few demos covering things like:
We're also looking forward to discussing your specific scenarios so if you're at Tech-Ed and interested in diagnostic tools and solving performance problems we'd love to chat with you.
Join members of the Visual Studio Team System product group to discuss features available in Team Foundation Server, Team Suite, Architecture Edition, Development Edition, Database Edition, and Test Edition. In addition, discuss what's new for these editions for Visual Studio 2008.
We will be holding two sessions:
Join the chat on Wednesday, December 5th, 2007 from 10:00am - 11:00am Pacific Time. Add to Calendar | Additional Time Zones
Join the chat on Wednesday, December 5th, 2007 from 4:00pm - 5:00pm Pacific Time. Add to Calendar | Additional Time Zones
I'll be in the Wed 4 pm - 5 pm chat to answer any questions related to profiling. Another member of the profiler team will be online for the earlier chat.
I'm a member of IEEE and IEEE Computer Society and recently received requests to renew my subscriptions. I was pleasantly surprised to see that in 2008 student members of IEEE Computer Society can receive free software including Vista, Project, Visio and most interesting for me, Visual Studio Team System.
Both subscriptions come with monthly journals which are pretty technical and provide glimpses into various potential future career paths.
UPDATE: If you're a student in the US, Australia or a few other places you can also get Office Ultimate 2007 for up to 90% off the retail price.
I went to a meeting with Rico the other day and he showed us a few approaches he uses when solving performance issues. He is a performance engineer with many years of experience so it really was a case of watch and learn. This got me thinking about how people can best learn to use performance tools.
One starting point in this process is to consider my own experience learning a more mature dynamic code analysis tool - the debugger. Think back to the first time you ever started up a program running under a debugger. What was the first thing you did? My first debugging experience went something like this:
Sit back and think that's pretty cool - maybe I'll have to use a few less printfs to work out what's going on with my program. That's pretty much it. Gradually I learnt more and more about things like:
It took a long to discover some of these features. It took even longer to use them almost automatically while debugging.
Obviously the learning curve depends a lot upon the tool you use. Visual Studio tries to be more intuitive and easy to use than something like WinDbg, which is a command-line tool. Even with the ease of use of the visual debugger, you still need to know the typical debugging pattern (using breakpoints) before you can use the tool effectively.
Fewer people have used code profilers than debuggers and the tools are still less mature than their debugger equivalents, so it is harder for new programmers to profile their code than to debug it. In an ideal world we might have a 'fix my code' button or at the very least a 'highlight problem code lines' feature, but for now we need to develop patterns that developers can use to do this themselves.
What features would make profiling easier for you? Are we missing a fundamental concept (the equivalent of 'set breakpoint' in debugging land) that would make things so much easier?
The GM of Visual Studio Ultimate, Cameron Skinner, recently gave a talk at Tech-Ed 2011 about Application Lifecycle Management. It is worth taking a look at if you're interested in some of the new features being created for the next release of Visual Studio, such as the Team Navigator, shown below:
