There are a lot of Microsoft bloggers, literally thousands of them. When I first joined Microsoft I wasn't sure who to read. I've gradually built up a list based on interesting product and feature announcements and people I've met. Here they are:
That's just some of the Microsoft blogs I read. Are there other 'must-reads' that I'm missing?
I've been thinking about what some of the most important tools are for me while coding. Here's a few:
The Visual Studio 2010 MSDN documentation includes some more detailed examples (including screenshots) than previous versions. Here's a decent intro to profiling:Beginners Guide to Performance Profiling
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:

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.
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 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?
I've been here at Microsoft for more than 6 months so I guess you could say that I've passed through the Honeymoon Phase. By now the initial joy and excitement should be starting to wear off and I should be settling into a monotonous routine.
Well I'm happy to say that it hasn't happened so far. I'm still learning a lot, including things like:
I also like hearing about new features and products and being able to try them out before they're distributed to customers. Let's see how the next 6 months go.
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:
