The Productivity Power Tools is a super cool pack of extensions that will make Visual Studio 2010 tremendous fun, and make you more productive. Now the team has announced a new version. This lets you turn individual tools on and off, so if you love Highlight Current Line and Go To Definition, but hate Align Assignments, you're in luck:
There's also new tools in the pack. Solution Navigator "merges functionality from Solution Explorer, Class View, Object Browser, Call
Hierarchy, Navigate To, and Find Symbol References into a single view" according to Adrian Collier, and lets you pin tooltips of information near the place in the code where you use them, pops up previews of image files when you hover over them in the tool pane, and just generally reads your mind to make you a happier and more productive developer.
This package had me at "Go To Definition" but these additions make it even more of a must have. You can install right from within Visual Studio 2010, too. Choose Tools, Extension Manager. Click Online Gallery. In the search box type Productivity.
When you see this dialog, click Install:
You'll be prompted to restart Visual Studio:
Click Restart Now and wait a sec. And that's all it takes! You really will love it.

Would you like your machine to use up to 25% less power? Are you on XP now? You can see a big improvement by switching to Windows 7. There are some other things you can do too, like changing some drivers, but those are probably a bit difficult for most people. We have a number of machines kicking around the office that we've left on XP because they're really just file and print servers, people don't use them directly very often, so the obvious UI benefits of Windows 7 didn't seem relevant. But lowering the power bill is relevant, right? Or, if you're out and about with your laptop, having the battery last longer is relevant, right?
Here's the blog
where I found some numbers ... it's a summary of a longer whitepaper
and you should probably read that too.

I mentioned I've been recording videos. That's because I'm doing another Pluralsight course. This one is on Customizing and Extending Visual Studio. About half of it is live already:
- Overview of Visual Studio 2010 Extensibility
- Why write extensions for Visual Studio?
- Visual Studio Macros
- Visual Studio Snippets
- Getting and installing extensions for Visual Studio
- The Visual Studio 2010 SDK
- Visual Studio Start Page
- The VSIX Format
There's more to come, of course - I'm about half done. I'm really enjoying this material. You can get your work done a lot faster if you tweak Visual Studio to meet your needs. It doesn't have to cost you money and it doesn't have to cost you much time. Take a look!

Pluralsight On-Demand! now has a second Windows 7 development course
. I'm happy to see this - Eric
and I co-ordinated while I was doing my course
. In the first modules that are online now, he tackles topics that I did not - Restart and Recovery, Task Dialog, and Search. Feel free to use both courses to make yourself a better Windows developer!

I've had a chance to watch a number of the videos from the Windows Summit - an online event to help you with Windows development of all kinds. You can learn more about it and register at the main summit site, or check the lists of sessions for developers. The only trick is that once you've registered, you need to go to a different site to actually watch the sessions. Once you know that (and there is a link on the main site) you're all set.
I've been getting "Windows 7 for Developers" training since before the first public beta, so I had seen a lot of this before. But several sessions were noticeable improvements from the way that material had been covered in the past, and none of them were poorly done, so I recommend this as a way to learn the concepts that are important to anyone writing for Windows 7, and to learn the advantages that Windows 7 can offer to you as a developer and to your users.
I saw three different approaches to code in the sessions I watched:
- Full on demos with Visual Studio involved
- Code on the PowerPoint slides, and links to resources that include code demos
- Mention the name of the API but don't show how to use it
I also saw a mix of native and managed code, with some sessions going all the way to the native side of the spectrum and some all the way to the managed side. Most of the sessions mentioned the Code Pack
, of course, and call out a link to it in their resources.
Even if you know all about the taskbar, maybe you could learn about power management, or background services, using sensors, or writing location aware applications? It's really worth taking a look around.

Here is something I've been asked more than once, and seen asked on various forums as well. I'll paraphrase rather than quote one specific asker:
We have an application written 15 years ago that's been working flawlessly. But when we run it on Windows 7, the users can't find the files it writes. Worse, there are no error messages, so they think they've saved the files, but when they go to C:\Program Files\MyGreatSoftware\UserExports - the files aren't there!
Often, the question trails off into a rant about how sneaky and mean Windows 7 is to somehow prevent access to Program Files but not give error messages. The rant might also include a paean to how amazing the lost files were and how many workyears of productivity have been lost now that these files cannot be found, and why this means you can't trust Windows to do something as simple as write a file to the hard drive. Sometimes, the asker has established that this is related to UAC and they are recommending everyone turn it off to avoid this disaster. I thought I would make some less drastic suggestions.
First, your files are not lost. A few people know this, but they then claim the files are almost impossible to find and no end user will ever find them. Let's tackle this one first because if you know this trick you may be able to get by without changing anything else about your application. Tell the user to go to the place they expect to find the files, say C:\Program Files\MyGreatSoftware\UserExports. Then have them look in the toolbar for a button that says Compatibility Files. Click it. Ta-da!
Ok, now the next thing is, why the heck are your files being written there? Because you are trying to write to a protected area and you don't have a manifest. You have several things you can do about this, and they boil down to two main things:
One, don't write to a protected area. You can get this by installing somewhere other than Program Files (not a good idea) or by changing the application to write to a better place. Two, get permission to write to the protected area. This means running as administrator. Train the users to right-click Run As Administrator when they run the app, or train them to set the Compatibility Settings for the app (neither very likely) or ship the application with a manifest that includes requireAdministrator. Now matter how you arrange this second thing, your users are not going to like agreeing to the UAC prompt every darn time. So really, that brings you back to number one, don't write to a protected area. Use AppData instead - there's a simple function call to get that path on any machine (including older XP machines) and you'll be in fine shape. If you think your users can't find that, and the files are for the users and not just some internal settings, then use a folder under Documents - again, there's a simple function call that will get you the path.
If virtualization makes you nuts - that your code thinks it's writing to C:\Program Files\whatever but really it's writing somewhere else, and the OS is cheerfully lying to it and saying all the writes succeeded - then put a manifest on your app. Doesn't matter whether it's requireAdministrator or asInvoker. Doesn't matter whether it's embedded (VS will embed them for you from 2008 on easily, and there are tools that do just manifest adding) or just a file of XML in the same folder as the exe. Once the app has a manifest, virtualization stops. Of course this may mean the users get all kinds of Access Denied errors that they don't like. Now you see why virtualization was invented.
Should you rely on it? No. For one thing, it may go away in some future version of Windows. And it goes away when you add a manifest, which for many people happened when they migrated to a new version of Visual Studio. What you should do is understand it, including how to find the virtual store, so it doesn't make you quite so crazy.
Now go turn UAC back on,

There are two services I use not just every day, but many many times a day. One is email and the other is Twitter. Facebook and StackOverflow also get their share of attention, but one thing that sets Twitter apart from Facebook and StackOverflow is the proliferation of clients you can use to access it. You can go to the web page, and do it all in a browser, or you can get any of the many clients available to give you a richer experience. The same is true for email - I can use Outlook or I can use OWA and do it all in a browser.
Recently I found myself facing a full week away from home and the office and with no way to get a VPN although I had great internet access. I could listen to CBC radio and watch Canadian TV but I could not bring my email in Outlook. The first day was ok, but not great. I found myself wanting to email people, and I had to open Outlook to poke around and get their email addresses, then paste them into the OWA new message. It was so different from the usual fast-as-thought process of typing the first letter or two of their names and pressing tab. I also had to delete my own spam, because I don't like server-based spam filters and have been really happy with my client-side spam settings in Outlook. The little preview windows weren't as informative as I wanted, my old appointments weren't showing up, there was no to-do bar, and deleting messages or waiting for the new window when I replied to messages just took too darn long. By day 3 I was about insane. Finally my favourite sysadmin (who I was smart enough to marry almost 30 years ago) got Outlook-over-http working for me and I could go back to normal.
I was utterly astonished at the effect on my mood that not having my client application had on me, and the effect of getting it back. It was very distinct and unmissable. The browser solution just wasn't good enough for me - and OWA is an amazing feat of engineering, with a way richer UI (delete key works, F keys work, etc) than most browser-based solutions. It got me thinking, once my cheerful mood had let me catch up on some outstanding work, about client apps in general. Why do I only use Twitter in a browser? I've tried a whole number of clients but I always end up back in the browser. I think it's because clients have to be well-designed to work well. If they hog resources, jump in your face too much with focus stealing or balloon tips, or insist on being sized a certain way then they don't get a chance to show you their good side. Twitter is pretty young and I don't think we've really had time to winnow the good client features the way we have with email. With that in mind, and believing a good client really will be a better experience, I've decided to try MetroTwit. I've heard really good things about it and I honestly believe that client apps make more sense for these sorts of information feeds. So far, I like it. I get toast for new tweets, a new tweet counter as a taskbar overlay icon, and such a delicate consumption of my CPU and disk activity that I can't tell if it's running or not.
You might also be interested to hear why the developers chose WPF, and what that led to for the team:
over just a couple of months, what we’ve achieved with MetroTwit was simply not possible without
WPF considering the few precious midnight hours we put into it on most days.
According to the rest of the team (the real developers), apparently I owe much
to data-binding which I’ve been told is nothing short of a miracle.
If you have a choice of using a browser or using a client app, which do you choose? Is it always the same or does it vary with the business purpose you use it for? While we don't represent our users exactly, we can still learn from our own personal choices and our emotional reactions to software.

I'm not sure when this started, but DevX has a whole area for Visual Studio 2010 articles. They've got handy links to download a trial and a training kit, walkthroughs of creating extensions (a simple blogging one, and adding your own language to the IDE), and lots more. It's a combination of articles, webcasts, and downloads that cover not just Visual Studio but some of the things you can create with it and what's new in related tools. Of course I've seen some of the material before, but that just shows that it's comprehensive. Take a look around!
