There is a new pattern in town!

Just read this MSDN article about how the LightSwitch team modified (or extended) the MVVM pattern. Hold your breath it is called - MVVMVMMD or MV3.

Interesting approach, but if we want to change the view let's say add color - do we go back and change the IPropertyViewModel interface?

Slow TFS Performance

Recently the build time of one of our core projects on CruiseControl build server increased substantially. It went from ~8 min to ~20 min.

Upon investigation we found that the "get latest" step by CruiseControl was the bottleneck. I was also facing this problem in Visual Studio 2008, the IDE would hang for about a minute or two when ever get latest was issued. I thought the problem is with VS - probably the general (bad) impression of VS led me to this conclusion. But it was wrong to assume, the problem was with the TFS and how we map the several projects to our local folder.

We removed all unnecessary workspace mappings and also the root mapping. Now there is no local folder mapped for $. And the results are too good. Accessing TFS has become faster and overall performance of Visual Studio 2008 has also improved a lot.

Visual Studio 11 Beta - Error

Can you find out what is the problem in the screen shot? ;-)

What to focus on?

Today during the daily commute I was thinking about what technologies I should focus on. After thinking for a while I couldn't keep count of all things, so here it is in writing. :)

These are the areas I want to learn...but prioritization is needed otherwise I would end up learning nothing:

- WPF:In my day job most of the apps I develop are Windows (WPF) applications. So it makes sense for me to dig deeper into WPF. Going deeper into various MVVM frameworks is something I want to pursue.

- ASP.NET: We do have one BIG web application here. It's written nicely and architecture is quite cool. But it is still using WebForms approach, so I need get upto speed with ASP.NET MVC applications (also jQuery).

- .NET 4.0: Specifically parallel and async features - parallel LINQ, parallel task library, async/await. Dynamic feature.

- Unit Testing: especially Mocking tools

- Entity Framework: Although I am comfortable working with LinqToSql, EF is getting better with each new release. Nee…

The cloud is here.

Just read an article about the jobs that will be eliminated because of companies moving to cloud. My initial guess before reading the article was correct - the IT infrastructure support ppl. like network admins, mail server maintenance would be affected first. In fact, the company where I consult recently migrated to Gmail from Outlook and I already see less calls being made to support guys.

So the support group will be affected first and then the "custom development" teams would be affected. Companies whose core function is not IT or where it is treated as a cost center would more readily use cloud.

So how does it affect Microsoft developers like us? We do not have many options. If we want to stick to Microsoft then the only option is to learn about Azure. But I think it is time for a MS developer to leave his comfort zone and start evaluating technologies from other vendors.

Once again 'change' is on horizon. I guess this is how C++/VB developers might have felt c…
