(The following are applicable to current Resharper and RIA Services releases (see post date). I'm sure it will be fixed in the future)

• Disable Resharper completely (Tools>Add-in Manager in Visual Studio)
• Disable Code Inspection and Intellisense of Resharper and let the Visual Studio do it:
  1. Resharper>Options in Visual Studio...
  2. Environment>Intellisense>General
  3. and Code Inspection>Settings

I run into an (one year) old article of Udi Dahan today. He explains how REST can be used to scale up an application, of course without the need to add additional hardware.

The idea is simple. If you have a SOAP web service that thousants of clients call, then a common practice would be to add caching behind it, in order to avoid hitting your database (or other resources) for each request. Common and cheap practice that works up to some extend.

However, If you use REST instead of SOAP for your service, then your responses are simple HTTP responses. Therefor you can add some HTTP headers in them, forcing the intermediates of the communication (proxy servers for example) to cache the response themselves. The result would be that when the client tries to hit your server, intermediate servers will return the cached response instead of hitting your server. Nice!!!

I'm trying to find my way into the Silverlight world lately. And one of the most predominant phrases in this world is Model-View-ViewModel pattern or else MVVM. This good old pattern suggests the separation of concerns in the UI tier into the three distinctive layers it's name indicates. I've never dealt with MVVM before and as I said Silverlight is also new to me. Therefore I'm trying to read as much as I can before digging into the code.

The most enlightening article I've read so far is Kathleen Dollard's "Applying Model-View-View Model in Silverlight". Kathleen explains how MVVM can be helpful, how to apply it in Silverlight, but also which MVVM promises can be elusive and which not!

Another article I read during my vacations was Shawn Wildermuth's.

I had a little problem today accessing a web resource and I decided to download Google Chrome "to get a second opinion". The last time I did the same thing was quite some time ago and since I got a new laptop recently I hadn't installed it yet. And guess what I found out? Ok, you don't have to guess... you read the title...

Yes, Google uses Microsoft .NET's ClickOnce technology to download and automatically upgrade Google Chrome in Windows Environment! If this is not a surprise what is!? Check it out...!

However... and thankfully at the end of the download there is an alternative way to get the traditional setup file, just in case something goes wrong. One would argue... what could go wrong? Well... in my case the clickonce installation did fail with the following exception: Win32Exception: The system cannot find the file specified! Now, now... don't start blaming Google or Microsoft about this!

I've blogged about Balsamiq Mockups in the past. Excellent tool that was really missing from my toolbox for a long time! I fully recommend it. I give Five Stars!

But the reason I'm writing this post is not about how useful and engenious it is but its about the latest blog post Peldi Guilizzoni (creator of the software) wrote. The title is "Donating Your Software: A Whole Lot of WIN!". Interesting way to look at software. Sure, being a member of WWF or Greenpeace or sending some money to Médecins Sans Frontières are noble gestures. But this is not the only way to "save this world"! Read the blog post!
