With the introduction of LINQ the difference between writing code for accessing a lists of objects in memory and accessing a list of data in an external data source like SQL is vanishing. Combining a in memory with a external list in a single query was not yet possible. With the introduction of .NET Framework 4.0 this has changed.

With SharePoint 2010 the amount of databases on your SQL server has grown quite a bit. By default most of these databases have their recovery model set to 'FULL'. After some time you will discover you're running out of space.

When you have a SharePoint farm and you want to use accounts from another domain you need a partial (one-way) or a full (two-way) trust between those domain. A full trust is not always desirable and there your problem begins. After setting up the one-way trust you can authenticate with an account from the trusted domain, but the SharePoint People Picker doesn't show any accounts from this domain. It has been documented by others before, but as I ran into this recently I'll give my summary how I fixed this.

The other day I attended a meeting where the presenter switched from a PowerPoint slide to demonstrate an application. When he made the switch it was quite obvious the beamer was setup to only display the 4:3 slides to the maximum of the white screen. Since his desktop was in a 16:10 resolution the application was falling of the screen on both sides. While I was preparing a presentation myself I wanted to be sure my presentation would be in the same resolution as my desktop as I would be switching between my slides and Visual Studio.

With the launch of Visual Studio 2010 this week a lot of people will start upgrading to the new version. After the installation was complete I noticed the Surface project and item templates were not available. In this post I explain how to get the entries in Visual Studio 2010.

Today the Microsoft Virtualization Team announced the availability of the new beta version of the Linux Integration Services for Hyper-V. In this post I will try the new features.

I wanted to use the new REST services in SharePoint 2010. But when I navigated to the ListData.svc service. I got the following error: “Could not load type 'System.Data.Services.Providers.IDataServiceUpdateProvider' from assembly 'System.Data.Services, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.”

Today the news broke Microsoft has extended the support for installations of Windows SharePoint Services 3.0 SP1, Microsoft Office SharePoint Server 2007 SP1 and Project Server 2007 SP1.

The Microsoft Surface is a Windows Vista computer running the Microsoft Surface Shell. This shell is by default localized for US English. It is possible to localize for other locales, but there is no configuration screen to set the desired localization. This post will summarize the different steps to localize the Surface shell.

If you want to develop for the Microsoft Surface you need a Surface device, but using the device to develop is not always practical, specially when there are more developers than Surface devices. The solution for this is to install the Surface SDK on you local development machine. This post will address some limitations you have to work around.

Now and again I come across code with hardcoded SharePoint IDs in it. Or scary loops matching a field, list or property name. SharePoint provides some classes containing the out of the box IDs, you only have to know they exist. I made an overview so nobody has to hardcode those pesky GUIDs, ContentTypeId's or property names.

Working on a Project Server project we discovered it's quite easy to get issues with data integrity when users start retracting and deleting timesheets. After discussing the issue with Microsoft they gave us a workaround which solves our problem.

The past couple of weeks I'm working with Silverlight controls embedded in SharePoint 2007. For one of the controls I need to retrieve the data using the Search Query Web Service. This was working perfectly in the development environment. But when deploying the control to the production environment it didn't work.

With the introduction of the August Cumulative Update for SharePoint 2007 (KB973399) we encountered “System.NullReferenceException: Object reference not set to an instance of an object.” on all pages inheriting from MySitePublicWebPartPage.

Stefan Goßner reminds us of the fact that support for WSS 3.0 SP1, SharePoint 2007 SP1 and Project Server SP1 will soon end.

I was having trouble with the clock in my Linux Hyper-V VMs. The time was constantly drifting forward. Using NTP only slowed the drift a bit down but often NTP gave up after several days.

I’m running Linux in Hyper-V VMs since the launch of the Windows Server 2008 RTM. It was quite complex to get performance and support for the network drivers. Recently with the launch of Windows Server 2008 R2 there are also new Linux Integration Components which also work for 2008 RTM. Here is the list of steps to install CentOS with these components.

Learn how I solved the problem of the Remote Desktop Client not using stored credentials due to a local policy setting, and simplified my RDP connections.

After having major, and unsolvable, problems with MovableType (MovableType was causing segfaults in Perl) for over half a year I finally switched to WordPress for hosting my blog.
