Resolving "Could not load type Microsoft.ApplicationServer.Caching.DataCacheSessionStoreProvider"

If you are using AppFabric and decide to swop out the ASP.NET standard caching with it you may run into the error:

Could not load type "Microsoft.ApplicationServer.Caching.DataCacheSessionStoreProvider”

The error will be pointing to the type of the custom session (line 5 below):

<sessionState mode="Custom" customProvider="AppFabricCacheSessionStoreProvider">
    <providers>
        <!-- specify the named cache for session data -->
        <add name="AppFabricCacheSessionStoreProvider" 
             type="Microsoft.ApplicationServer.Caching.DataCacheSessionStoreProvider" 
             cacheName="TailSpin" sharedId="TailSpinTravelId"/>
    </providers>
</sessionState>

The cause is that the application can’t find that class. To help it find it you need to add the following to the Configuration –> System.Web –> Compilation –> Assemblies:

<add assembly="Microsoft.ApplicationServer.Caching.Client, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
<add assembly="Microsoft.ApplicationServer.Caching.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

Why I like Visual Studio 2010? Undock Windows

imageVisual Studio 2010 has the ability to undock code windows by clicking and dragging on the code window tabs. This is a great feature and it is often touted for multi-monitor setups where you may want to have the form on one window and code on another window, or maybe two different code files open at the same time.

That is very useful, however that is not why I like this feature. I like the ability to undock the windows because it lets me view two different parts of the same file at the same time. Visual Studio 2010 and earlier have supported this using the split view option (image) but that means you lose half of your screen (like below).

image

Using the undock windows in 2010 you can use the Windows –> New Window option to duplicate the current window.

Then you can drag the second (or third, or forth) windows out and get a full screen side by side view which is GREAT for comparing code.

Cannot open VS project if Blend is used?

1I ran into an issue recently after reinstalling my laptop, where I couldn’t open a C# (WPF) project in Visual Studio 2010. Every time I tried it just grimaced at me and said:

Unable to read the project file 'Rule18.csproj'.

E:\Projects\Rule18\Rule18\Rule18.csproj(335,3): The imported project "C:\Program Files (x86)\MSBuild\Microsoft\Expression\Blend\3.1\WPF\Microsoft.Expression.Blend.WPF.targets" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.

Part of the cause is that previously I had Blend installed, and I had used it on this project to do some fairly complex things, in particular Font Embedding. However since reinstalling I had not installed Blend again.

This is caused the build target file not to be installed, and that caused the error.

How do you get around this?

The best solution is to install the FREE Blend SDK because that will put the build targets on the machine. Links for the SDKs:

However I didn’t have time to do this, so as a temporary solution (and definitely not a recommended solution): I opened the project file, and right near the bottom I found the Import for CSharp and Blend. I removed the Blend one, saved and reloaded and worked.

VirtualBox UUID already in use

I am playing around with using VirtualBox to run virtual machines and I ran into an issue trying to use a clone (copy) of a VDI file. The VDI file is the hard disk drive and it has a unique identifier in it it (UUID) and so trying to use a clone of one gives you the error: UUID of the hard disk is already exist in the media registry.

To solve it you need to run the following command to change the UUID of the file:

VBoxManage.exe internalcommands sethduuid [VDI file]

Example:

"c:\Program Files\Oracle\VirtualBox\VBoxManage.exe" internalcommands sethduuid

ALM in 2010

Here is the slides from my talk on Application Lifecycle Management in 2010 which I did for the Information Worker user group.

Here is the blurb for the session

Development is not just about writing code and pressing compile. It is a process, which starts long before code is written and extends long after the compile is done and this process includes a lot of management - this process is called Application Lifecycle Management (ALM).

SharePoint development is not immune to this and this presentation looks at what the landscape and tools are like for ALM in 2010 and how it relates to SharePoint development.

You can download the slides and the white paper from the IW site.
