If you've Firefox 3.6.4 or above installed on your computer and if you use it as your default browser, you'll probably meet some problems while trying to debug a Silverlight application in Visual Studio.

The Mozilla team has changed security settings for plugins.

I found the solution in the Silverlight forum (Thanks to MisterGoodcat!).

Here is what you to do :

• Type "about:config" into Firefox address bar
• Accept the warning (if applicable)
• Search for the entry "dom.ipc.plugins.enabled.npctrl.dll"
• Change its value from "true" to "false" (by double-clicking it)
• Restart the browser

A short post to prevent you installing an edition of Office/Outlook 2010 64 bits and better go to setup a 32 bits version.

A few days ago on my twitter, I shared this link : "Microsoft warns: Don't use 64-bit Office 2010"

Here is one good illustration of that…

I just tried to install the Microsoft Dynamics CRM 4.0 for Microsoft Office Outlook on a computer with Outlook 2010 64 bits and here is the message I get :

Time to uninstall Office 2010 64 bits and install Office 2010 32 bits on this computer!

Edit : Here is the official message from the CRM Team.

The new Enterprise Library 5.0 was launched a few days before and I decided to use this new version in my projects. One of the main application block I'm using is the Logging Application Block.

I went to use it in a WCF Service Library into Visual Studio 2010. Everything was fine until I decided to use a Database Trace Listener. Of course, I referenced the Microsoft.Practices.EnterpriseLibrary.Logging.Database in my project. But it always failed to run with this message:

"Invalid TraceListenerData type in configuration 'listenerDataType=\"Microsoft.Practices.EnterpriseLibrary.Logging.Database.Configuration.FormattedDatabaseTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging.Database, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35\"'."

Finally, I found that you need to work with the .NET 4.0 Full Framework and not only the Client Profile. Some assemblies are needed by the Database Trace Listener that are not present in the Client Profile (to learn more about the differences between the Full Framework and the Client profile, go here).

So, just target your project to the .NET Framework 4 and everything will be fine.

Imagine this simple custom list created in Sharepoint 2010 :

If you want to add an item to this list, here is the dialog that will be shown:

To easily customize this form:

Go in the List Tools > List in the Ribbon:

You can then choose the « Customize Form » icon :

Or, if you go in the Library Settings, you can use the "Form Settings" link.

Infopath will open with the form you asked to customize.

Here is my customisation (I will probably isn't it ?)

Now, when you create or edit an item in the list, here is the form that will be shown :

And if you browse your list in Sharepoint Designer 2010, you will find the template.xsn in the Item folder of your list.

Sharepoint server 2010 RTM was lauched 2 days before.

Here is my setup experience (presented through a small number of snapshots) of this new product in a VirtualBox environment.

The list of prerequisites is as follow :

Because I'm not in a domain and want just evaluate the product, I choose the Standalone mode.

Let the wizard configures your products.

Everything is fine, let's create your first site!
