You should be aware that manipulating nullable instances does generate a lot of code . For example, see the following method:

Additionally, the root CA certificates of the CAs that issued the IAS server computer certificates must be installed in the Certificates (Local Computer)/Trusted Root Cer tification Authorities store of the VPN client computers.

If you are following the default route of using SQLite 3, you can ignore the Creating a Database with Tip MySQL sidebar.

C# public bool FundOrderFilter(FundOrder fundOrder) { return fundOrder.CustomerId == this.customerId; } ... FundAddedEvent fundAddedEvent = this.eventAggregator.GetEvent<FundAddedEvent>(); subscriptionToken = fundAddedEvent.Subscribe(FundAddedEventHandler, ThreadOption.UIThread, false, FundOrderFilter);

test/unit is not a requirement (although I recommend becoming familiar with using it before investigating

or a delegate s BeginInvoke . Calling a delegate s BeginInvoke method has known performance issues, and while Task objects require more memory, tasks run faster and are probably a better choice than calling a delegate s BeginInvoke method .

Briefly, here is what I did. First, I set the color to dark blue. Then I selected the Fill with Color tool and clicked the background to fill the canvas with this color. Next, I selected a lighter shade of blue and used the Airbrush tool to add some texture. Finally, I needed to add my logo text. I unchecked the Image Draw Opaque option so the text box wouldn t blot out the background. I used the Text tool to stretch a text area to cover most of the canvas, entered the text Joomla Jumpstart, and adjusted the font and size until everything looked decent. When I was done, I had something that wouldn t win any design awards (see Figure 2-42), but wouldn t embarrass my site either. I selected File Save As, set the filename as mw_joomlajumpstart_logo.png, and saved it into the same folder as the original logo.

All solutions are initially created as unmanaged. In an unmanaged solution, the components you add or create are stored only as references in the solution. For example, a custom entity you create in a custom, unmanaged solution will also appear in the default solution. The component does not exist within the unmanaged solution; it is merely referenced there as an associated component that should be included when the solution is imported or exported. Further, this means multiple unmanaged solutions can have a reference to the same component, and any changes made to that component will impact the other solutions that contain the component, regardless of which solution was used to make the changes. Those changes also will be included when any solution that references the component is exported.
