Sample code for the 2nd Preview Edition of Creating Mobile Apps with Xamarin.Forms.
Chapters of the book can be downloaded from http://developer.xamarin.com/guides/cross-platform/xamarin-forms/creating-mobile-apps-xamarin-forms/.
As of July 12, all solutions have been upgraded to Xamarin.Forms 1.4.3. Two additional projects have been added to every solution with the suffixes WinApp and WinPhone81. These projects target the Windows Runtime API in Windows 8.1 and Windows Phone 8.1, respectively.
Because Xamarin.Forms 1.4.3 is a stable release, there is no longer a separate windows-runtime branch.
The support of the Windows Runtime API is still in a early state and not working entirely well. In particular, the following problems will be experienced in the sample programs with the WinApp and WinPhone81 projects:
- Font sizes are somewhat erratic
Device.OnPlatformandOnPlatformdon't account for the two new platforms (but see below)- The SAP programs in Chapter 9 won't compile
- Some of the programs in Chapter 13 don't work (but see below)
To add the Windows Runtime projects to your own Xamarin.Forms solutions, see http://developer.xamarin.com/guides/cross-platform/xamarin-forms/windows/.
The Xamarin.Forms NuGet packages are not part of these projects. They must be downloaded for each project.
To avoid hassles, start by loading the NuGet packages for the two solutions in the Libraries directory, and building those two projects.
First load the Libraries/Xamarin.FormsBook.Toolkit solution into Visual Studio. Right-click the solution name in the Solution List and select Manage NuGet Packages for Solution. A notice should appear at the top of the Manage NuGet Packages dialog that says "Some NuGet packages are missing from this solution. Click to restore from you online package sources." Click the Restore button and then the Close button. Build the library.
Do the same thing with the Libraries/ElPasoHighSchool solution.
You can then load any of the application projects. For each project, again right-click the solution name, select Manage NuGet Packages for Solution and go through the same process.
For some programs, there are some differences between the code listings in the PDF book chapters and those in this repository: In Chapter 7, TextVariations is different because beginning with version 1.3.3, there is no longer a distinction between text as the content of the Label tags and text as content of the Label.Text tags. In both cases, whitespace at the beginning and end of the text block is trimmed.
When specifying a local namespace declaration in XAML, it is no longer necessary to include the assembly name. You can include it if you want, but it's been removed from the ColorListView program in Chapter 8, SharedStatics in Chapter 10, and StackedBitmap in Chapter 13.
The deprecated Font has been replaced with FontSize in MonkeyTap and XamlKeypad, both in Chapter 8.
The four programs in the section of Chapter 13 entitled "Platform-Specific Bitmaps" have all been enhanced to run on the two Windows Runtime platforms.
To accomplish this, a ForPlatform class has been added to the Xamarin.FormsBook.Toolkit library. This class is very similar to OnPlatform except that it has two additional properties named WindowsStore and WindowsPhoneStore. These properties allow a code or XAML file to access bitmaps from the two Windows Runtime projects.
Chapter 1 through 6, and chapters 19 and 23 have been upgraded to Xamarin.Forms 1.4.4. 6392. Two programs towards the end of Chapter 19 (ConditionalCells and ConditionalSection) previously did not work on Windows Phone, and the screenshot in the chapter showed a gray screen for that platform. The programs now run on Windows Phone with version 1.4.4.6392 and the chapter has been updated.
All the non-SAP solutions in Chapter 2 through 6 now exist in F# versions. These can be found in the FS directory of each of those chapter directories.
The two solutions in Chapter 2 were created manually and include F# versions of the iOS and Android startup projects (but C# versions of all the Windows Phone and Windows startup projects). The solutions in Chapter 3 through 6 were created from the normal Xamarin.Forms solution template for C#, and then an F# project was substituted for the PCL.
These should be considered "experimental" at this point. None of the F# projects run on Windows Phone 8, and others that use reflection have issues with the two Windows Runtime platforms.
