monotouch bindings project to framework - xamarin.ios

What are the correct steps to creating a bindings project for a Framework versus a library? (Yes, they are close to the same thing, but NOT the same, the framework is a directory structure with header files, library and resources). These are what I've come up with, note that none of the Framework specific steps are documented as far as I can tell at the Xamarin web site (please prove me wrong).
Create the bindings project via MonoDevelop wizard.
Generate the ApiDefinition.cs and StructsAndEnums.cs files with btouch or by hand.
Copy the file from the root of the framework directory to lib.a (e.g., ArcGIS to libArcGIS.a) and add it to the project. It is important to note that the file without any file extension in the framework directory is in fact a library file.
?? Include framework resources ??
You'll notice that I get foggy at the third step. How to you add these resources to the bindings project? The large part of the bindings project links and runs fine, but I think it crashes at times because it is missing an expected resource.

You must (a) create a C# contract that describes the Objective-C contracts and how you want your projection into C# to look like, and (b) statically distribute the library with your project.
To kick the automatic population of the linkwith.cs you must rename the framework library (for example MyFramework) to use the library pattern (in this case, "libMyFramework.a")
Resources you have to select and flag as resources, they will be bundled directly into your app, and extracted when the library is consumed.

Auto compiling a dependent project without having a dependency on it

I'm developing ASP.NET MVC with extensive usage of Spring.net.
I have lots of services implemented in different assemblies. The purpose of using Spring and abstract interfaces is to decouple the application from the implementation of services. For example, the Data Access Layer is currently implemented by NHibernate, but the solution is designed to allow this to change.
So I have defined lots of Spring objects from foreign assemblies e.g.
<object id="RepositoryFactory" type="Org.Zighinetto.MyApp.NHibernateBasedRepositoryFactory, Org.Zighinetto.MyApp,NHibernate" />
As we all know, this works as soon as Org.Zighinetto.MyApp.NHibernate.dll example assembly either
Is in GAC
Is in bin directory
As of today, in order to allow quick debugging by hitting F5, I have set a dependency from the main project to all projects it depends on. As we all know, Spring is designed to allow us to cut the dependency between projects, but in this case I use dependencies only to tell Visual Studio to compile and deploy the DLL automatically, otherwise I would have to copy the right DLLs every time I want to debug my project.
The question is straightforward: given that I want to compile, at least in Release mode, my DLLs without unneeded dependencies, how can I make sure that Visual Studio, when I hit F5, automatically compile and deploys all of the Spring-required DLLs (which can be hardcoded by me somewhere, e.g. in a post-compile script) into bin directory?
In the Org.Zighinetto.MyApp example above, I want that once Org.Zighinetto.MyApp.dll gets compiled, VS compiles and deploy also Org.Zighinetto.MyApp.NHibernate.dll without having an explicit reference from .MyApp to .NHibernate
The dependency in you project file does not make the resulting assembly in any way dependent on these referenced files. You can safely have the dependencies there during development and compile your project.
The resulting output will still work when you swap out the assemblies that contain the implementation.

Orchard CMS Custom Module Project File

I have an existing solution (multiple projects, one MVC web project) that I'm trying to wrap into an Orchard module.
All documentation says that the web csproj should be at the root under my module directory (eg Modules/MyModule/MyWeb.csproj).
However, I have an existing solution structure where the sln file sits at the top level and each csproj file (and project content) sits in its own directory (the standard solution structure when you build a multi-project app in Visual Studio).
Is there a way I can tell my Module.txt file that the Orchard Module csproj is under MyModule/MyWeb/MyWeb.csproj? I'd prefer to not restructure the whole solution.
Thank you.
Note: As a point of clarification, it is not ~/Modules/MyModule/MyWeb.csproj but ~/Modules/MyModule/MyModule.csproj. The Folder name of the Module must match the file name of the project (before .csproj). This is enforced by the Dynamic Extension Loader, which requires ~/Module/{ModuleId}/{ModuleId}.csproj. (A similar approach is required for themes.)
The only potential way to do this is to write a custom module that follows the above that contains a custom loader. Within your module, create your own implementation of IExtensionLoader, and register it with Autofac. However, I don't know if it would work; I've never tried.
You will probably have an easier time reorganizing your solution.

Should third-party static libraries be included as an item in VC++ 2010 project?

I use third party static library (provided as a .LIB file without source code) in my project. For linking purposes it is enough to add it via "Properties/Linker/Input->Additional Dependencies"
This library is not used in any other project in the solution.
I wonder if I should add it as an item to project file itself. The advantages that I see: it will be immediately obvious that this project uses it and one wouldn't have to add it to version control system manually (anything that is a part of the project/solution is added automatically if you use something like AnkSVN).
The project in VCS must be buildable. It is impossible without the lib. So you should add it.

MonoDevelop: what is build action "Content" compared to "Resource"?

In my application all images, local HTML pages etc. are marked as "Build action Content".
I have just realized that there is also "Resource".
Which one should I use for images and which one for HTML pages to display in a UIWebView?
Currently I use images like this:
this.oImgLoginLogo.Image = UIImage.FromFile ( "Data/Images/ball.png" );
But in Monotouch.Dialog I see this line:
static UIImage arrow = Util.FromResource (null, "arrow.png");
But arrow.png is also marked as "content"...?
Puzzled.
What are the disdavantages/advantages of each option?
Embedded resources are embedded into the dll or exe file, and accessible from .NET reflection APIs. Content files are bundle resources and are copied into the app bundle (which is simply a directory), and accessible using file APIs or MonoTouch's Apple bundle APIs.
MonoTouch does support embedded resources, but they aren't straightforward to use from Apple-specific APIs, which are designed to use things from the app bundle. However, embedded resources may make more sense when you aren't dealing with MonoTouch-specific APIs, or when you're writing libraries that are portable to other platforms.
MonoTouch 4.0+ does support Content files in dll libraries - behind the scenes they're mangled into embedded resources when the library is compiled, so you can share it as a single dll file, then they're unpacked into the app bundle when the app is compiled.
My guess is that MonoTouch.Dialog was using embedded resources and not bundle resources because it's a library and predates MonoTouch 4, therefore the file marked as Content is a bug in the project.
In the .NET world, the difference is that during the build process a file marked as Content gets copied to the output folder, while a Resource file becomes part of the DLL itself.
AFAIK, MonoTouch doesn't includes resources into the build, because that doesn't exist in iOS, so that's why you always use Content. A final step then zips the directory with the executable and the content files into the .app file, which is how iOS expects it. The same thing is valid for MonoDroid.
The difference between MonoTouch and MonoDroid in the API exist because the idea of those frameworks is to translate, almost one-to-one, the APIs available in those platforms, instead of creating one interface that supports all platforms equally.

Why can BuildProvider be used only with ASP.NET website projects?

I was going to try Subsonic, you can generate DAL with buildProvider element in an ASP.NET website project. But I get curious why Web applications or windows applications do not support BuildProvider.
PS: I know for Subsonic there is one other option to use it with other than BuildProvider, but I just get curious.
It doesn't work because of the different way things are compiled in web application projects vs. website projects. From what I read on MSDN, it has to do with the fact that in web app projects, all your code files are compiled into a single assembly using MSBuild before deployment, but Build Providers are used to generate code that is compiled at runtime (from your App_Code folder).
In website projects, all of your code is compiled at runtime so it all plays nicely together.
You could possibly hook it into your pre-build event, and call the sonic.exe with the proper command line.
