Subject: Get access to the MEF catalog
Posted: 20-May-2014 at 12:04pm

As with every dependency, you just need to make the catalog available through MEF so you can inject it where you need it. Here's how you can accomplish this.

    public class AppBootstrapper : CocktailMefBootstrapper<MainViewModel>
    {
        private ComposablePartCatalog _catalog;

        protected override ComposablePartCatalog PrepareCompositionCatalog()
        {
            // Hang on to the catalog
            return _catalog = base.PrepareCompositionCatalog();
        }

        protected override void PrepareCompositionContainer(CompositionBatch batch)
        {
            base.PrepareCompositionContainer(batch);

            // Add catalog to the MEF container
            batch.AddExportedValue(_catalog);
        }
    }

    [Export]
    public class MainViewModel : Screen
    {
        [ImportingConstructor]
        public MainViewModel(ComposablePartCatalog catalog)
        {
            
        }
    }

Hi,

I have a scenario with cocktail where I need to get access to the Mef Catalog to query the Part property (http://stackoverflow.com/questions/23497474/how-to-know-the-original-type-of-a-class-exported-as-an-interface-in-mef).

I need this information to implement the TargetGuard method of the INavigator. I check if an attribute decorate (or not) the class to allow (or refuse) the navigation.

I understand why it's not possible to publish this property as it's MEF dependant and the ICompositionProvider is "universal" for all type of IoC. But it's in some case really annoying to not have access to the catalog.
I also know I could write my own implementation of MEF and give it to cocktail but it looks it's a lot of work (need to redo the bootstrapper too) for just a small thing (in my point of view).

Could it be possible to add a class (dedicated to MEF) on Cocktail which, like EntityAspect.Wrap(), could wrap the cocktail MEF implementation and publish the Catalog ?

Right now I have a workaround but it's far to be clean. in the TargetGuard method, I create a new AggregateCatalog and fill it with the loaded assemblies. It would be nicer to use the catalog present in Cocktail

The IgnorePatterns are regular expressions. "^System.*" matches anything starting with the word System. The dot means any character. The expression you are thinking of is "^System[.].*" which will look for an actual dot followed by anything after the dot.

The IgnorePatterns are not new, but we've added new patterns over the years. You can also modify the list of ignore pattern. The discovery mechanism in DevForce is documented here: http://drc.ideablade.com/devforce-2012/bin/view/Documentation/discovery

We recommend for many reasons to adopt an assembly naming scheme that puts your own assemblies into its own namespace. Something like Company.AssemblyName.dll.

But my project was named SystemModule so the  "^System.*" pattern shouldn't hit because there is no "." after System. That is why I was confused and didn't look into name at first. Also this was in a recent update, is that ignore list a new thing? I ended up going with SysModule but I still think that SystemModule should have worked.]]> Wed, 09 Apr 2014 12:31:04 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=4672&PID=17465#17465 Community Forum : Getting, "No new content found in dynamic xap" after updating http://www.ideablade.com/forum/forum_posts.asp?TID=4672&PID=17464#17464 Author: mgood

John,
Not a bug, but following are the default IgnorePatterns to make sure we are not probing .NET system assemblies. If you name your assembly System.dll it's being ignored, because it machtes the "^System.*" pattern.

    private static List<string> BuildIgnoreList() {
      return new List<string>(new[] {
      "*.exe.config",
      "*.dll.config",
      "^IdeaBlade.*",
      "^System.*",
      "^Microsoft.*",
      "*.vshost.*",
      "^mscorlib.*",
      "^WindowsBase.*",
      "^PresentationCore.*",
      "^PresentationFramework.*",
      "^PostSharp.",
      "^EntityFramework.",
      "^Intersoft.*",
      "^Telerik.*",
      "^DevExpress.*",
      "^Infragistics*",  // Will be *2, 3, or 4.  SL assemblies are InfragisticsSLn.  WPF are now InfragisticsWPFn.
      "^WPFToolkit.*",
      "^Syncfusion.*",
      "^Janus.*",  
      "^C1.*", 
      "^PerpetuumSoft.*", 
      "^Xceed.*",
      });

Recently we updated to the latest version of cocktail and devforce. Everything went fine and the program starts. However, one of our xaps is not being loaded into the catalog and so none of the exports are being exported by MEF. Here is a piece of the output log:

IdeaBlade.Core.Composition.PartsCatalog:LoadCatalog : No new content found in dynamic xap SystemModule.xap
8 : 4/8/2014 4:28:46 PM :  : IdeaBlade.Core.Composition.PartsCatalog:OnRecomposed : Dynamic content added: SystemModule.xap, loaded without error

11 : 4/8/2014 4:28:46 PM :  : IdeaBlade.Core.Composition.PartsCatalog:OnRecomposed : Dynamic content added: FillingModule.xap, loaded without error

notice that the fillingmodule is loading fine but the systemmodule is not. I have tried everything I can think of to see what is different about the SystemModule from the FillingModule and the other 3 that are loading fine and I have not come up with anything. There is no errors in the output and we are not messing with any search patterns as suggested here:

Any ideas about what could be going wrong? We are using the CocktailMefBootstrapper and pretty much running it with everything as default. I also tried adding it as a reference in the main xap and the MEF still didnt pick it up. My only guess is that it is named System so it gets ignored but other than that I have nothing.

Thank you for your response, Marcel.

I using FireFox, Version 26.0; however, I have tested other Silverlight apps without issue.

A Silverlight page is actually loaded, but it is empty.

I will try building an app from scratch via the online instructions for the HappyHour application. Hopefully, I will be able to resolve the issue.

Thanks.

I am running VS 2010 using the Cocktail code Version 1_1_6.

The first installment of the sample HappyHour application (i.e., 01) compiles, runs, and the page loads correctly for both SL 4 and 5.

Although the additional projects (i.e., 02 - 08) build and run, the MainPage.xaml is not loaded nor is a Breakpoint tripped in the constructor of the MainPageViewModel.

I have reviewed the documentation on line but cannot find anything that indicates that I needed to add a Silverlight server, etc.

A "heads up" is greatly appreciated - thank you.

Looking at the future and what is going on in the world of .NET development, i would like to share my thoughts.
I came across mvvmcross and noticed that they lack the Cocktail part, but support some extra's we miss in cocktail. The ability to develop with PCL for multiple platforms and support for Xamarin.
Eisenberg's Micro Caliburn has already developed an alpha to support PCL development, but still lacks the Xamarin part.
Xamarin is investing a lot (strongly supported by Microsoft) to make a one-development environment for all platforms including android and IOS.
I think a PCL Xamarin-Cocktail version would be an excellent combination to develop Cocktail LOB programs that work with all platforms.

Did you follow the steps documented here to properly install and configure PostSharp 3.0? Also see the additional notes at the bottom regarding the assembly version. 

http://drc.ideablade.com/devforce-2012/bin/view/Documentation/postsharp3

Also, make sure the PostSharp Extension is properly installed in Visual Studio. PostSharp 3.0 does not work anymore without the extension installed.

Thank you for you answer.

We have stripped out the generation of Predicates (Filters on an Entity) and pass it now into a SearchService, that has a Count And IPager Method.


   /// <summary>
    ///     Predicate to filter the entities.
    /// </summary>
    /// <typeparam name="T">the Model/Projection to apply the filter on</typeparam>
    public interface IPredicate<T> : where T : IEntity
    {
        #region Public Methods

        /// <summary>
        ///     Applies the filter.
        /// </summary>
        /// <returns></returns>
        Expression<Func<T, bool>> ApplyFilter(Expression<Func<T, bool>> filters);

        #endregion
    }

Here is a sample implementation:

 public class CustomerFreeTextPredicate : IPredicate<Customer>
    {
        #region Fields

        private readonly string _searchTerm;

        #endregion

        #region Constructors and Destructors

        public CustomerFreeTextPredicate(string searchTerm)
        {
            _searchTerm = searchTerm;
          //  DisplayName = string.Format(Resources.CustomerFreeTextPredicate, _searchTerm);
        }

        #endregion

        #region IPredicate<Customer> Members

        public string DisplayName { get; set; }

        public Expression<Func<Customer, bool>> ApplyFilter(Expression<Func<Customer, bool>> filter)
        {
            return
                filter.And(
                    x =>
                    (x.CustomerName.Contains(_searchTerm) || x.CustomerNumber.Contains(_searchTerm)) &&
                    x.LegalEntityRefs.Any(
                        ler =>
                        ler.LegalEntityID.Equals(VisUser.LegalEntityId) && (ler.IsDeleted.HasValue && ler.IsDeleted.Value == false) &&
                        ler.IsActive.Equals(true)));
        }

        #endregion
    }


That all works, due to you fantastic implementaion of IRepository<T> !

Unfortunately, there is not. EF doesn't provide an inline count. You either have to run a count query or fetch the last page to know how many total records there are. That's just how it is. I recommend not to use the Total properties from IPager<> and instead just make a call to CountAsync() to get the total count and use that to calculate the number of pages etc. ]]> Wed, 20 Nov 2013 12:58:19 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=4605&PID=17250#17250 Community Forum : IPager<T> http://www.ideablade.com/forum/forum_posts.asp?TID=4605&PID=17246#17246 Author: cypher

We have started to Implement the IPagerRepository<T> with Cocktail.

The Implementation is straight forward with the help of you'r Documentation.

But we are really not happy, that we have to Query the complete last Page, in order to have the TotalAmount initalized in The 
IPager<T>

We have traced the Querys on SQL Profiler, and found out, that we have to fire three Querys 

1.(Count) 
2. LastPage
3. FirstPage

To initialize the IPager<T> to show the Pager.TotalDataSourceItemCount.

This is really sad, because we would like to query the database for the cound, if the first query starts.

Is there a Way for you to implement the IPager<T> from Cocktail, to have it initialize (Count) if the Pager.TotalDataSourceItemCount == -1 without loading the last page?

We really want to avoid, loading the last page, just to initialize the pager (get the TotalSourceItem)

We have a large framework, but something as simple as a project with a base bootstrapper, error handlers, anything else you need and then simply referencing that in a new project is a good start.]]> Thu, 07 Nov 2013 10:57:48 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=4594&PID=17216#17216 Community Forum : What is the best way to start a new Cocktail Project http://www.ideablade.com/forum/forum_posts.asp?TID=4594&PID=17215#17215 Author: gregweb

What is the best way to start a new Cocktail project?

If I start a new DevForce 2012 SL project, and add the Cocktail binaries through NuGet, there is a lot of functionality included in TempHire that needs to be migrated over.

If I start with TempHire itself, there is quite a bit that needs to be renamed.

I haven't found a happy medium between the two.

Greg, if you've verified that your client and server are both using the same DevForce and Cocktail versions yet you're still seeing the error, please let us know.

I think it has to do with versioning as I am now getting this same error regularly in other parts of the app with no changes made.

I am getting an error:

private async Task<List<WorkspaceEntity>> GetWorkspaces(String key) {
            var provider = new EntityManagerProvider<ShellEntityManager>();
            var uow = new UnitOfWork<WorkspaceEntity>(provider);
            var query = await uow.Entities.FindAsync(a=> a.ToolbarKey == key);
            return new List<WorkspaceEntity>(query);
        }

If I hard code a value for the "key" then it works fine. (It's just a simple string.)

This is the error that the BOS writes to the log:

Error System.ArgumentException: Argument types do not match at System.Linq.Expressions.Expression.Constant(Object value, Type type) at ....

This makes no sense to me. This project is using 7.1.0]]> Tue, 05 Nov 2013 11:29:26 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=4590&PID=17205#17205
