I am new to IOC design. My company application has this following code:
My Question in regards to the below code:
1. I did not see .TheDefaultIsConcreteType.How does the below code knows which is the default type.
2. Also if someone can explain me what is that scan method in the below code doing?

We have an ASP.NET MVC site that uses Entity Framework abstractions with Repository and UnitOfWork patterns. What I'm wondering is how others have implemented navigation of complex object graphs with these patterns. Let me give an example from one of our controllers:
[code]....
It's a registration process and pretty much everything hangs off the POCO class Person. In this case we're caching the person through the registration process. I've now started implementing the latter part of the registration process which requires access to data deeper in the object graph. Specifically DPA data which hangs off Legal inside Country.
The code above is just mapping out the model information into a simpler format for the ViewModel. My question is do you consider this fairly deep navigation of the graph good practice or would you abstract out the retrieval of the objects further down the graph into repositories?
Does anyone have a working pattern for converting a GET-POST-GET pattern to asny?
I'm encountering the following issues:
1. You cannot mix Sync and Async action methods SubmitForm(), SubmitFormAsync(bool? confirm), SubmitFormCompleted() ... (because the resolver gets all confused ... it doesn't use the HTTP verb to decide who to target. BTW: I think that's poor design, or a bug)
2. Renaming the get method name to something else eg: SubmitFormConfirmation(), SubmitFormAsync(bool? confirm), SubmitFormCompleted() would be very awkward if it works ... because you have to doctor the <form markup to specify an action name.
3. You cannot give them all async names SubmitFormAsync(), SubmitFormAsync(bool? confirm), submitFormCompleted(), because the call just keeps malfunctioning. It sometime even behaves as if you are requesting a delete of something.
Can someone give an insight from an actually working sample.
Now that the next version of ASP.NET MVC is being prototyped and previewed (ASP.NET MVC 3 Preview 1 came out a couple of weeks ago), I wonder if we should call the attention of the Core Dev team (S Hanselman, Phil Haack and all) to this "feature."there a easy/non tacky way of associating subdomains → areas?Something like:
[URL]Also, whats the best accepted design pattern in implementing PRG pattern in ASP.NET MVC? I guess it should also get some official loving in MVC 3.
I wanted to know which all design pattern have you used in your application. Just wanted to see a general idea of most commonly used, popular design patterns. I was going through this site"
http://www.dofactory.com/Patterns/Patterns.aspx
and it has tons of design patters, I have heard about singleton and factory but not others.
So guyz which all popular efficient patterns are there and how would you determine which one suits your app. Can we make a app without a design pattern.
And lastly which one are the most simplest ones out there which are easier to implement.
I have a class which fetches the data from the database. Say First name, Last name , Telephone number etc and display it in my .aspx page. This data is common to all the users. So i would like to use Singleton pattern so that the object is not created again ,just use the created object for all the users. Can any one help me with the simple code snippet example.

View 1 RepliesI'm utterly new to APS.NET and in particular the MVC model...! I have a Telerik RadGrid control that I'm using. Until now (following NerdDinner) I was having the Model passed back to the view and this provided access to the various properties I wanted.
eg: Inherits="System.Web.Mvc.ViewPage<MySqlMvc.Helpers.PaginatedList<MySqlMvc.Models.Customer>>
.. lets me loop around the Model object and extract Customer data. This RadGrid control, however, needs me to use an EntityDataSource (hooked up via the designer). Does this have implications for maintaing the MVC pattern? I'm a little confused about how the EntityDataSource works in relation to my Model.EDIT: I do know there is an MVC version of the RadGrid but we also need the RadScheduler and a few others.. besides that, I'd still like to know the impact.
i'm new to asp.net MVC, and I'm trying to understand the service/repository pattern and how to best implement it.
I've followed the MVC Music store tutorial, and it suggests that the public partial class ShoppingCart implements an AddToCart method looking like this:
[Code]....
Now if I would like to use the service/repository pattern in a correct way, should I just replace the row "storeDB.AddToCarts(cartItem)" with something like cartService.AddToCarts(cartItem) and then just save the added row by calling cartService.Save() instead of shopDB.Save()? The methods AddToCart(...) and Save() in cartService then calls the repository that does the actual saving.
I have an MVC2 application with the following classes:
-OrderModel
-LineOrderModel
-OrderController
-LineOrderController
In the OrderController class I'm recollecting some values of a web form . Until now, I created instances of each order line (LineOrderModel class) and OrderClass inside of the Controller.
I was trying to create a OrderFacade class in order to encapsulate the different things to do when creating an order.
So in that class I created a method like this:
public void saveOrder(int idProvider,decimal? price)
{
// Here I create instances of OrderModel and LineOrderModel
// and assign their properties
}
but my problem is I don't know how to pass all the order lines captured from the web form.
I think it doesn't make sense to create and pass to that method a List with orderLines class (because the point of this is to operate with the Facade, not with the class directly)
How could I encapsulate the different lines (all with properties like numberUnits,idProduct ...) into a List of generic objects, each one with these properties?
Maybe something like a List<List<object>> ?
I am using asp.net and c#.
I have a some classes. Some of the classes are having same methods insert, update and delete.
Each insert will insert different data to different table. (same for update and delete). What type of pattern can be applied for this kind of class.
which is the best for starting up a new project in ASP.Net MVC? I have added this question as to know what are the different options.

View 1 RepliesI have a web application where I would like to pull user settings from a database and store them for Global access. Would it make more sense to store the data in a Singleton, or a Session object? What's the difference between the two?Is it better to store the data as an object reference or break it up into value type objects (ints and strings)?

View 4 RepliesHow can we use ObjectDatasource with MVP pattern in ASP.NET application?
In 3-tier architecture there is no Data Access layer,.in place of DAL, I want to consume Web Services and Request and Response is in the form of Custom objects i.e. BusinessRequest and BusinessResponse class type.
Is it possible to merge all these in one solution, MVP, 3-tier web application, No DAL, Only consuming Web Service , BAL, ObjectDataSource, GridView?
I would like to use MVP pattern and add a presenter layer in my web app. EX;- for filling the data in page I am doing like this.

If I add a presenter class, Do I need to move this code in presenter layer?
So yesterday my mate and myself had this duscussion about the architecture of this e-shopping website that im developing. Note that I work with ASP.NET for this. He was quite surprised to learn that I do not keep the Items added to the shopping-cart in an ArrayList or other Generic list but rather i insert them straight to the database using LINQ To Entities. Could I pass only for this web app and not use n-tire or should I do as my friend suggested which is, have methods that perform updates, deletions etc..
View 2 RepliesI am a asp.net developer and don't know much about patterns and architecture.In my web applications I use 4 layers.Web site project (having web forms + code behind cs files, user controls + code behind cs files, master pages + code behind cs files)
CustomTypesLayer a class library (having custom types, enumerations, DTOs, constructers, get, set and validations)
BusinessLogicLayer a class library (having all business logic, rules and all calls to DAL functions)
DataAccessLayer a class library( having just classes communicating to database.)
-My user interface just calls BusinessLogicLayer. BusinessLogicLayer do proecessign in it self and for data it calls DataAccessLayer funtions.
-Web forms do not calls directly DAL.
-CustomTypesLayer is shared by all layers.
I though it may be MVC or MVP but pages have there code behind files as well which are confusing me.
I am using ASP .NET and C#, and using the code-behind-pages concept.I am trying to implement a business delegate pattern in ASP .NET to reduce coupling between the presentation and business tiers.I want to have several ASP pages send information (through asp buttons clicks) to a "business delegate" ASP page, which will in turn send the necessary information to a C# method.The problem is that each button_click event in ASP .NET is directly tied to a C# method. I am having trouble understanding how to separate the presentation and business logic because of that.
View 1 RepliesI've been using MVC for the last year and unfortunately I am stuck adding features to an existing web forms site. The site makes heavy use of inline SQL and it is kind of all over the place. Using an ORM is not going to happen either and wouldn't address the problem of keeping queries all in one place.
Can the Repository Pattern and Service layers also work well with classic asp.net web forms?
I am building an application using asp.net mvc, DI, IoC, TDD as a bit of a learning exercise.
For my data access I am using the repository pattern. Now I am looking at membership and how this can work with the repository pattern. I am currently using a Linq to Sql repository but don't want to be tied to SQL Server for membership.
Secondly, I am looking to split out membership into a number of services:
AuthenticationService - identify the user
AuthorizationService - what can they do
PersonalizationService - profile
The personalization service will be what really defines a "customer" in my application and each customer will have a unique id/username that ties back to the AuthenticationService - thus, allowing me to use the default ASP.NET Membership provider, roll my own or use something like Open ID.
Is this a good approach? I don't want to reinvent the wheel but would rather these important parts of my application follow the same patterns as the rest.
I just started working on one of the application, bascially its some maintanence work. I see from the application that Facade pattern has been utilized as I see Class Library projects named as Business Facade, Data Facade.
Though I am not redesigning this, but just wanted to know what this pattern is, a simple explanation, use, real world example should be good enough. The application is basically a banking app. I know its diff but if anyone can give me some hints/points as in why the designer chose this pattern (banking app).
YARPQ - Yet Another Regex Pattern Question:
What I am trying to figure out is how to use a custom delimiter, single character or set of characters, to wrap a block of text inside a larger body of text and then pull that text out via regex. I have successfully done this with a single instance of wrapped text. If I have multiple instances, it blows up. Here is an example.
This would be my text block with the internally wrapped text:
[Code]....
When my current regex runs on this block, the greedy nature gives me a match starting with my first wrapped block delimeter and ending with my second wrapped block end delimeter. So my regex of @"#Delim(.*)#EndDelim" doesn't work in this instance. I am trying to figure out how to exclude the #EndDelim from my grouping. Simply using ([^#EndDelim]*) doesn't work as it tells regex to ignore the individual characters inside the brackets and not the actual word so this breaks if I have any of those characters inside my wrapped block of text.
I am probably making this harder than it needs to be. Does anyone know of a good solution or how to ignore entire words in regex?
