Garbage collector is a feature of CLR which cleans unused managed (it does not clean unmanaged objects) objects and reclaims memory. It’s a back ground thread which runs continuously and at specific intervals it checks if there are any unused objects whose memory can be claimed.

Note: - GC does not claim memory of unmanaged objects.

 

Note: - Garbage collector is one of the very important interview topics due to complexity of generations, double GC loop because of destructor and the implementation of finalize and dispose pattern. So please do go through the video of “What is Garbage collection, Generation, Finalize, Dispose and Idisposable?” to ensure that you understand the fundamentals well.


Different generations in Garbage collector (Gen 0, 1 and 2)


Generations defines age of the object.  There are three generations:-

  • Gen 0:- When application creates fresh objects they are marked as Gen 0.
  • Gen 1:- When GC is not able to clear the objects from Gen 0 in first round it moves them to Gen 1 bucket.
  • Gen 2:- When GC visits Gen 1 objects and he is not able to clear them he moves them gen 2.

Generations are created to improve GC performance. Garbage collector will spend more time on Gen 0 objects rather than Gen 1 and Gen 2 thus improving performance.

 

Note: - More the objects in Gen 0, more your application is stable.

One of the easy ways of doing validation in MVC is by using data annotations. Data annotations are nothing but attributes which you can be applied on the model properties. For example in the below code snippet we have a simple “customer” class with a property “customercode”.

 

This”CustomerCode” property is tagged with a “Required” data annotation attribute. In other words if this model is not provided customer code it will not accept the same.

 

public class Customer

{

        [Required(ErrorMessage="Customer code is required")]

        public string CustomerCode

        {

            set;

            get;

        }

}

 

In order to display the validation error message we need to use “ValidateMessageFor” method which belongs to the “Html” helper class.

 

<% using (Html.BeginForm("PostCustomer", "Home", FormMethod.Post))

{ %>

<%=Html.TextBoxFor(m => m.CustomerCode)%>

<%=Html.ValidationMessageFor(m => m.CustomerCode)%>
<input type="submit" value="Submit customer data" />
<%}%>

 

Later in the controller we can check if the model is proper or not by using “ModelState.IsValid” property and accordingly we can take actions.

 

public ActionResult PostCustomer(Customer obj)

{

if (ModelState.IsValid)

{

                obj.Save();

                return View("Thanks");

}

else

{

                return View("Customer");

}

}

 

Below is a simple view of how the error message is displayed on the view.

Post cache substitution is used when we want to cache the whole page but be also need some dynamic region inside that cached page. Some examples like QuoteoftheDay, RandomPhotos, and AdRotator etc. are examples where we can implement Post Cache Substitution.

 

Post-cache substitution can be achieved by two means:

  • Call the new Response.WriteSubstitution method, passing it a reference to the desired substitution method callback. 
  • Add a <asp:Substitution> control to the page at the desired location, and set its methodName attribute to the name of the callback method.

f1-copy-1.png

 

You can see we have a static function here “GetDateToString()”. We pass the response substitution callback to the “WriteSubstitution” method. So now, when ASP.NET page framework retrieves the cached page, it automatically triggers your callback method to get the dynamic content. It then inserts your content into the cached HTML of the page. Even if your page has not been cached yet (for example, it's being rendered for the first time), ASP.NET still calls your callback in the same way to get the dynamic content. So you create a method that generates some dynamic content, and by doing so you guarantee that your method is always called, and it’s content is never cached.

 

Ok the below example was by using “WriteSubstitution” now let’s try to see how we can do by using “<asp:substitution>” control. You can get the “<asp:substitution>” control from the editor toolbox.

 

f2-copy-2.png

 

Below is a sample code that shows how substitution control works. We have ASPX code at the right hand side and class code at the behind code at the left hand side. We need to provide the method name in the “methodname” attribute of the substitution control.

Debug and trace enables you to monitor application for errors and exception without VS.NET IDE. In Debug mode compiler inserts some debugging code inside the executable. As the debugging code is the part of the executable they run on the same thread where the code runs and they do not given you the exact efficiency of the code ( as they run on the same thread). So for every full executable DLL you will see a debug file also as shown in figure ‘Debug Mode’.

 

ove.png

Figure: - PDB files

 

Trace works in both debug as well as release mode. The main advantage of using trace over debug is to do performance analysis which cannot be done by debug. Trace runs on a different thread thus it does not impact the main code thread.

 

Note: - There is also a fundamental difference in thinking when we want to use trace and when want to debug. Tracing is a process about getting information regarding program's execution. On the other hand debugging is about finding errors in the code.

Web part is a window of information inside web pages which can be edited, closed, minimized, dragged and customized by the end user. Web parts are all about providing customization to the end user. Some of the customization features you can give to the end user by using web parts are as follows: -

  • You can add or remove control from the web page.
  • End user can modify the appearance of the control.
  • Controls can be moved to different location on the web page.

Figure “Web parts can be moved” shows how the end user is provided the ability to interchange the calendar and the login control on fly.

 

web1-copy-1.png
                                               Figure: - Web parts can be moved

 

Figure ‘Edit information using web parts’ shows one more magic of web parts. End user can edit appearance information of the web part which has a calendar control inside.

                                       Figure: - Edit information using web parts

 

The above customization either can be set at a personal level or for all users.

Figure : - 10 important namespaces


There are ten important namespaces / classes in WPF.

 

System.Threading.DispatcherObject


All WPF objects derive from the DispatcherObject. WPF works on STA model i.e. Single Threading Apartment Model. The main duty of this object is to handle concurrency and threading. When any message like mouse clicks, button clicks etc are initiated they are sent to the DispatcherObject who verifies whether code is running on the correct thread. In the coming section we will look in to detail how WPF threading works.

 

System.Windows.DependencyObject

 

When WPF was designed property based architecture was considered. In other words rather than using methods, functions and events object behavior will interact using properties. For now we will only restrict ourselves to this definition. In the coming section we have dedicated question for the same.

 

System.Windows.Media.Visual

 

Visual class is a drawing object which abstracts drawing instructions, how drawing should be drawn like clipping, opacity and other functionalities. Visual class also acts like a bridge between unmanaged MilCore.dll and WPF managed classes. When any class derived from visual it can be displayed on windows. If you want to create your own customized user interface then you can program using visual objects.

 

t3.png                                                  Figure : - Visual Object

 

System.Windows.UIElement


UIElement handled three important aspects layout, input and events.

 

System.Windows.FrameworkElement

 

FrameWorkElement uses the foundation set by UIElement. It adds key properties like HorizontalAlignment , VerticalAlignment , margins etc.

 

System.Windows.Shapes.Shape

This class helps us to create basic shapes such as Rectangle, Polygon, Ellipse, Line, and Path.

System.Windows.Controls.ContentControl

 
It holds a single piece of content. This can start from a simple label and go down to a unit level of string in a layout panel using shapes.
System.Windows.Controls.ItemsControl
 
This is the base class for all controls that show a collection of items, such as the ListBox and TreeView. 
 
System.Windows.Controls.ItemsControl

This is the base class for all controls that show a collection of items, such as the ListBox and TreeView. 

 

System.Windows.Controls.Panel
 

This class is used for all layout containers—elements that can contain one or more children and arrange them as per specific layout rules. These containers are the foundation of the WPF layout system, and using them is the key to arranging your content in the most attractive, flexible way possible.

“Services” are components, which expose well-defined interfaces, and these interfaces communicate through XML messages. Using SOA, you can build workflow, which uses interfaces of these components. SOA is typically useful when you are crossing heterogeneous technical boundaries, organizations, domain etc.

 

In .NET, SOA technically uses Web services to communicate with each service, which is crossing boundaries. You can look SOA, which sits on top of web services and provides a workflow.

 

SOA uses service components, which operate in their own domain boundary. Let us note some points of service:-

  • They are independent components and operate in their own boundary and own technology.
  • They have well defined interfaces, which use XML and WSDL to describe themselves.
  • Services have URL where anyone can find them and clients can bind to theseURL to avail for the service.
  • Services have very loosely coupled architecture. In order to communicate to service you only have to know the WSDL. Your client can then generate proxy from the WSDL of the service.

soa-copy-4.png

                                             Figure: - SOA Architecture

 

Above figure describes a broader picture of what service-oriented architecture will look like. The fundamental of SOA is a web service. In above diagram you can see there are two services available. One is the “Credit Card” service and other is “Address Check” web service. Both these services are provided by different company. Now we want to build a functionality, which needs to validate a credit card and check that addresses are proper. In short, we will need functionalities of both the “Credit Card” and “Address Check” service. Also, note the “Credit Card” service has its own business layer and DAL components, which can be in a proprietary language. It is very much possible that the whole Credit card service is made in .NET and the Address check is SAP implementation or JAVA implementation. However, because both the systems provide there functionality using Web services which is nothing but XML message communication. So we have made new service which sits like a FAÇADE on top of both the web service and performs both functionalities in one common service. You will see I have made a third service which sits on top of both the web service and consumes them. Also you can see that the UI part of the systems have access to Business layer and Web service of there system. However, the service which does both these check has only access to the Web service.

 

Note:- It’s beyond the scope of this book to discuss about SOA. However, just to keep you safe during interview this book has tried to clear some basics of SOA. I will really stress you to read WCF chapter of this book, which talks in detail of how Microsoft has visualized SOA.

In case you are not aware of how to post JSON using Jquery you can see the below interview question on the same http://www.dotnetinterviewquestions.in/article_how-can-we-post-json-to-server-aspnet-jquery-interview-questions_159.html

 

To convert a JSON string to a c# object we need to use the “JavascriptSerializer” class as shown in the below code.

 

“JsonString” is the string which has the JSON value and by using “Deserialize” we are converting the string to a c# object. Now this object which we receive is a collection of “key” and “value” pair which can be browsed and accessed in c#.

 

var jsonser = new JavaScriptSerializer()

var obj = jsonser.Deserialize<dynamic>(JsonString);

foreach (var x in obj)

{

      String strvalue = x[“value”];

}

By default, button controls in ASP.NET pages post back to the same page that contains the button, where you can write an event handler for the post. In most cases this is the desired behavior, but occasionaly you will also want to be able to post to another page in your application. The Server.Transfer method can be used to move between pages, however the URL does not change. Instead, the cross page-posting feature in ASP.NET 2.0 allows you to fire a normal post back to a different page in the application. In the target page, you can then access the values of server controls in the source page that initiated the post back. 

 

To use cross page posting, you can set the PostBackUrl property of a Button, LinkButton or ImageButton control, which specifies the target page. In the target page, you can then access the PreviousPage property to retrieve values from the source page. By default, the PreviousPage property is of type Page, so you must access controls using the FindControl method. You can also enable strongly-typed access to the source page by setting the @PreviousPageType directive in the target page to the virtual path or Type name of the source page.

 

Here is a systematic guide for implementing the cross-page post back using controls that implement the IButtonControl interface.

  • Create a Web Form and insert a Button control on it using the VS .NET designer.

  • Set the button's PostBackUrl property to the Web Form you want to post back. For  instance in this case it is "nextpage.aspx"

<asp:Button ID="Button1" runat="server"

PostBackUrl="~/nextpage.aspx" Text="Post to nextpage" />

 

When the PostBackUrl property of the IButtonControl is set, the ASP.NET framework binds the corresponding HTML element to new JavaScript function named WebForm_DoPostBackWithOptions. The corresponding HTML rendered by the ASP.NET will look like this:

 

<input type=”submit” name=”Button1” value=”Post to Page 2”
Onclick=”javascript:Webform_DoPostBackWithOptions(new webForm_PostBackOptions(“Button1”,”,false”,”Page2.aspx”,false, false))” id=”Button1”/>
