WCF Reliable Messaging makes web services more reliable. It addresses the following problems:

A call to a web service does not make because the networks are not perfectly reliable as they suffer congestion and may drop signals. OR the service response does not make it back to the client. If I make multiple calls to the web service and the calls do not reach to the service in the same order that i made them there is a problem. WCF reliable messaging makes sending messages reliable and ordered over unreliable network.

When we create a Web API, it creates a default route “api/{controller}/{id}” in WebApiConfig.cs file. Action name is not defined in the route.

Web API by default serves to HTTP verbs Get, Post, Put, Delete with optional parameters.

Web API identifies the action with http verbs. If we have more than one action method with same HTTP verb and same parameters then it is very difficult for web api to serve the correct method. So it returns the error message “Multiple actions were found that match the request”.

To resolve this confusion we have to define “action” in the route as “api/{controller}/{action}/{id}”.

Now it will be able to identify AddEmployee action method.

We are creating a SQL Server Table-value function to get weekdays between two dates. Logic is simple as DatePart(dw,Getdate()) returns integer value of the day. Sunday is equivalent to 1 and Monday is equivalent to 2 and so far. As we know weekdays are from Monday to Friday. So all the days between 2 and 6(including these two) are weekdays. Here is the code for the same. Create function dbo.getWeekDays(@startdate date, @enddate date) returns @temptable TABLE (weekDays varchar(100),Name Varchar(100)) As Begin Declare @weekday date While @startdate <= @enddate Begin IF DATEPART(dw,@startdate) between 2 and 6 Begin Insert into @temptable(weekDays,Name) Values(@startdate,DATENAME (DW, @startdate)) End SET @startdate = DATEADD(DAY,1,@startdate) End Return End Query to get weekdays SELECT weekDays,Name from dbo.getWeekDays ('01/01/2016', '01/31/2016')

@Html.Partial

@Html.Partial returns string. Syntax : @Html.Partial(“Partial View Name”). Pass model with Partial method Syntax : @Html.Partial(“Partial View Name”, Model). It is slower as compared to @Html.RenderPartial. It’s result can be manipulated before rendering to the output stream. Manipulation : @{ var data= Html.Partial(“Partial View Name”); } @data I am Software Developer. Use when data length is small or need to manipulate result before rendering to the output stream.

@Html.RenderPartial

@Html.RenderPartial returns void. Syntax : @{ Html.RenderPartial(“Partial View Name”); } Pass model with RenderPartial method Syntax : @{ Html.RenderPartial(“Partial View Name”, Model); } It is faster as compared to @Html.Partial because this result is written directly to the output stream. It’s result can not be manipulated. Use when data length is large or no need to manipulate result before rendering to the output stream.
