C# - How To Build URL Of WCF REST Web Services
Oct 26, 2010
I am using the new .NET 4 WCF REST web services. In order to link resources, I'd like to put links in my responses. In ASP.NET I can generate URLs from my routing configuration (e.g. UrlHelper.Action(...))
With WCF REST web services I have an ASP.NET routing configuration plus Uri templates:
[WebGet(UriTemplate = "{id}")]
MyResult Index(string id) {...}
I want to store related URIs in my result objects. How can I construct URLs from my routing configuration + UriTemplates without hardcoding base URLs or other information?

want to use Web Services in a project. I have basic concept of web services but couldn't understand some of its fundamentals.
1. what is SOAP, Rest and JSON ?
2. WCF Services are SOAP based or Rest or JSON based ?
3. Are Ado.net data services different from WCF ?
4. Which Web Services are easy to consume on client side ?

I want to develop my own REST service, so I've created an IHttpHandler that is configured with verb="*" and path="*", the the application in ~/MyRESTsrv/ will handle any derived URL.
This approach works good in IIS7 with "integrated mode" and apparently in IIS6 if you map all the extensions to "aspnet_isapi.dll".
Is this possible in Apache/XSP with Mono? Do I have to do something special or it will work out of the box?

I have looked at nearly every single WCF Rest PUT/POST issues on SO here and have still been unable to determine why I am unable to PUT or POST to my web service but am able to call a test GetTime method via GET. This particular service exchanges custom credential information (username, password and some other information) for a token. This token information is encrypted and added to the header of subsequent requests to other web services so that username/passwords don't have to be passed around everywhere. All web service calls are still treated as stateless, but require this auth header information rather username/passwords to access secured service operations.
[Code]....
I have also checked in IIS 7 the handler mappings for *.svc and checked that 'all verbs' are enabled.

I need to call a Rest service but would like to do so without having to redirect. Here is my dilemma. The Rest service we are trying to integrate offers the option to sign up for a subscription but does not allow us to upgrade an existing subscription. So if a user wants to upgrade an existing subscription we have to first cancel and then have the user sign up for a brand new subscription. I don't know how I can make this so it flows nicely in my code. I ideally I would like to do something like this
User decides to upgrade
Click upgrade button
Existing account is being cancelled, if cancellation was successful
New account is being created
How can I do this with a Rest service? Here is a sample URI/URL
https://someservice.com?
Action=CancelSubscriptionAndRefund
&AWSAccessKeyId=AKIAIIFXJCFIHITREP4Q
&CallerReference=CallerReference07
&CancelReason=MyWish
&RefundAmount.CurrencyCode=USD
&RefundAmount.Value=1
&SignatureMethod=HmacSHA256
&SignatureVersion=2
&Signature=1uFUSSFvau1zadnSzKRS5ZchuLMn9p5M3ifaHGHie7M%3D
&SubscriptionId=17d62772-c53e-4bdb-9667-65d7b7841cfc
&Timestamp=2009-10-06T08%3A05%3A13.296Z
&Version=2008-09-
Could anybody give me some ideas how to make this work in an elegant manner. We thought we could keep the old subscription and then just sign the user up for a new subscription for the difference of the money. For example the first subscription would be 2.95 and the second one would be 2.00 which would amount to a subscription of 4.95. I think it is not elegant and the user would see 2 charges on the credit card, weird, I think. Since I don't know much about Rest maybe there is a way that this can be solved.

If there is difference the can you provide me any link (which represents steps visually as in above link) through which I can develop rest web service ?

I have a question regarding a situation that occurs with GridView, ObjectDataSource in ASP .NET application. The GridView is linked to the ObjectDataSource and both are included within an UpdatePanel letting the GridView to fill in an asynchronous way from a form in the same page so it gets more rows as the user enters the data:
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="ObjectDataSource1">
<Columns>
<asp:BoundField DataField="Name" HeaderText="Name" ReadOnly="True"
SortExpression="Name" />
<asp:BoundField DataField="Periodicty" HeaderText="Periodicty" ReadOnly="True"
SortExpression="Periodicty" />
</Columns>
</asp:GridView>
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
SelectMethod="GetSessionNames" TypeName="Simulation"></asp:ObjectDataSource>
<asp:Label ID="Label27" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="NewWebSessionButton" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
I start the project with Visual Studio 2008, fill the form and it works correctly. Then I stop the execution: rerun again and the data I entered in the previous run is in the GridView. Is like some sort of cache saved the data from the session before. I checked that EnableCaching property is set to false for the ObjectDataSource. If I Rebuild Web Site in Visual Studio (not just Build) then it works corretly leaving the GridView empty. Is this caused just becuase of Visual Studio? Can it be turned off? And will it happen in the final IIS it will run on?

I am using Visual Studio 2010 Release candidate1. I have to deploy my web application which consists of a website, certain window services, certain WCF services and Sql Server 2005 database.I read Vishal Joshi's blog(http://vishaljoshi.blogspot.com/2009/09/overview-post-for-web-deployment-in-vs.html) detaing Web Package in VS2010. I want to know how to deploy window services and WCF services using Web Package. Also, I want to create a web setup (.msi) for deployment instead of Web Package so that the .msi takes care of all the application and database deployment like the web package does.

I have a large solution which has multiple apps which all share some common site elements (masterpages, navigation, etc).
Currently, all of these get built into a single DLL
If my structure looks like:
WebRoot
- Common/
- Shared/
- Images/
- App1/
- App2/
- etc
Is there a build tool which will allow me to build WebRoot.dll, App1.dll, App2.dll? I don't believe this is possible in VS2008 or the MSBuild tool.

I have a TFS build set up to deploy an ASP.net project to a test server.The build works great, and deploys to the test server fine, but instead of putting it into the Website directory that my IIS webserver is configured for, it puts the build into Website_20100511.6
Why is the date suffixed to the directory name? Is there a way to turn that off so I can publish directly to the Website?

I have been given some basic documentation of the RazorGator REST API and need to incorporate it into an ASP.NET 3.5 site. I've created my class file to call the API which contains my WebRequest.Create ("URL TO API"). How do I then make the output available so that it can be consumed by other pages? That is, the tickets.aspx page needs to obtain the output results of this API call. What constructs should I use to make this available in tickets.aspx?
Edit
Here's the code I've written thus far:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.IO;
using System.Net;
using System.Text;
namespace SeatEater.Web.UI.search
{
public class RazorGatorService
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://api.razorgator.com/ticketservice/ticets.xml?blahblah") as HttpWebRequest ;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream receiveStream = response.GetResponseStream();
StreamReader readStream = new StreamReader(receiveStream, encode);
response.close();
readStream.close();
}
}
I receive the error message:
A field initializer cannot reference the nonstatic field, method, or property 'field'
in the second line of the above codeblock. I'm very new to using HttpWebRequest and HttpWebResponse. Can you advise me as to how to rectify the error message I'm receiving?

Makes it sense to use ASP.NET applications together with WCF RIA Services or WCF Data Services (to encapsulate the data access layer) ? Or are these technolgies only useful for Silverlight applications.

tried so many different things but havent got past this seemingly trivial problem. I created a WCF service application from visual studio 2010 WCF templates. it generated the IService.cs and Service1.svc files and generated the web.config
i created a website in IIS 7 on windows 2008, and pointed it to the app folder. when i go to [URL] via web browser, i get a message indicating service is running and suggests using svcutil etc etc., but when i go to [URL] the web browser says 400 bad request. this is without changing anything from what VS generated. the operation contract looks like
[Code]....
Update: forgot to mention i even tried decorating the operation with WebGet attribute with UriTemplate parameter, without luck.

I'm considering to host WCF Rest Service that i've built on IIS 7. The URL to access my service will be something like
[URL]
Recently, i've been looking to some REST API implementation with a clean URL like Yahoo API
[URL]
I'm wondering what will be the best WCF host environment (e.g. Windows Service) or any solution (e.g. URL rewrite module) considering that I dont want to have application name and .svc in my URL so that I can have a completely clean URL for my REST API

I have three Divs on the page and they are absolute positioned. Lets call them leftDiv,middleDiv,rightDiv and middleDiv width is 900px which is okay but the left and right divs should fill the remaining the left and right parts respectively no matter what screen size is.
The reason why I use absolute positioning is because it is the only way to use height:100% to fill the page.
So how can I fill the remaining parts?
Of course these divs separate page into three pieces according to their names imply.
