Using VS2008, I noticed that in Class Project I only have a choice of adding "service reference" where as in Web Application project, I have two choices "web reference" and "service reference".
I have used web reference. How is "service reference" different from web ref? and what's the major purpose of service ref?
I'm helping out a colleague on this one so if I'm missing some details that's why.We have an asp.net 3.5 web application calling a WCF service. Originally the app used a "Web Reference" to register the service however after having some trouble and burning an incident with Microsoft their solution was to replace the "Web Reference" with a "Service Reference" to the WCF service.This is great except the problem is that when we create a Service Reference, the method signatures are different than they were when a Web Reference was used.From what I've read this may be expected, however in our case this would mean some significant changes to the application and of course it was due yesterday...so......I'm wondering two things:Is it normal/expected that method signatures will change based on the reference type?Is there a way to create the Service Reference that will generate method signatures identical to the original Web Reference?
View 1 RepliesI have built a WCF Service that is being consumed by a Silverlight app. At first I created one method that was very simple:
public String SfTest()
{
return "SF Test";
}
No poblem. My silverlight app references my service and displays "SF Test" in a textbox. Now I add a method to my wcf service like this:
public List<String> GetTest()
{
List<String> list = new List<string>();
String a = "a";
list.Add(a);
String b = "b";
list.Add(b);
return list;
}
I update the reference to the service in my Silverlight app and the using statement in my xaml cs page throws an error like the service doesn't even exist although it is there. I am assuming the problem has to do with datatypes or serialization or something like that but it is driving me up the wall. Why can't I consume a simple generic list in my Silverlight app through the WCF service.
I'm currently trying to work out the best way to build this web application, which will then be intergrated on other systems, such as WinForms, Intranets etc.
We hope to include the usual layers i.e. DAL, BLL, BOL and UI but I have been experimenting with Entity Framework 4 and WCF Data Services and managed to get something in place where I was using WCF as a gateway to EF4.
i.e. Adding a Service Reference to my project and then using the EF4 context and writing LINQ queries against the DB
e.g.[Code]....
Now with the current setup I would still need to write a DAL Class Library, that interacts with the Data Service, because as I said WCF Data Services only seems to be a gateway, I can't see where to put the code (above) in the Data Service and then how I could these methods.
My questions are: 1. How do I develop a WCF Data Service in such a way to allow this behaviour - I know how I could do it using ASMX web service, something like [Code]....
2. If I am to use WCF Data Services, how is serialization handled (if at all) - again I know how to do something in ASMX web services
3. Again, If I am to use WCF, how do I add Security and only allow my applications to access the web service - for obvious reasons
4. Would it be possible / logical to also include the Business Logic Layer into the web service?
How to create an instance of web service without adding web service reference? How to identify the server address/name where the web service is hosted from C# code?
View 1 Replies<Application architecture>I'm developing ASP.NET Web Application by Visual Studio 2008.(.Net Framework Version = 2.0)I put followin two projetcs in the solution.a. Class library which implements all the buisiness logic for application.
(I'll call it "ClassLib" in the followin sentence)b. ASP.NET Web applicatoin which presents UI.(I'll call it "WebApp")ClassLib uses Web Service which located on other server. So, I set web reference in it. Method for url settings for this web reference is "Dynamic".
How do I add the WCF service built using VS2010 as a service reference to a Winforms app which is written in VB6?
View 1 RepliesI am trying to call web reference "A" in an application.
The web reference "A" will then call a function in another web reference "B" through HTTPS connection (require certificate).
Then I keep getting the following error:
An unhandled exception of type 'System.Web.Services.Protocols.SoapException' occurred in System.Web.Services.dll
When you use ASP.NET web site (instead of web application model) and add reference to an assembly from local folder, Visual Studio, it seems, understands that this local assembly is also in GAC and so does NOT copy this assembly to bin folder (as it does with non-GAC assemblies), but simply adds new record in web.config file.
Why such a behaviour? Is it possible to force copy to bin folder (I need this since .dll is not on target environment)? I can add assembly to bin folder as file and it will work, but in this case bin folder contents will be in source control, which is not good.
I am working on converting a project from C# to VB and am facing this weird issue. 1 page cannot compile and I get the reference error, but the weird thing is that the compiler shows the error as coming from ASP.NET generated code. Visual Studio shows me that error is coming from my ASPX page. I cannot seem to figure out why or where this error is occuring. Also if I take the inherits attribute out I don't get the compilation error. The code in aspx page is below:

I am using VS2005, and a newbie at table adapters, DAL & BLL. I have a single dataset (in DAL) and 2 classes (in BLL) named Class1.vb and Class2.vb.
When I try to call a function from Class1 within Class2 I get the error "Reference to a non-shared member requires an object reference".
Here is a sketch of my code structure:
[Code]....
I have a Web service which, when updated on one computer with VS2008 works perfectly fine, but on another computer does not. The critical difference is the contents of the auto-generated Reference.cs.
In the correctly functioning environment, the methods have fully qualified class names, refering to classes in a class library. However, in the problem environment, the class names are unqualified and partial classes are declared near the end of the file. E.g.
[code]....
The code is under source control. Checking out to the working environment works straight away, checking out to the problem environment will only work if the reference.cs is manually edited to be like the working environments. Transferring the project manually from problem environment to the working one only requires an "Update Web Reference" to be performed to allow compilation. Both Reference.cs files claim to be auto-generated by the same tool version. The settings from the good environment have been exported to the other. No success so far...
I have a url like this:
http://www.somepage.com/main.aspx. In this page, when I click on a link it takes me to a page
http://www.somepage.com/cental.aspx?cid=200. So in the cental.aspx.cs page I did the following in the page load:
if(request.querystring["comp"].tostring() != null)
{
//do some thing [code].....
So I got an error like: object reference not set to an instance of reference.My problem is, I am using the same page. So when I go from some page, I will have "comp". but other times not. So when there is no "comp", how do I handle it in request.querystring?
I do not receive this error when I open my website application in vs 2005. When I open in vs 2008, I get this error. What gives?
These lines are underlined in blue:

I'm creating a DLL with a reference to web services (I don't have the choice to do so) but I have to add web service references to the project that uses the DLL for it to work. Example, I have the DLL called API.DLL that calls a web service called WebService.svc that I want to use in a project called WinForm. First, I have to add a "Service Reference" to WebService.svc in API.DLL. Then, I add a reference API.DLL to WinForm but it doesn't work unless I also add a service reference to WebService.svc in WinForm.
View 4 RepliesI am little bit confused in value type and ref. type memory allocation.
Consider following case:
public struct Employee
{
public int Emp_no;
public string Emp_name;
};
//Createing object of struct
Employee objEmp = new Employee;
objEmp.Emp_no = 1012;
objEmp.Emp_name = "emp name";
So I have query regarding :
Q1. 'struct' is a value type and 'string' is reference type of data type. Then if I use 'objEmp.Emp_name' is stored where? The location is in heap or in stack memory? What type of this 'Emp_name' variable?
Q2. If I run garbage collection explicitly then what will happen with 'objEmp' object?
I have my own web service application with more then one .asmx file. Now i am not getting how can i reference web service with my web application as "Add Web Reference".
I want to connect with both asmx files at once. Means once i connect web service as add web reference and i can call both .asmx file from my code behind page.
my user control i m calling the web service i added script manager in the web page how to add service reference in user control
View 2 RepliesI want to add web service reference but we are using proxy. Is there a way to bypass proxy and add web service reference?
View 1 RepliesWe inherited some code that makes use of a web service on an external server from a third party. Currently all the references are done in the project directly and thus compiled to that location and such. This issue we have is that there is a test and production server for the web service with different URLs.
Is there a simple means to make the web reference more dynamic so that it can be defined in a web.config and not require changing the actual source and recompiling to switch between servers?
I have a UI that communicates with a service. I made some changes to the service- added some code and a property in the Interface associated with the service. After I made the changes, I updated the service reference in my UI and I couldn't access my newly added property. I also tried deleting the reference and adding in back again, it still doesn't work. I get the following error:
xxxxxxx(filename) does not contain a definition for xxxx(propertyname) and no extension method accepting a first arguement of type xxxxx could be found(are you missing a using directive or an assembly reference?)
When I look in the Reference.cs file, I don't see the newly added property in it.
I have an ASP.net page that is creating a service reference to a WCF service and making calls in multiple places in my page. I instantiate the service reference in Page_Load and have an instance variable to store it:
private FooClient _serviceClient;
protected void Page_Load(object sender, EventArgs e)
{[code]...
I just discovered that I need to be disposing of the service reference when I am done using it or else the connections will be kept alive and will block incoming connections if I reach the max number of connections. Where would the best place to dispose of these references be? I was thinking of doing it on the OnUnLoad event.
I have a number of .Net web sites built in VS2010 using Framework 4.0that reference a web service to send emails.
My most recent site I created as a web application as opposed to a web site. In the Solution Explorer you can add a 'Service Reference' and, if you click the Advanced button you can then add a reference to a web service.
I did that and now the (web application) site won't build - it says it cannot load the Ajax dll. If I remove the reference to the web service, the site builds okay - if I add the reference back in, the site will not build.
Do I need to abandon the idea of using a 'Web Application' and turn it into a 'Web Site'?
I am getting an error when i try to add a service reference of a WCF service. Error details is below. My web service is hosted on a different server and my client is on different server. When i run the service directly from IE i can see the service but adding it in .net web application i get error.

I have web project and class projects. one of the Class project has web reference. and i am consuming it in web project.Question: can I change class projects web reference url depending on environment DEV, Release, Test?Question: While in runtime why does not web reference's url take value from app.config?(it is taking value from Settings.settings.)
