C# - How To Configure Endpoint For Web Service Declared With WebService() Attribute

Oct 13, 2010

We have a C# Web Service that declares itself using attributes. The code-behind file looks like:

[WebService(Namespace = "http://the.web.service.url/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public sealed class TheWebservice : WebService
{
[WebMethod]
public SomeObject TheFunction()
...

The web services has worked for a long time now. Recently, one request resulted in an error:

The maximum string content length quota (8192) has been exceeded while reading XML data. After searching around, I found that there is a setting maxStringContentLength that can increase the meaximum size. The post says you can configure this setting in Web.config in the BasicHttpBinding section. You can then specify that BasicHttpBinding in an endpoint section. But since we declare the webservice using the WebService attribute in the code-behind file, we do not have an endpoint section.

Is there a way to specify an endpoint using a declarative attribute? Alternatively, is it possible to switch from attribute to web.config mode without breaking existing clients? Am I confusing WCF and its predecessor here?

C# - Why Is System.Data.Services.MimeTypeAttribute Now Only A Class Level Attribute

Apr 7, 2010

I'm getting started with Astoria/ADO.NET Data Services/WCF Data Services. Looking through a lot of the code samples out there, it appears that the MimeType attribute used to be a method level attribute. After installing the latest update, it is now a class level attribute.

If I have more than one Service Operation that I want to return as a certain MimeType, then it appears now that I have to create a new service for each operation. Is this correct?

Most examples are like this:

[WebGet]
[SingleResult]
[MimeType("application/pdf")]
public IQueryable<byte[]> FooPDF()
{
var result = from p in this.CurrentDataSource.MyPDFs
where p.FooID == 2
select p;
return result.Take(1).Select(p => p.PDF);
}

I get "Attribute 'MimeType' is not valid on this declaration type. It is only valid on 'class' declarations." when I compile, because now I can't do this.

Now, I have to do this:

[MimeType("FooPDF", "application/pdf")]
public class FooService : DataService<FooDBEntities>
{
public static void InitializeService(DataServiceConfiguration config)
{
config.SetServiceOperationAccessRule("FooPDF", ServiceOperationRights.All);
}
[WebGet]
[SingleResult]
public IQueryable<byte[]> FooPDF()
{
var result = from p in this.CurrentDataSource.MyPDFs
where p.FooID == 2
select p;
return result.Take(1).Select(p => p.PDF);
}
}

What's worse is that I can't add duplicate MimeType attributes to my class.

C# - System.ServiceModel.CommunicationException On Overloading Webservice?

Jun 15, 2010

I am load testing my webservice

and get a
System.ServiceModel.CommunicationException

when I use 10 threads to communicate to it (without any sleep in between) - basically testing 10 conenctions at a time - through a windows application

An error occurred while receiving the HTTP response to http://localhost/XXX/XXXService.asmx. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.Why would this happen and how to best resolve it Also is this the way how asp.net application will interact with it too - is threading the best way to do the load testing

MVC Generic Base View Class / Error Parsing Attribute 'something': Type 'System.Web.Mvc.ViewPage'

Feb 5, 2010

I can have a base class for views in an MVC project like this:

public class BaseViewPage : System.Web.Mvc.ViewPage
{
public string Something { get; set; }
}

And then in the ASPX I can do this:

<%@ Page Something="foo" Language="C#" Inherits="MyNamespace.BaseViewPage" %>

This works fine; the problem is when I try to do the same with the generic version:

public class BaseViewPage<TModel> : System.Web.Mvc.ViewPage<TModel> where TModel : class
{
public string Something { get; set; }
}

When I try to use this from the ASPX, like this:

<%@ Page Something="foo" Language="C#" Inherits="MyNamespace.BaseViewPage<SomeClass>" %>

I get the error message:

Error parsing attribute 'something': Type 'System.Web.Mvc.ViewPage' does not have a public property named 'something'.

Notice how it tries to use System.Web.Mvc.ViewPage rather than my BaseViewPage class. To make it more interesting, if I remove the "Something" attribute from the Page directive and put some code in the generic version of BaseViewPage (OnInit for example) the class is actually called / used / instantiated.

So, am I doing something wrong or is this a limitation.

C# - Retrieve The Name Of The Attribute Dynamically Without Specifying The Name Of The Attribute?

Aug 13, 2010

I am developing asp.net mobile application. I am using LINQ to XML to query XML file. I am using the following query to retrieve the name & value of the query dynamically as follows

var TotalManifolds = from MF in FieldRoot.Element("FIELD-DEFINITION").Element("MANIFOLDS").Elements("MANIFOLD")
join SLT in FieldRoot.Element("FIELD-DEFINITION").Element("SLOTS").Elements("SLOT")
on (string)MF.Attribute("MID") equals (string)SLT.Attribute("PARENT")
select new
{
SlotName = (string)SLT.Attribute("NAME").Value,
SlotValue = (string)SLT.Attribute("NAME").Value
};

In the following statement of above query I want to retrive the name of the attribure dynamically without explicitly specifying the name of the attribute SlotName = (string)SLT.Attribute("NAME").Value Here I am explicitly specifying the name. I want to code which can dynamically retrieve the name of the attribute. I am new to Linq to xml. how this can be done programatically? or can you provide me the link through which I can resolve the above issue ?

Error CS0029: Cannot Implicitly Convert Type Media.WebService.multiValuedAttribute To Media.WebService.multiValuedAttribute[]

Aug 5, 2010

In Visual Studio 2008 I have a Class Library project (called Media) to which I added a Web Reference (not a Service Reference) to a third-party web service (wsdl). In the Class Library project a proxy class is created for using the service along with several classes for the types used in that service.

I also have a second Class Library (called Sync) that references the first one. And then I have a Web Site project that references the second class library. All of this is .NET 3.5

So Web Site > Class Library (Sync) > Class Library with web service reference (Media)

I want to step into the generated code, so I fire up the web site in IIS 7.5 and trigger the call to a method in the second class library (Sync) that in turn should call the web service proxy. I was fully expecting to hit the breakpoint, but instead got an exception:

Unable to generate a temporary class(result=1). error CS0029: Cannotimplicitly convert type Media.WebService.multiValuedAttribute to Media.WebService.multiValuedAttribute[]

Why is ASP.NET trying to generate a temporary class? Don't I already have the generated class from the first Class Library (Media)?
