I was just about to generate a client (proxy) for a WCF service on a computer (in a domain) on customer site when svcutil.exe returned the following:

Microsoft (R) Service Model Metadata Tool

HTTP GET Error
URI: http://127.0.0.1/CallahanWeb/service.svc?wsdl

The document was understood, but it could not be processed.
- The WSDL document contains links that could not be resolved.
- There was an error downloading 'http://dpc00000198.clients.eden/CallahanWeb/service.svc?wsdl=wsdl0'.
- The request failed with HTTP status 407: Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy service is denied. ).


If you would like more help, type "svcutil /?"

Seems that svcutil does not support http proxies that require authentication... After i disabled the proxy in IE's settings it worked

thinktecture and newtelligence AG present a week of Windows Communication Foundation (WCF), Windows Presentation Foundation (WPF) and Windows Workflow Foundation (WWF): TornadoCamp WinFX.

Christian, Ingo, Michael and me will present from the 16th - 20th of october in Bad Ems in GERMAN!

I posted some Bits Michael and I wrote recently in a WCF Project:

The Constraints-Extensions let you easily define attribute based limitations for input, output and return parameters. Limitations can be set to service contracts operations as well as to data contract data member implementations. The constraints validation gets called at runtime by the WCF infrastructure and the behavior will throw a ConstraintViolationException with descriptive messages in case of a constraint gets violated/the validation fails.

The following constraint attributes have been implemented:

• Between
• BetweenExclusive
• CompareAgainst
• EarlierThanNow
• EarlierThanToday
• EqualTo
• GreaterEqualTo
• GreaterThan
• LaterThanNow
• LaterThanToday
• LessEqualTo
• LessThan
• Match
• MaxElements
• MaxLength
• MinElements
• MinLength
• NotBetween
• NotEmpty
• NotEqualTo
• NotNull
• Nullable
• OneOff·    
  

Data Contract Sample:

[DataContract]
class TestClass
{
    [DataMember]
    [LessEqualTo(CompareAgainst.FieldOrProperty,"EndDate")]
    public DateTime StartDate;

    [DataMember]
    [GreaterEqualTo(CompareAgainst.FieldOrProperty, "StartDate")]
    public DateTime EndDate;

    public TestClass(DateTime startDate, DateTime endDate)
    {
        StartDate = startDate;
        EndDate = endDate;
    }
}

 

Service Contract Sample:

[ServiceContract, ConstraintsValidatorBehavior]
interface ITestConstraints
{

    [OperationContract]
    [return:GreaterEqualTo(0)]
    int MethodA(
        [Between(0,100)]
        int a,
        [LessEqualTo(20)]
        double b,
        [NotEmpty]
        string c); 

    [OperationContract]
    int MethodB(
        [Between(0, 100)]
        int a,
        [LessEqualTo(20)]
        ref double b,
        [NotEmpty]
        out string c);

    [OperationContract]
    [return:LaterThanNow]
    DateTime MethodC(
        [GreaterThan(0)]
        int a);

 

    [OperationContract]
    void MethodD(
        [VerifyObject]
        TestClass a);
}

I'm quite busy with a project I'm on with Clemens (the last before he'll join the Indigo team at Microsoft) - just to explain why it got bit quiet around me

Here is a modified version of the prop snippet that I want to share ( and remember :-P ).

Carefully said I do not like that sharepoint "hijacks" the Internet Information Server. When you create a virtual directory it is just not accessable because SharePoint took over IIS.

Funny fact: This is the second post how to fix issues with IIS and "extension" that cause issues

So i decided to hack a small utility serving my needs:

ExcludeFromSharepoint.zip (3.46 KB)

Enables to exclude applications from sharepoint services through the directory context menu.
Install using the "-install" switch; Uninstall using "-uninstall" switch.

Because I'm running my machine under a LUA (Limited User Account) i wrote the tool in a way that you can install and uninstall it without administative rights - the contextmenu will be installed per user!

if(args[0]=="-install")

{

    RegistryKey _rkey = Registry.CurrentUser;

    _rkey = _rkey.OpenSubKey("SOFTWARE\\Classes",true);

    _rkey = _rkey.CreateSubKey("Folder").CreateSubKey("shell");

    _rkey = _rkey.CreateSubKey("Exclude from Sharepoint");

    _rkey = _rkey.CreateSubKey("command");

    _rkey.SetValue(null, App.Application.ExecutablePath + " \"%1\"");

}

else if(args[0]=="-uninstall")

{

    RegistryKey _rkey = Registry.CurrentUser;

    _rkey = _rkey.OpenSubKey("SOFTWARE\\Classes\\Folder\\shell",true);

    _rkey.DeleteSubKeyTree("Exclude from Sharepoint");

}

else

{

...

}

 

The Implementation works with the webserver extensions version 4.0 or higher

 

    RegistryKey _rkey = Registry.LocalMachine;

    _rkey = _rkey.OpenSubKey("SOFTWARE\\Microsoft\\Shared Tools\\" +

        "Web Server Extensions",true);

   

    foreach(string _subKeyName in _rkey.GetSubKeyNames())

    {

        try

        {

            int.Parse(_subKeyName.Replace(".",""));

            RegistryKey _fpKey = _rkey.OpenSubKey(_subKeyName,true);

            _fpDir = (string)_fpKey.GetValue("Location");

        }

        catch(Exception _ex)

        {

            string _err = _ex.ToString();

            break;

        }

    }

 

and uses the stsadm.exe from the shared tools of the server extensions.

    System.Diagnostics.Process _p = new System.Diagnostics.Process();

    _p.StartInfo.FileName = Path.Combine(_fpDir, "BIN\\stsadm.exe");

    _p.StartInfo.Arguments = "-o addpath -url http://localhost/" +

        _strProjectName + " -type exclusion";

    ...

    _p.Start();

 

Like Christian Weyer and Damir Tomicic I like the word Indigo more than "WCF" and just read that Kenny will continue to refer to it as “Indigo” for a little while.
