I'm getting stumped by a very basic error.  I'm trying to add endpoints to a service through the `WCF Service Configuration Editor`, and it can't find the default output.  Here's every step I can take to reproduce the error.

**Add New WCF Service Application**

![New Project][1]

**Build Solution**

![Build][2]

**Edit WCF Configuration**

![Web.Config][3]

**Create New Service**

![New Service][4]

**Browse to Project Directory for Service Type**

![ServiceDll][5]

**Error Message**

![enter image description here][6]

This should work, but instead I get the following error message:

>Could not load file or assembly  
>'file://...\emptyservice\bin\EmptyService.dll'  
>or one of its dependencies.  
>Operation is not supported.  
>(Exception from HRESULT: 0x80131515)  


*What am I doing wrong?*

Microsoft Service Configuration Editor - Could Not Load File Or Assembly

Just to add the pure JavaScript answer, you can use [<code>JSON.Parse(string to parse)</code>][JSON.Parse] as well as [<code>jQuery.parseJSON(string to parse)</code>][parseJSON] without needing to load an entire framework. 



 var jsonData = "[{\"Name\":\"Name1\",\"Age\":20},{\"Name\":\"Name2\",\"Age\":23},{\"Name\":\"Name3\",\"Age\":28}]";
 
 var obj1 = JSON.parse(jsonData);
 var obj2 = jQuery.parseJSON(jsonData);

###[Here's a fiddle][fiddle]

[JSON.Parse]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse
[parseJSON]: http://api.jquery.com/jquery.parsejson/

When i serialize my DataTable using json.NET and return as json string in WCF service i have the following data

myJson data :

    [{\"Name\":\"Name1\",\"Age\":20},{\"Name\":\"Name2\",\"Age\":23},{\"Name\":\"Name3\",\"Age\":28}]

But it is not bind in jquery chart because of the escape characters. Actually when the above value is write in Console.WriteLine it returns the correct data like below. In Server side also if i use JsonTextReader data getting like below :

    [{"Name":"Name1","Age":20},{"Name":"Name2","Age":23},{"Name":"Name3","Age":28}]

So how to chnage the format in Jquery or can i send the data same as second one in wcf?

JSON Format Issue in JQuery

The WSDL is typically generated on the fly based on your models metadata, attributes, and host location. So if the wsdl is then proxied to another environment, it's going to have issues.

One escape hatch in [**`servicemetadata`**][5] is to specify a **`externalMetadataLocation`**:

> A Uri that contains the location of a WSDL file, which is returned to the user in response to WSDL and MEX requests instead of the auto-generated WSDL.

Add `externalMetadataLocation` like this below:



<pre><code>&lt;system.serviceModel&gt;
 &lt;behaviors&gt;
 &lt;serviceBehaviors&gt;
 &lt;behavior&gt;
 &lt;serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" 
 externalMetadataLocation="https://example.com/SOAP/Service1.wsdl" /&gt;
 &lt;/behavior&gt;
 &lt;/serviceBehaviors&gt;
 &lt;/behaviors&gt;
&lt;/system.serviceModel&gt;</code></pre>

You can then pre-generate your WSDL ahead of time, tweak at will, and upload the modified file to serve as the contract.

My apologize for long post...
We have a WCF service written in .Net 4.0 used internally within the organization. Recently there was a requirement to make this service available outside the organization network. So the network guys used reverse proxy to make this service available outside the organization. Here is the picture how it is set up.

![enter image description here][1]


As you can see in the picture..the service http://mywebservice.com/readd.svc is hosted on WIndows 2008 R2 which has a internal IP address as XXX.YYY.ZZZ.RRR. The service is hosted on port 80.

what is the problem ?.

Internally I can access the service as http://mywebservice.com/readd.svc using WCFTestClient and browser. But outside the organization if I type http://mywebservice.com/readd.svc I get "404 file not find error" and in WCFTestCleint I get error as "Error: Cannot obtain Metadata from http://mywebservice.com/readd.svc .........".

However if I type in the service as httpS://mywebservice.com/readd.svc in browser I get the screen which shows soap link as shown below. Please ignore the LookUpService.svc name mismatch.
![enter image description here][2]

As you can see in above figure ...address bar is https , but the soap link is http . If I click the http link http://.... ?wsdl , I get not found error. This is since Reverse proxy only allows connection as https .

If I use WCFTextClient and add servicie as https://mywebsite.com/readd.svc I get error as below.

"Error: Cannot obtain Metadata from https://mywebsite.com/readd.svc If this is a Windows (R)
 Communication Foundation service to which you have access, please check that you have
enabled metadata publishing at the specified address. For help enabling metadata publishing,

'The document format is not recognized (the content type is 'text/html; charset=UTF-8').'.- 
Report from 'http://mywebsite.com/readd.svc' is 
'The document format is not recognized (the content type is 'text/html; charset=UTF-8').'.-
 Report from 'DISCO Document' is 'There was an error downloading 'http://mywebsite.com/readd.svc?disco'.'. -
 The request failed with HTTP status 404: Not Found.- Report from 'WSDL Document' is 'The document format is not recognized (the content type is 'text/html; charset=UTF-8').'. "

I was informed by network guys to make service available as https. Here is my web.config file


 <system.serviceModel>
 <bindings>
 <basicHttpBinding>
 <binding name="BSBindingConfig" closeTimeout="00:10:00" openTimeout="00:10:00"

 <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
 </service>
 </services>
 
 
 
 </system.serviceModel>

Can you suggest how I can resole this issue ..so that users outside organization can access the api with WCFTestCleint as http/https .
