Via Postman I am receiving the the following response:
The WebHook request must contain an entity body formatted as JSON
With the help of some online tutorials I set up a webhook receiver that successfully reads in events from GitHub.
The next hurdle is being able to to receive a request containing XML data. I brought in the relevant WebHooks.Custom packages via NuGet so that I can handle a less specific request. I'm able to get into the ExecuteAsync method in my CustomWebHookHandler class and read in the data if it's sent as JSON, but if I change the raw body of the request to XML (along with the content-type in the header) I get the error listed above.
Do .NET Web API projects not handle XML out of the box? All commments I found elsewhere stated that they do handle XML.
If they don't handle XML out of the box how do I change the app to allow XML?
If they do handle XML out of the box why am I getting the error message above?

I am using Stripe.net SDK from NuGet. I always get the exception from StripeEventUtility.ConstructEvent method.
The WebHook key is correct, the Request Header contains "Stripe-Signature" keys.
I correctly receive incoming data from the Webhook tester utility (using nGrok with Visual Studio).
I tried to manipulate the incoming data from Stripe (Jobject, string, serializing...). The payload signature may cause some problem.
Has anybody had the same problem?

Are you referring to the Stripe CLI, using the listen command and forwarding to your endpoint? If so, it's important that you use the webhook secret returned by the listen command, and not one related to a configured endpoint on your Dashboard.
The other main source of this issue is mutation of the request body. Signature verification depends strictly on having access to the raw body of the request, including original whitespace etc.
See this sample implementation of a webhook endpoint in .NET accessing the raw request body: https://github.com/stripe-samples/accept-a-payment/blob/main/custom-payment-flow/server/dotnet/Controllers/PaymentsController.cs#L86
The SOAP service I am consuming will send back a 202 Accepted. All I want to do is capture this 202 so I can confirm that the server received the message.
I have found this:

So the answer states to implement a soapextension and links to msdn. I looked at the sample code, and I am having a hard time understanding what I should do. The client that was generated submits the data in the following way:
psrs.SubmitPersonSearchRequest(psrt);
and has a void return. How do I get the response from the server?
I was able to see the correct response in soapui and in fiddler.
I'm writing a .Net 3.5 solution which is consuming a 3rd party WCF web service. The proxy client for the SOAP service was generated by VisualStudio as a service reference.
A SOAP response from the service includes attachments in the data, as I can see it in fiddler. The attachments have a href field which points to a CID reference. The proxy client that VS 2012 has created when returning the object which includes the attachments doesn't include any binary data, but it does include the href field with the CID reference in it.
As captured using fiddler, this is the SOAP response attachment data including the cid:xxxx ref:
<attachments>
<cmn:attachment href="cid:52b2d8a50035921e80bf1540" len="309" name="DOC1.rtf" type="application/rtf" xmime:contentType="application/rtf"/>
</attachments>
And in the raw output in fiddler, the attachment data can be seen with the matching cid:xxxx ref:
------=_Part_22_12445037.1389617382038
Content-Type: application/rtf
Content-Location: DOC1.rtf
Content-ID: <52b2d8a50035921e80bf1540>
Content-Transfer-Encoding: binary

Here is a screenshot of the available fields from the returned object:
How do I access that attachment data so I can actually download the file?
Normally with WCF and SOAP, your file binary is encoded as a base64 string somewhere in your response, however I don't see in what you've posted here the kind of long data string I'd be expecting.
If what you're showing here is just the header from the response, you might check the body of the response message,too, since the header has a size limit, but the body the message doesn't - it's therefore the likely place for your binary payload.
Wouldn't it be easier to return a byte[] in one of the entities you are returning, and then work from that on your client to reconstruct the file?
Are you using MTOM? Because WCF does not support SwA (Soap with attachments) out of the box.
Turns out that the issue was due to the way the 3rd party API was returning the response, the MTOM data was not correctly formatted so WCF was ignoring the binary data.
The way I got around this was by using a bespoke class which basically uses an HttpRequest to talk directly to the web service and extract/parse the binary data out of the response.
I'd like to sign a Soap request (.NET 3.5, C#) with a certificate stored in the computer (reading of certificate is ok).
I don't want the request to be encrypted (that's what I get when I change Security.Mode and Security.Message properties on WSHttpBinding). I am looking for a signed Soap header.
After reading tons of articles on MSDN, blog, StackOverflow... I came up with this approach: using IClientMessageInspector and method BeforeSendRequest. I can set a breakpoint in it and see my request, but how to modify its XML content?
Modifying the message is possible - for sample code and explanations see

Basically you copy the Message to an XML Doc as a buffered copy, modify the XML, then create a new Message from that modified XML and assign the new Message to the ref Message param...
I've built a simple C# app (.Net 4.0 + WPF) which can send and receive JSON messages via TCP sockets.
As a next step, it should be possible that JavaScript apps on websites and PHP scripts can send and receive JSON messages to/from my app. Is that possible?
Since JS/PHP will use stateless HTTP connections, how should a request to my app work, for example, should the JS/PHP apps send a JSON message to my app and my app response (HTTP response) with a JSON message? Is that even possible? And should I use GET or POST method to send the JSON messages to/from my app?
Hope my questions do not cause too much confusion ;-) I but I appreciate every tip, clarification or feedback you can give me.

You can accomplish this via a .NET web service using special JSON directives on the web method, e.g.
[ScriptMethod(UseHttpGet = true, ResponseFormat=ResponseFormat.Json)]
public string DoSomething(string param1, int param2)
{
// Do Something
}
When the ResponseFormat.Json property is specified, the data returned will be serialized into the appropriate JSON format. Also note, in order to recieve a true JSON response, you'll need to set your content-type to "application/json" from the requesting application. Otherwise, the method will attempt to wrap the response in XML.
Also, I am enabling a HttpGet on this method so that you can post via a query string to the method, e.g.
http://www.example.com/service.asmx?param1='Hello'¶m2=1;
