(405) Method Not Allowed. WCF WebService

Question

Introduction:

Hello, I am trying to set up a WCF web service on my local IIS 7.5 server, however after I finish the basic configurations I am unable to send data with a WinForms test client and it returns the error mentioned in the titles. I have already searched similar threads on this problem but i did not find anything that would fit my problem.

Data:

-Both the Wcf WebService and the test client where provided from a 3rd party

-They already work on another server and I am using the same versions

-I am probably doing something wrong when I enable or configure IIS

Request:

-I need to know what IIS features I need to enable/disable in order to install it correctly so I can use the Wcf WebService.(If that's the case).

-How to correctly configure the server in order to solve the above mentioned error.

My Configurations:

-After Installing IIS I changed the DefaulAppPool to .NET Framework v4.0.30.319; pipeline mode: Integrated. -Advanced Settings: Load User profile = False.

-Created a new Website named "WcfMicrocontrollerService" using DefaultAppPool.Binding; Type:http, IP adress: , port: 80

At this point I can access it trough a web browser, however when I use the test client to POST data to the service I get the following error: "The remote server returned an unexpected response:(405) Method Not Allowed."

Here are the data packets sent as recorded by Fiddler: Sent:

And here's the body: https://dl.dropboxusercontent.com/u/2237590/405.html

This seems to indicate that I should take a look in handler mappings but I have no idea what to edit there.

Ok so after a very brief search about your issue I found the following question WCF on IIS8; *.svc handler mapping doesn't work

Ignoring the fact that the question is about IIS 8, are you running Windows or Windows Server?

If you are using Windows go to...

• Control Panel -> Programs -> Programs and Features > Turn Windows Features on or off. Under the ".Net Framework 3.5 (Invlucdes .NET 2.0 and 3.0" section
• make sure that "Windows Communication Foundation HTTP Activation" is turned on.
• Also check under ".NET Framerwork 4.x Advanced Services" and under "WCF Services" check to ensure that HTTP Activation is turned on there as well.

This is a picture from that question showing the .net 4.5 change to make. Features to turn on

If you are using Windows Server try following the first answer to the question regarding how to set up the role using server manager.

I have managed to get the Web service working on another machine that had Windows 10(IIS 10) installed and your instructions where applicable. However under Windows 7 SP1 I have only the .Net Framework 3.5 option and I get the 500.21 error after I enable HTTP Activation but i am not stuck anymore and should be able to solve the problem on my own. I was looking in the wrong place and would of never figured this out. Thank you so much! – Putscher

I'm happy that this helped – Stogy

That really helped - worked fine under Server 2016 Preview 5 - I think that installed just about every feature by default. After a clean install of Server 2016 Standard this bit was driving me nuts and we all know how stressful that is when working to a schedule :-) – Landel

Installing HTTP activation fixed the 405 error I was getting after I had moved the WCF to a new web server with HTTP activation not installed. Thanks! – Podite

Thank you, sir! Adding HTTP Activation on Server 2016 was the fix for me too. – Icarus

this didn't work for me. I continue to get 500 errors 'cannot be activated due to an exception during compilation" see here #74380963 – Osugi
