IIS 7.5 WCF Error: Could not find a base address that matches…

Error

I received the following error while trying to run a WCF application built in Visual Studio 2013 running on a Windows 8 IIS 7.5 server.

Could not find a base address that matches scheme http for 
the endpoint with binding MetadataExchangeHttpBinding. 
Registered base address schemes are [https].

IIS Error

Solution

In this instance, my mex statement was wrong, I needed to make it mexHttpsBinding instead of mexHttpBinding. For other cases, double check that your bindings are correct. I was converting everything to HTTPS and had forgotten to change the mex binding to reflect the change.

<endpoint address="mex" binding="mexHttpsBinding" 
contract="IMetadataExchange" />

Solution

My problem was that WCF wasn’t enabled in the IIS server. To fix this, I ran the following commands in an administrator command prompt.

C:\> DISM /Online /Enable-Feature /FeatureName:WCF-HTTP-Activation
C:\> DISM /Online /Enable-Feature /FeatureName:WCF-HTTP-Activation45
