How to fix could not find a base address that matches schema http in WCF

Question

I m trying to deploy a WCF service to my server  hosted in IIS  Naturally it works on my machine     But when I deploy it  I get the following error       This collection already contains an   address with scheme http   There can   be at most one address per scheme in   this collection    Googling on this  I find that I have to put a serviceHostingEnvironment element into the web config file    lt serviceHostingEnvironment gt     lt baseAddressPrefixFilters gt       lt add prefix  http   mywebsiteurl   gt     lt  baseAddressPrefixFilters gt   lt  serviceHostingEnvironment gt    But once I have done this  I get the following      Could not find a base address that   matches scheme http for the endpoint   with binding BasicHttpBinding    Registered base address schemes are    https     It seems it doesn t know what the base address is  but how do I specify it  Here s the relevant section of my web config file    lt system serviceModel gt     lt serviceHostingEnvironment gt       lt baseAddressPrefixFilters gt         lt add prefix  http   mywebsiteurl   gt       lt  baseAddressPrefixFilters gt     lt  serviceHostingEnvironment gt      lt behaviors gt       lt serviceBehaviors gt         lt behavior name  WcfPortalBehavior  gt           lt serviceMetadata httpGetEnabled  true   gt           lt serviceDebug includeExceptionDetailInFaults  true   gt         lt  behavior gt       lt  serviceBehaviors gt     lt  behaviors gt     lt bindings gt       lt basicHttpBinding gt         lt binding name  BasicHttpBinding IWcfPortal                 maxBufferSize  2147483647  maxReceivedMessageSize  2147483647                 receiveTimeout  00 10 00  sendTimeout  00 10 00                 openTimeout  00 10 00  closeTimeout  00 10 00  gt           lt readerQuotas maxBytesPerRead  2147483647  maxArrayLength  2147483647                 maxStringContentLength  2147483647   gt         lt  binding gt       lt  basicHttpBinding gt     lt  bindings gt      lt services gt       lt service behaviorConfiguration  WcfPortalBehavior  name  Csla Server Hosts Silverlight WcfPortal  gt         lt endpoint address    binding  basicHttpBinding  contract  Csla Server Hosts Silverlight IWcfPortal        bindingConfiguration  BasicHttpBinding IWcfPortal  gt         lt  endpoint gt         lt endpoint address  mex  binding  mexHttpBinding  contract  IMetadataExchange   gt       lt  service gt     lt  services gt   lt  system serviceModel gt    Can anybody shed some light on what s going on and how to fix it

There should be a way to solve this pretty easily with external config sections and an extra deployment step that drops a deployment specific external  config file into a known location  We typically use this solution to handle the different server configurations for our different deployment environments  Staging  QA  production  etc  with our  dev box  being the default if no special copy occurs

If it is hosted in IIS  there is no need to specify a base address  it will be the address of the virtual directory

Only the first base address in the list will be taken over  coming from IIS    You can t have multiple base addresses per scheme prior to  NET4

Confirmed my fix   In your web config file you should configure it to look as such    lt system serviceModel  gt       lt serviceHostingEnvironment configSource    Configurations ServiceHosting config    gt            Then  build a folder structure that looks like this    web config  Configurations ServiceHosting config  Configurations Deploy ServiceHosting config   The base serviceHosting config should look like this    lt  xml version  1 0   gt   lt serviceHostingEnvironment aspNetCompatibilityEnabled  true  gt       lt baseAddressPrefixFilters gt       lt  baseAddressPrefixFilters gt   lt  serviceHostingEnvironment gt    while the one in  Deploy looks like this    lt serviceHostingEnvironment aspNetCompatibilityEnabled  true  gt       lt baseAddressPrefixFilters gt           lt add prefix  http   myappname web707 discountasp net   gt       lt  baseAddressPrefixFilters gt   lt  serviceHostingEnvironment gt    Beyond this  you need to add a manual or automated deployment step to copy the file from  Deploy overtop the one in  Configurations  This works incredibly well for service address and connection strings  and saves effort doing other workarounds   If you don t like this approach  which scales well to farms  but is weaker on single machine   you might consider adding a web config file a level up from the service deployment on the host s machine and put the serviceHostingEnvironment node there  It should cascade for you

I had to do two things to the IIS configuration of the site application   My issue had to do with getting net tcp working in an IIS Web Site App   First    Right click on the IIS App name   Manage Web Site  Advanced Settings Set Enabled protocols to be  http net tcp    Second    Under the Actions menu on the right side of the Manager  click Bindings     Click Add Change type to  net tcp  Set binding information to  open port number    OK

Try changing the security mode from  Transport  to  None           lt  -- Transport security mode requires IIS to have a            certificate configured for SSL  See readme for            more information on how to set this up  -- gt         lt security mode  None  gt

User · Answer

The solution is to define a custom binding inside your Web Config file and set the security mode to  Transport    Then you just need to use the bindingConfiguration property inside your endpoint definition to point to your custom binding     See here  Scott s Blog  WCF Bindings Needed For HTTPS

Any chance your IIS is configured to require SSL on connections to your site application

If you want to use baseAddressPrefixFilters in web config  you must setup IIS  6  too  This helped me   1  In IIS find your site  2  Properties   Web site  tab    IP address -  Advanced button 3  Add new host header on the same port which you will use in web config
