These days friends and classmates say he encountered a problem when COM invoked the WCF service using service tokens, that is, the SOAP message he returned was greater than the default value of the Wshttpbinding of 65536, raising the call error. You need to change the maxreceivedmessagesize to a value that can hold large message content. The default wshttpbinding

The WCF deployment mode is flexible. You can select one of the most suitable hosts based on the service usage purpose.
Available host modes include:

By introducing the matching relationship between the WSDL element and the three elements of the endpoint through the implementation chapter, we know that the binding element of the WSDL originates from the binding object of the endpoint, so how are the binding metadata and the corresponding policy assertions written to the WSDL? The WSDL Export Extension (WSDL exports Extension) and the Policy export extension (Policy export Extension) are designed for this purpose.
First, WSDL Export extension
WCF Service (WebService)
Web Services is a proven cross-firewall communication method, which is stable and widely recognized. In general, you need to specify the corresponding interfaces for the scattered crud operations and faithfully call them in Silverlight.
Reasons for use: projects that require database interaction operations directly through services (weakening the business logic section ).
We introduced the service tag using the MEX contract to invoke the WCF service in COM in such a way that it is convenient to obtain metadata dynamically through the MEX endpoint, but sometimes the metadata of the service may contain sensitive information about the application that a malicious user can exploit.
