One option could be to use Audit.DynamicProxy to intercept the proxy calls, so for example if you use the ChannelFactory to create the proxy, you could do the following:
using Audit.DynamicProxy;
public T CreateProxy<T>(Uri uri, HttpBindingBase binding)
{
var channelFactory = new ChannelFactory<T>(binding, new EndpointAddress(uri));
return AuditProxy.Create<T>(channelFactory.CreateChannel());
}
Then when you do a service call, for example:
var proxy = CreateProxy<ICatalogService>(uri, binding);
var product = proxy.GetDetailedProductInfo(new GetDetailedProductInfoRequest() { ProductId = "1234" };
You should get an audit event with format similar to:
{
"EventType": "generatedProxy_1.GetDetailedProductInfo",
"Environment": {
...
},
"StartDate": "2021-07-16T19:48:15.294298Z",
"EndDate": "2021-07-16T19:48:21.6566853Z",
"Duration": 6362,
"InterceptEvent": {
"ClassName": "generatedProxy_1",
"MethodName": "GetDetailedProductInfo",
"IsAsync": false,
"InstanceQualifiedName": "generatedProxy_1, ProxyBuilder, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null",
"MethodSignature": "CatalogService.GetDetailedProductInfoResponse GetDetailedProductInfo(CatalogService.GetDetailedProductInfoRequest)",
"Arguments": [
{
"Index": 0,
"Type": "GetDetailedProductInfoRequest",
"Value": {
"request": {
"ProductId": "1234"
}
}
}
],
"Success": true,
"Result": {
"Type": "GetDetailedProductInfoResponse",
"Value": {
"GetDetailedProductInfoResult": {
"Product": {
"ProductId": "1234",
"Description": "Some description".
"CreationDate": "2007-10-31T11:30:35-06:00"
}
}
}
}
}
}

You can now use the extension library Audit.WCF.Client which allows auditing client-side WCF service calls.
Please check the documentation here.
It's basically an IClientMessageInspector that intercepts the request and response messages.
