Useful Tools
A number of useful tools were provided with NET 30
SvcTraceViewerSvcConfigEditor
New tools with NET 35Service Test HostService Test Client
6
Sample Test HostUseful Tools
NET 35 ships with simple generic hostWcfSvcHostexe
Must provide as command line argumentsService class assembly
Class library or application assembly Config file (may be separate from normal)Can optionally start a test client at the same time
7
Sample Test ClientUseful Tools
NET 35 ships with simple generic test clientWcfTestClientexe
Must provide service metadata as command line arguments
Eg WcfTestClient httpserverporturl
8
Useful Tools

9
Extra TipsUseful Tools
Can host within Visual Studio for F5rsquoing by using ldquoStart External Programrdquo
Can also have it call to the WcfTestClient
Can use with WCF 30 and Visual Studio 2005 if required ndash just add WcfSvcHost to the GAC
10
Unit Testing with Services
Testing Service Classes is no problemCreate class and invoke methods
Testing classes with dependencies on services is a problem
Should ideally remove dependenciesWhat if execution context matters
11
Hosting In-Process
Need a simple way to host a service in-process so we can simulate the WCF pipelineWant to support security transaction flow etcIdeally avoid any ldquoimplementationrdquo code
Proxy implementationConfig filesServiceHost wrapper
12
Hosting In-Process
demo
13
Per Operation Scope Extensions
Use an IDispatchMessageInspector to deal with ldquoper callrdquo concerns
Use an IServiceBehavior to apply the message inspector
I personally favour an attribute based approach
Add and reference your extensions from OperationContextCurrentExtensions
14
Tips for Data Contracts
General issues withWorking with OO mismatchesWorking with DataTables DataSetsDTO construction
Some useful advancements in 35 SP1Automatic support for graph serializationPOCO support for serialization
15
Operations Overloading Tips for Data Contracts
Cannot overload operations with services Can manually enable overloading
Use Name property to alias overloaded operations on service Generate proxy on client sideRename proxy methods to generate overloading Use Name property to alias overloaded methods on proxyMake calls on internal channel using the overloaded methods
16
Datasets and Tables Tips for Data Contracts
ADONET makes using DataSet and DataTable easy (too easy)Consider implications of passing dataset and data table
Inside layers of app probably fine Consider implications of publishing schema
Across technology boundaries consider returning arrays or other neutral representation

Fault Debugging
Two main desires for debuggingProviding detail of errors or exceptionsFlowing exceptions back to clients
Remember to use tracing informationExisting SDK tools help with this
SvcConfigEditorSvcTraceViewer
19
Providing Exception Details Fault Debugging
By default WCF will mask service exceptions Service exceptions returned as FaultExceptionThis is best practice (donrsquot leak)
However sometimes this is needed or usefulIncludeExceptionDetailInFaults property of ServiceBehavior attribute
Defaults to false Should only use in ldquodebugrdquo mode
20
Flowing Exceptions to the ClientFault Debugging
When debugging it is useful to flow exceptions
FaultExceptionltExceptionDetailgt class in the ServiceModel framework already caters for this

Extra TipsUseful Tools
Can host within Visual Studio for F5rsquoing by using ldquoStart External Programrdquo
Can also have it call to the WcfTestClient
Can use with WCF 30 and Visual Studio 2005 if required ndash just add WcfSvcHost to the GAC
10
Unit Testing with Services
Testing Service Classes is no problemCreate class and invoke methods
Testing classes with dependencies on services is a problem
Should ideally remove dependenciesWhat if execution context matters
11
Hosting In-Process
Need a simple way to host a service in-process so we can simulate the WCF pipelineWant to support security transaction flow etcIdeally avoid any ldquoimplementationrdquo code

12
Hosting In-Process
demo
13
Per Operation Scope Extensions
Use an IDispatchMessageInspector to deal with ldquoper callrdquo concerns
Use an IServiceBehavior to apply the message inspector
I personally favour an attribute based approach
Add and reference your extensions from OperationContextCurrentExtensions
14
Tips for Data Contracts
General issues withWorking with OO mismatchesWorking with DataTables DataSetsDTO construction
Some useful advancements in 35 SP1Automatic support for graph serializationPOCO support for serialization
15
Operations Overloading Tips for Data Contracts
Cannot overload operations with services Can manually enable overloading
Use Name property to alias overloaded operations on service Generate proxy on client sideRename proxy methods to generate overloading Use Name property to alias overloaded methods on proxyMake calls on internal channel using the overloaded methods

Datasets and Tables Tips for Data Contracts
ADONET makes using DataSet and DataTable easy (too easy)Consider implications of passing dataset and data table
Inside layers of app probably fine Consider implications of publishing schema
Across technology boundaries consider returning arrays or other neutral representation

Operations Overloading Tips for Data Contracts
Cannot overload operations with services Can manually enable overloading
Use Name property to alias overloaded operations on service Generate proxy on client sideRename proxy methods to generate overloading Use Name property to alias overloaded methods on proxyMake calls on internal channel using the overloaded methods
16
Datasets and Tables Tips for Data Contracts
ADONET makes using DataSet and DataTable easy (too easy)Consider implications of passing dataset and data table
Inside layers of app probably fine Consider implications of publishing schema
Across technology boundaries consider returning arrays or other neutral representation

Fault Debugging
Two main desires for debuggingProviding detail of errors or exceptionsFlowing exceptions back to clients
Remember to use tracing informationExisting SDK tools help with this

Providing Exception Details Fault Debugging
By default WCF will mask service exceptions Service exceptions returned as FaultExceptionThis is best practice (donrsquot leak)
However sometimes this is needed or usefulIncludeExceptionDetailInFaults property of ServiceBehavior attribute
Defaults to false Should only use in ldquodebugrdquo mode
20
Flowing Exceptions to the ClientFault Debugging
When debugging it is useful to flow exceptions
FaultExceptionltExceptionDetailgt class in the ServiceModel framework already caters for this
