CONTRACT FIRST UTILITY
WCF 4.5 give us the capability to build data
contracts and classes directly from XSDs.
To use the contract-first tool, the XSD must be
downloaded locally.
The contract-first tool is integrated into Visual
Studio 2012 as a build task.
You can configure how the dev environment will
create the contracts through the “WCF Options”
item in the Project properties.

P:6
Serializer Mode: This setting determines which serializer is used for reading service contract files
Reuse Types: This setting specifies which libraries are used for type reuse.
Collection Type: This setting specifies the fully-qualified or assembly-qualified type to be used for the
collection data type.
Dictionary Type: This setting specifies the fully-qualified or assembly-qualified type to be used for the
dictionary data type.
EnableDataBinding: This setting specifies whether to implement the INotifyPropertyChanged interface
on all data types to implement data binding.
ExcludedTypes:This setting specifies the list of fully-qualified or assembly-qualified types to be excluded
from the referenced assemblies.
GenerateInternalTypes: This setting specifies whether to generate classes that are marked as internal.
GenerateSerializableTypes: This setting specifies whether to generate classes with the
SerializableAttribute attribute.
ImportXMLTypes: This setting specifies whether to configure the data contract serializer to apply the
SerializableAttribute attribute to classes without the DataContractAttribute attribute
SupportFx35TypedDataSets: This setting specifies whether to provide additional functionality for typed
data sets created for .Net Framework 3.5..
InputXsdFiles: This setting specifies the list of input files.
Language: This setting specifies the language of the generated contract code.
NamespaceMappings: This setting specifies the mappings from the XSD Target Namespaces to CLR
namespaces.
OutputDirectory: This setting specifies the directory where the code files will be generated.
BETTER INTEGRATION WITH THE HOST
• Automatically inherit the security settings for IIS
• Inherit SSL settings
• Inherit authentication modes (and will also support
multiple authentication modes per end point )
**** previously if you wanted to configure a WCF endpoint that
supported a variety of the transport security modes, those
were each separate end points and there was one per end
point and they would often sit at different addresses - 4.5 will
support multiple authentication modes.

INTELLISENSE – TOOL TIPS
With Intellisense you get context help (Tooltip
Text) that helps to define a particular selection
P:8
INTELLISENSE – TYPES OF
When configuring an <endpoint> you can now
reference a dropdown for the contract
(Intellisense lists all contracts in your project)
P:9
INTELLISENSE – TYPES OF
When configuring custom bindings – say wiring
up a binding reference type in the definition of
your <endpoint> - Intellisense is smart enough to
reference those which are (already) defined
within your config file…

CLEAN CLIENT CONFIGURATION GENERATION

CLASSES FROM XML
You can generate a class from a sample XML
document using the “Paste XML as classes”
feature of Visual Studio.
This is a .NET 4.5 feature (not specific to WCF)
