Windows Identity Foundation 4.5 Configuration - wif

Question

We have an application that was originally built with .NET 4.0 and WIF 3.5 (1.0?). I'm in the process of converting it to use WIF 4.5 as we've upgraded the app to .NET 4.5. I've got all the code changes made and have been fighting with the configuration settings. My current dilemma is with the <claimTypeRequired> element. According to this documentation it should be a child of <identityConfiguration>, but when I modify my config to look like this
<system.identityModel>
<identityConfiguration>
<claimTypeRequired>
...
</claimTypeRequired>
I get the following error at run-time
Parser Error Message: Unrecognized element 'claimTypeRequired'.
If I just comment out the <claimTypeRequired> block I get past that error but then I'm presented with another problem. We had modified the maximumClockSkew in the existing application via the following configuration
<securityTokenHandlerConfiguration>
<maximumClockSkew value="1" />
</securityTokenHandlerConfiguration>
The configuration documentation referenced earlier doesn't even mention the maximumClockSkew. I figured I'd try leaving it in to see what happens. What happens is
Parser Error Message: Property 'maximumClockSkew' is not a ConfigurationElement.
But when I look at the SecurityTokenHandlerConfigurationElement class using JustDecompile I can see the property:
[ConfigurationProperty("maximumClockSkew", IsRequired=false, DefaultValue="00:05:00")]
[IdentityModelTimeSpanValidator(MinValueString="00:00:00")]
[TypeConverter(typeof(TimeSpanOrInfiniteConverter))]
public TimeSpan MaximumClockSkew...
So it seems like it's expecting it to be there.
It's almost like Microsoft doesn't actually want us to use this stuff.

Here's a decompilation of the IdentityConfigurationElement from resharper. You'll notice claimtyperequired is no longer a member of this element. It appears that claimTypeRequired is not part of the schema, despite the fact that it's in Microsoft's documentation.

By the way, if you haven't found out already about the claimTypeRequired attribute in the XML, you can use this as a workaround:
at the top of the config file, put this:
<section name="system.identityModel.services.serialization" type="System.IdentityModel.Services.Serialization , System.IdentityModel.Services, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
and then around the claimTypeRequired, here's an example:
<system.identityModel.services.serialization>
<claimTypeRequired>
<claimType type="http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name" optional="true"/>
<claimType type="http://schemas.microsoft.com/ws/2008/06/identity/claims/role" optional="true"/>
</claimTypeRequired>
</system.identityModel.services.serialization>
Kind regards,

Answer 3

you were almost close this is the answer for setting it in config
<securityTokenHandlerConfiguration saveBootstrapContext="true" maximumClockSkew="00:35:00" >
It works it sets it to value of 35 minutes here. hh:MM:ss
