How to expose types generated by an F# Type Provider to C# and XAML -

so, i'm using xml type provider create types xml document.

one of elements in xml file has date property:

<edit date="06/30/2015 16:57:46"       ... /> 

which of course results in type this:

type edit =      inherit xmlelement      member date:  datetime     ... 

is there way can add following code:

 member this.localtime     get() =         this.date.tolocaltime() 

to resulting edit type?

the reason i'm binding instances of edit xaml , don't want write ivalueconverter that.

edit:

so, realized these types not make xaml. instead, instances of fsharp.data.runtime.basetypes.xmlelement of course not contain properties see in f# code. need consume these types c# code, , there xmlelements without properties

i know use xpath in xaml navigate xelements inside this, still need way access resulting object model in typed way, both c# , xaml.

edit2:

so wrote type extension this:

type catalog.edit     member this.localtime get() = this.date.tolocaltime() 

and see member in f# code generated members. there's 2 drawbacks approach:

1 - forced me change namespace module, less convenient since these types consumed c# code , in there see them nested classes module class, ugly.

2 - still can't see member (nor generated ones) either c# nor xaml.

what's correct way implement in described scenario?

the f# data type providers xml , json erasing type providers. means types see when use them f# not exist @ runtime - replaced underlying runtime representation (here xmlelement).

unfortunately, means types not real types , visible f#.

my recommendation define simple domain type using f# records , load data xml records. bit more work, gives bit more safety, because explicitly defining structure - , if xml changes, you'll know need change xaml code too!

it should easy this:

type edit = { date : datetime }  let getdata () =    let doc = myxmltype.load("somefile.xml")   seq { item in doc.edits -> { date = item.date } }
