I am playing with windows identity foundation and I am trying to create an MVC.NET based Security Token Service and use it as the Single Sign On application.
My only problem is that I don't know how to generate the federationmetadata.xml file.
Is there any tool to generate this file manually?
I created a custom metadata generator that does what VS does when you create the STS project. I had to use Reflection to call the code because as usual everything useful is internal in Microsoft's assemblies.
More about it here

This tool can be used modify an existing federationmetadata.xml
Load the VS2010 generated xml and change any attribute that you need to and save.
The saved version is compatible with the 2007-06 schema that VS2010 (WIF 3.5/ 4.0) use.
(would recommend backing up your original xml just in case )
I have done it many times and worked fine when I added STS reference to a Relying Party Website (VS2010 based)
Right click the project and configure STS.
