It was implemented for use in cloudscribe SimpleContent, but could be used by anyone who would like to add Metaweblog API support to their web application.
Note the code in this repo is no longer used, the official code is now in the cloudscribe.SimpleContent repo
https://github.com/cloudscribe/cloudscribe.SimpleContent
MetaWeblog API is something you can use to create, edit, and publish content using desktop tools such as Open Live Writer. I specifically created this project in order to be able to use Open Live Writer with cloudscribe.SimpleContent, but I abstracted things so that others could use it too. Just implement and plugin your own implementation of IMetaWeblogService.
Note that this is not a generalized solution for XmlRpc, it is specifically an implementation of the MetaWeblog API
You can get it from nuget by adding this in your project.json dependencies
"cloudscribe.MetaWeblog": "3.0.*"
