In the csharp library, if there is an exception parsing a schema then we get a message with the exception details but no indication of where the error was in the schema's json.
I have updated the parser to catch these exceptions and rethrow a new exception with the JSON path to the error and the original exception. This requires an update of the NewtonSoft json.net package (current version is 3). Version 10.3 is about 2 years old and has the most downloads of any recent release. Suggest going to this one.
I if people agree this is a good idea I can put in a PR.
