[jira] [Updated] (AVRO-823) Support Avro data files in C#

["Doug Cutting (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/AVRO-823?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Doug Cutting updated AVRO-823:
------------------------------

    Attachment: AVRO-823.patch

Before we can commit this we need it to build and pass tests.

The existing patch does not apply cleanly for me on Linux, failing on the .csproj files.  The new code also calls methods only in .NET 4.0, not in 3.5.  Here's a version that I think includes the right changes for the .csproj files in a patch that applies cleanly.  It also attempts to upgrade Avro.NET to .NET 4.0.  However a few tests still fail.  It would be best if someone who knows more about Mono were to get tests to pass on Linux and also to weigh in on whether we should upgrade to .NET 4.0 and if so whether I did this correctly.

Note also that I had to upgrade Newtonsoft.Json.dll to a .NET 4.0 version.

Failures I see are:

{noformat}Errors and Failures:
