Hi Jaroslaw,

  1. I noted that the ability to specify case sensitivity was present in the deprecated "whenEquals" (etc) conditions, but not in the newer "when" condition. So I've added support for optional (defaulted) arguments for ConditionMethod methods, and given the standard string-related ones an optional ignoreCase argument.
  2. The users of our product need to see information in the Windows EventLog, but for certain information they don't want one message per log event - they want several log events combined into one Event Log entry, otherwise they get upset. This was not possible unless we combined information within our own application, as LogEventTarget does not support batched writes. So I've modified LogEventTarget to (optionally) support batched writes (see AllowBatching property). It now derives from TargetWithLayoutHeaderAndFooter, and has an AddNewLines property similar to the MailTarget. There's also a GroupByLevel property which allows a batch write to be gouped by EventLogEntryType and written as one EventLog entry per entry type - otherwise the greatest severity within the batch of LogEvents is used.

As a general note, I couldn't find any "how to contribute" documentation, so I'm not sure how you handle contributions, notably regarding copyright. For now, I've added copyright entries in the files I've touched/created with my name, but I'm open to discussion on this.

I've built the code via build.cmd for netfx40, netfx35, netfx20 and sl3 (that's all the SDKs I've got installed) and addressed any code analysis issues. I've tested under netfx40 (including my silverlight-only code). I've also verified that the generated XSD appears to be correct for the EventLogTarget changes, and syncronized projects.
