Answer 2

It seems to be quite a little known fact but .NET library includes packaging/compression API

Answer 3

There is a good article written by Peter Bromberg:

7Zip (LZMA) In-Memory Compression with C#

Shows a simple C# SevenZip.Compression.Lzma.SevenZipHelper class to enable high-compression of in-memory objects with C#. Adds a new 7Zip format LZMA Cookie Compression class to the previously published CookieCompression utility.

Answer 4

If you are writing individual files, then you could just treat it as a stream and use the inbuilt GZipStream / DeflateStream (although in some tests I did, #ZipLib out-performed the MS offering for both ratio and speed). Or there is inbuilt zip support somewhere in the framework. I don't know about LZMA, though.
