Samples on the docs.ms samples browser

[cartermp]

I noticed that the 101 LINQ samples aren't on the samples site: https://docs.microsoft.com/samples/browse/?term=linq

Are there other missing?

@cartermp I ported all these to the try-samples repo, using the local try.net experience.

I do need to point these to the new browser.
