Use collection expressions? Other than that, looks good.

I'll poke around a bit to see if I can manage to get a regression test for this without using the customer file but for now just sharing the fix.
Yes that would be great.
Otherwise, this LGTM.

Corrected some mismatched active issues, filed a new active issue for a test crash in linq.expressions. With that BA is passing. |

Fix #100198.
This Windows API will still try to write to a buffer if you tell it the buffer is 0 length and the string you're reading happens to be 0 length. We previously avoided an AV here because we were passing a StringBuilder, but that changed with the interop generator refactoring which passed
null. Avoid the bug that by passing in a 1-character buffer rather than null.I've tested manually using the file provided in the issue repro. I'll poke around a bit to see if I can manage to get a regression test for this without using the customer file but for now just sharing the fix.
