docfx fails to find SQLitePCLRaw.core after upgrade

[roji]

On Ubuntu 18.04, mono 5.16.0.119 (preview), upgrading from docfx 2.32.2.0 to 2.39.1.0 and running docfx metadata gives:

Downloading https://www.nuget.org/packages/SQLitePCLRaw.core/ and manually copying the net45 version of SQLitePCLRaw.core.dll into the docfx dir seems to solve the problem.

I am also running into this issue on macOS, also with a preview version of Mono 5.16. The provided workaround also works. I suspect Mono is no longer shipping this assembly in its GAC and docfx should be bundling it.

| Component | Version |
|--|--|
| docfx | 2.38.1 |
| Mono | 5.16.0.163 |
| macOS | 10.14 Beta |

Workaround

nuget install -OutputDirectory $TMPDIR SQLitePCLRaw.core -ExcludeVersion
for docfx in /usr/local/Cellar/docfx/*; do cp "$TMPDIR/SQLitePCLRaw.core/lib/net45/SQLitePCLRaw.core.dll" "$docfx/libexec"; done

I am trying to fix this. However, I encountered #3746 when after copying SQLitePCLRaw.core.dll.

@pietervdvn I see you mentioned you make it work in #4043, could you share more details?

I am testing this with mono 5.18.0.225 to run docfx 2.40.10, with a Linux docker image running on Windows.

Once I copied in the .dll as mentioned in the first comment, it just worked fine for me.

I downloaded the package from nuget, and took the netstandard1.0 version, that worked for me.

@pietervdvn Thank you for your information. I can fix my error by adding another missing DLL.

2.40.12 fixed this.
