Preview: The SQLite Llibrary as a .NET assembly
The latest pre-release of SQLitePCLRaw contains a new bundle package called SQLitePCLRaw.bundle_cil. This package is like SQLitePCLRaw's other "bundle" packages except that it involves no P/Invoke and no platform-specific shared libraries. Instead, bundle_cil provides the SQLite library as a pure .NET assembly which was compiled by Llama.
Microsoft.Data.Sqlite 5.0 is available now on NuGet. Update today and let me know if you run into any issues.
