+         so there will be an error if you reference certain types directly from this
+         project (e.g., StringReader). To fix this, the TFM here should be netstandard2.0,
+         but that is inconvenient during builds so for now it stays as this. The issue
+         will go away if a later MonoWASM BCL supports netcoreapp2.0 fully. -->
