You could still open an archive in Update mode then call part.GetStream(FileMode.Create), in which case we'll want this call to SetLength, so we only avoid this call when the backing Archive is in Create mode. updating test to explicitly test the Update path for ZipPackage skip UAP since we don't have access to the file system to create the .zip undo accidental change to existing test removing unnecessary variable * Support custom converters that treat non-null input as null (#40287) (#40357)

Port #40287 to 3.0
cc: @eerhardt, @layomia, @ahsonkhan
Description
Adds support to allow a custom converter to return null on deserialize when the input is not null. This applies to both Nullable structs and also classes.
Without this, an
InvalidOperationExceptionis raised for the Nullable case and a Debug.Assert failure for the class case.There is not a valid workaround for this common so it will likely block usage of the serializer in these scenarios. The issue was requested by the community.
Regression?
No; the code is new in 3.0 (the custom converter code is < 2 months old).
Risk
Low. The code is very local to using
Nullable<T>and an additional check is made to see if there is a converter for the nullable type before asking for a converter for the underlying type.
