Introduced with C# 8.0, we can annotate the code to specify if a reference-type variable can be null or not. Then, we can enable a new static analysis check that check for potential code paths that will de-reference a null pointer, throwing a NullReferenceException.
Annotating the API allows user to enable the feature as well and ensure a safe usage of the code. Fix all the related warnings
This is introducing the following breaking changes:
TextDataReader will not return null string if it starts reading from the end already. It will throw EndOfStreamException.
Po initializes an empty header.
Properties of PoHeader are initialized to an empty string instead of null values, CreationDate is set to current time.
The setter of Po.Header will not check if the header has some required non-empty properties.
Po2Binary will write the PO header only if ProjectIdVersion is non-empty instead of checking if the Header property is null.
Example
To enable the feature in any user project, just set <Nullable>enable</Nullable> in the csproj.
