Nullability of reference types in return type of 'Task<IReadOnlyList<T>?> DiscosClient.GetMultiple<T>(string queryString = "")' doesn't match implicitly implemented member 'Task<IReadOnlyList<T>> IDiscosClient.GetMultiple<T>(string queryString = "")'.

Nullability of return type doesn't match overridden member (possibly because of nullability attributes).

Argument of type 'Dictionary<string, string>' cannot be used for parameter 'initialData' of type 'IEnumerable<KeyValuePair<string, string?>>' in 'IConfigurationBuilder MemoryConfigurationBuilderExtensions.AddInMemoryCollection(IConfigurationBuilder configurationBuilder, IEnumerable<KeyValuePair<string, string?>>? initialData)' due to differences in the nullability of reference types.

Dereference of a possibly null reference.

Nullability of reference types in value of type 'List<string?>' doesn't match target type 'IEnumerable<string>'.

Non-nullable property 'States' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Non-nullable property 'DestinationOrbits' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Non-nullable property 'InitialOrbits' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Non-nullable property 'Operators' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.
