Converting null literal or possible null value to non-nullable type.

Dereference of a possibly null reference.

Nullability of reference types in return type of 'lambda expression' doesn't match the target delegate 'Func<JsonNode?, string?>' (possibly because of nullability attributes).

Converting null literal or possible null value to non-nullable type.

Dereference of a possibly null reference.

The type 'string?' cannot be used as type parameter 'TKey' in the generic type or method 'Enumerable.ToDictionary<TSource, TKey, TElement>(IEnumerable<TSource>, Func<TSource, TKey>, Func<TSource, TElement>)'. Nullability of type argument 'string?' doesn't match 'notnull' constraint.

Argument of type 'Dictionary<string, object?>' cannot be used for parameter 'queryParams' of type 'IDictionary<string, object>' in 'int RequestHelper.ParseContinuationParameters(JsonNode jresult, IDictionary<string, object> queryParams, IDictionary<string, string>? continuationParams)' due to differences in the nullability of reference types.

Argument of type 'Dictionary<string, object?>' cannot be used for parameter 'queryParams' of type 'IDictionary<string, object>' in 'int RequestHelper.ParseContinuationParameters(JsonNode jresult, IDictionary<string, object> queryParams, IDictionary<string, string>? continuationParams)' due to differences in the nullability of reference types.

Argument of type 'Dictionary<string, object?>' cannot be used for parameter 'queryParams' of type 'IDictionary<string, object>' in 'int RequestHelper.ParseContinuationParameters(JsonNode jresult, IDictionary<string, object> queryParams, IDictionary<string, string>? continuationParams)' due to differences in the nullability of reference types.

Possible null reference argument for parameter 'value' in 'PagesWithPropResultItem.PagesWithPropResultItem(WikiPageStub wikiPageStub, string value)'.

Converting null literal or possible null value to non-nullable type.

Non-nullable property 'Tags' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the property as nullable.

Possible null reference argument for parameter 'value' in 'JsonNode.explicit operator double(JsonNode value)'.

Dereference of a possibly null reference.

Dereference of a possibly null reference.

Argument of type 'List<string?>' cannot be used for parameter 'list' of type 'IList<string>' in 'ReadOnlyCollection<string>.ReadOnlyCollection(IList<string> list)' due to differences in the nullability of reference types.

Possible null reference argument for parameter 'expression' in 'DateTime MediaWikiHelper.ParseDateTime(string expression)'.

Possible null reference argument for parameter 'lagType' in 'ServerLagException.ServerLagException(string errorCode, string message, double lag, string lagType, string laggedHost)'.

Possible null reference argument for parameter 'message' in 'ServerLagException.ServerLagException(string errorCode, string message, double lag, string lagType, string laggedHost)'.
