Type parameter 'T' has the same name as the type parameter from outer method 'ReadOnlyListExtensions.Join<T, TKey>(IReadOnlyList<T>?, IReadOnlyList<T>?, Func<T, TKey>, Func<T, T, T>)'

The type 'TKey' 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 'TKey' doesn't match 'notnull' constraint.

The type 'TKey' 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 'TKey' doesn't match 'notnull' constraint.

Parameter 'GeneratorAttributeSyntaxContext context' is captured into the state of the enclosing type and its value is also used to initialize a field, property, or event.

Type parameter 'T' has the same name as the type parameter from outer method 'ReadOnlyListExtensions.Join<T, TKey>(IReadOnlyList<T>?, IReadOnlyList<T>?, Func<T, TKey>, Func<T, T, T>)'

Possible null reference argument for parameter 'obj' in 'void PrinterContext.Append(object obj)'.

Nullability of reference types in return type of 'GraphQLRequest? GraphQLRequestFeature.Request.get' doesn't match implicitly implemented member 'GraphQLRequest IGraphQLRequestFeature.Request.get' (possibly because of nullability attributes).

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

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