Cannot convert null literal to non-nullable reference type.

The type 'TKey' cannot be used as type parameter 'TKey' in the generic type or method 'ConcurrentDictionary<TKey, TValue>'. Nullability of type argument 'TKey' doesn't match 'notnull' constraint.

The type name 'triggers' only contains lower-cased ascii characters. Such names may become reserved for the language.

Nullability of reference types in type of 'event NotifyCollectionChangedEventHandler ObservableConcurrentDictionary<TKey, TValue>.CollectionChanged' doesn't match implicitly implemented member 'event NotifyCollectionChangedEventHandler? INotifyCollectionChanged.CollectionChanged'.

Nullability of reference types in type of 'event PropertyChangedEventHandler ObservableConcurrentDictionary<TKey, TValue>.PropertyChanged' doesn't match implicitly implemented member 'event PropertyChangedEventHandler? INotifyPropertyChanged.PropertyChanged'.

'ResultOverrideFilter.OnResultExecuted(ResultExecutedContext)' hides inherited member 'ResultFilterAttribute.OnResultExecuted(ResultExecutedContext)'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword.

'ResultOverrideFilter.OnResultExecuting(ResultExecutingContext)' hides inherited member 'ResultFilterAttribute.OnResultExecuting(ResultExecutingContext)'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword.

This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.

Possible null reference return.

Possible null reference argument for parameter 'hash' in 'Task<BlockHeader> BTCPayAppHub.GetBlockHeader(uint256 hash)'.

Possible null reference return.

Possible null reference argument for parameter 'value' in 'long Extensions.Value<long>(IEnumerable<JToken> value)'.

Possible null reference return.

Possible null reference argument for parameter 'value' in 'int Extensions.Value<int>(IEnumerable<JToken> value)'.
