'LoadingBarExtension.AddLoadingBar(IServiceCollection, Action<LoadingBarOptions>?)' is obsolete: 'Use "services.AddLoadingBarService();" instead.'

Nullability of reference types in type of parameter 'arg' of 'bool? StringToBoolConverter.OnSet(string arg)' doesn't match the target delegate 'Func<string?, bool?>' (possibly because of nullability attributes).

Possible null reference return.

Argument of type 'StringToBoolConverter' cannot be used for parameter '__arg2' of type 'Converter<string, bool?>' in 'void TypeInference.CreateMudCheckBox_5<string>(RenderTreeBuilder __builder, int seq, int __seq0, string __arg0, int __seq1, Color __arg1, int __seq2, Converter<string, bool?> __arg2, int __seq3, bool __arg3, int __seq4, string __arg4, int __seq5, EventCallback<string> __arg5)' due to differences in the nullability of reference types.

Argument of type 'StringToBoolConverter' cannot be used for parameter '__arg2' of type 'Converter<string, bool?>' in 'void TypeInference.CreateMudCheckBox_6<string>(RenderTreeBuilder __builder, int seq, int __seq0, string __arg0, int __seq1, Color __arg1, int __seq2, Converter<string, bool?> __arg2, int __seq3, bool __arg3, int __seq4, string __arg4, int __seq5, EventCallback<string> __arg5)' due to differences in the nullability of reference types.

Possible null reference assignment.
