Nullability of reference types in type of parameter 'value' of 'bool ReadOnlyDictionaryWrapper<TKey, TValue>.TryGetValue(TKey key, out TValue value)' doesn't match implicitly implemented member 'bool IReadOnlyDictionary<TKey, TValue>.TryGetValue(TKey key, out TValue value)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'value' of 'bool ReadOnlyDictionaryWrapper<TKey, TValue>.TryGetValue(TKey key, out TValue value)' doesn't match implicitly implemented member 'bool IReadOnlyDictionary<TKey, TValue>.TryGetValue(TKey key, out TValue value)' (possibly because of nullability attributes).

Possible null reference argument for parameter 'controlUniqueId' in 'DotvvmControl? DotvvmControl.FindControlByUniqueId(string controlUniqueId)'.

Possible null reference argument for parameter 'value' in 'void HtmlWriter.WriteAttributeValue(string value)'.

Possible null reference argument for parameter 'text' in 'Literal.Literal(string text, bool renderSpan = false)'.

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 argument for parameter 'key' in 'bool IReadOnlyDictionary<string, IPropertyDescriptor>.TryGetValue(string key, out IPropertyDescriptor value)'.

The type 'DotVVM.Framework.Compilation.Javascript.Ast.JsExpression?' cannot be used as type parameter 'TNewNode' in the generic type or method 'JsAstHelpers.ReplaceWith<TNode, TNewNode>(TNode, Func<TNode, TNewNode>)'.
