Nullability of reference types in return type of 'IPipelineWriter? ResourceCacheDiscoveryContext.Writer.get' doesn't match implicitly implemented member 'IPipelineWriter IResourceDiscoveryContext.Writer.get' (possibly because of nullability attributes).

Possible null reference argument for parameter 'moduleName' in 'void RunspaceContext.VerboseFoundResource(string name, string moduleName, string scriptName)'.

Possible null reference argument for parameter 'name' in 'bool ILanguageScopeSet.TryScope(string name, out ILanguageScope? scope)'.

Possible null reference argument for parameter 'file' in 'SourceExtent.SourceExtent(ISourceFile file, int? line, int? position)'.

The type 'YamlDotNet.Core.Events.Scalar?' cannot be used as type parameter 'T' in the generic type or method 'ParserExtensions.TryConsume<T>(IParser, out T)'. Nullability of type argument 'YamlDotNet.Core.Events.Scalar?' doesn't match constraint type 'YamlDotNet.Core.Events.ParsingEvent'.

The type 'YamlDotNet.Core.Events.Scalar?' cannot be used as type parameter 'T' in the generic type or method 'ParserExtensions.TryConsume<T>(IParser, out T)'. Nullability of type argument 'YamlDotNet.Core.Events.Scalar?' doesn't match constraint type 'YamlDotNet.Core.Events.ParsingEvent'.

Possible null reference argument for parameter 'file' in 'bool JsonReaderExtensions.GetSourceExtent(JsonReader reader, ISourceFile file, out ISourceExtent? extent)'.

Possible null reference argument for parameter 'extent' in 'bool ResourceObjectJsonConverter.TrySpec(JsonReader reader, JsonSerializer serializer, string propertyName, string apiVersion, string kind, ResourceMetadata? metadata, CommentMetadata? comment, ISourceExtent extent, out IResource? spec)'.
