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

Cannot convert null literal to non-nullable reference type.

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)'.

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)'.

Possible null reference argument for parameter 'item' in 'void List<object>.Add(object item)'.
