Nullability of reference types in type of parameter 'name' of 'ValidateOptionsResult OptionsValidator.Validate(string name, ShimDurableTaskClientOptions options)' doesn't match implicitly implemented member 'ValidateOptionsResult IValidateOptions<ShimDurableTaskClientOptions>.Validate(string? name, ShimDurableTaskClientOptions options)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'name' of 'void OptionsConfigure.PostConfigure(string name, ShimDurableTaskClientOptions options)' doesn't match implicitly implemented member 'void IPostConfigureOptions<ShimDurableTaskClientOptions>.PostConfigure(string? name, ShimDurableTaskClientOptions options)' (possibly because of nullability attributes).

Prefer the generic overload 'Microsoft.DurableTask.Client.DurableTaskBuilderExtensions.UseBuildTarget<TTarget>(Microsoft.DurableTask.Client.IDurableTaskClientBuilder)' instead of 'Microsoft.DurableTask.Client.DurableTaskBuilderExtensions.UseBuildTarget(Microsoft.DurableTask.Client.IDurableTaskClientBuilder, System.Type)' (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca2263)

Elements should be documented (https://github.com/DotNetAnalyzers/StyleCopAnalyzers/blob/master/documentation/SA1600.md)

Missing XML comment for publicly visible type or member 'StartOrchestrationOptionsExtensions.ValidDedupeStatuses'

'OrchestrationRuntimeStatus.Canceled' is obsolete: 'The Canceled status is not currently used and exists only for compatibility reasons.'

Possible null reference return.

The type 'TState' cannot be used as type parameter 'TState' in the generic type or method 'ILogger.BeginScope<TState>(TState)'. Nullability of type argument 'TState' doesn't match 'notnull' constraint.
