'OperationRequest' does not contain a definition for 'TraceContext' and no accessible extension method 'TraceContext' accepting a first argument of type 'OperationRequest' could be found (are you missing a using directive or an assembly reference?)

'OperationResult' does not contain a definition for 'StartTimeUtc'

'OperationResult' does not contain a definition for 'EndTimeUtc'

'OperationResult' does not contain a definition for 'StartTimeUtc'

'OperationResult' does not contain a definition for 'EndTimeUtc'

'SendSignalOperationAction' does not contain a definition for 'RequestTime'

'SendSignalOperationAction' does not contain a definition for 'ParentTraceContext'

'StartNewOrchestrationOperationAction' does not contain a definition for 'RequestTime'

'StartNewOrchestrationOperationAction' does not contain a definition for 'ParentTraceContext'

The best overload for 'EmitRequestMessage' does not have a parameter named 'requestTime'

Unable to validate code scanning workflow: error: getWorkflow() failed: Error: Expected to find a code scanning workflow file at D:\a\durabletask-dotnet\durabletask-dotnet\.github\workflows\codeQL.yml, but no such file existed. This can happen if the currently running workflow checks out a branch that doesn't contain the corresponding workflow file.

Nullability in constraints for type parameter 'TState' of method 'TestLogger.BeginScope<TState>(TState)' doesn't match the constraints for type parameter 'TState' of interface method 'ILogger.BeginScope<TState>(TState)'. Consider using an explicit interface implementation instead.

Nullability of reference types in return type of 'IDisposable? TestLogger.BeginScope<TState>(TState state)' doesn't match implicitly implemented member 'IDisposable ILogger.BeginScope<TState>(TState state)' (possibly because of nullability attributes).
