I use NswagStudio to generate a C#-Client by the swagger.json. If I generate the C#-Client I will get always the error messages that the functions UpdateJsonSerializerSettings() and CreateHttpRequestMessageAsync() aren't available in this context.
I checked the generated client-file and didn't find these functions. This is obviously the reason.
My question is how I can generate these both functions with NswagStudio too like all the other functions?

After read the nwsagstudio source code, I found I have changed the nwsagstudio definition file and set
"generateUpdateJsonSerializerSettingsMethod": trueThis resolved my issue.
