・If you encountered to the error that Visual Studio can’t open service fabric project.
The error logged this message ‘The specified default content type (Default) is not defined in the project item schema’. This error occured when the Service Fabric SDK 2.4.164 with Visual Studio 2015. I recommend use Visual Studio 2017 with last released Service Fabric SDK. The reason is that in present time we have not chance to get old version Service Fabric SDK.
