Clone the [Rhino3dmIO_docfx](https://github.com/mcneel/rhinocommon/tree/rhino3dmio_docfx) branch.\r\n2. Open [Rhino3dmIO.csproj](https://github.com/mcneel/rhinocommon/blob/rhino3dmio_docfx/dotnet/Rhino3dmIO.csproj) in Visual Studio 2017. Ensure docfx.console NuGet 2.22.1 package is restored.\r\n3. Build Rhino3dmIO.csproj. Error will be logged.\r\n\r\n**Expected Behavior**:\r\nThe .csproj builds and docfx builds documentation\r\n\r\n**Actual Behavior**:\r\n.csproj builds without docfx. With docfx .csproj does not build, docfx doesn't generate anything, and am getting an error related to metadata extraction with a message saying \r\n\r\n> Object reference not set to an instance of an object\r\n\r\nHere is the log:\r\n\r\n`{\"message\":\"Config file \\\"C:\\\\dev\\\\github\\\\mcneel\\\\RhinoCommonPublic\\\\dotnet/docfx.json\\\" is used.\",\"date_time\":\"2017-08-10T11:33:02.9761644Z\",\"message_severity\":\"verbose\"}\r\n{\"message\":\"Loading project C:/dev/github/mcneel/RhinoCommonPublic/dotnet/Rhino3dmIO.csproj\",\"source\":\"MetadataCommand.ExtractMetadata\",\"file\":\"C:/dev/github/mcneel/RhinoCommonPublic/dotnet/Rhino3dmIO.csproj\",\"date_time\":\"2017-08-10T11:33:03.2421879Z\",\"message_severity\":\"verbose\",\"correlation_id\":\"8B277620-A634-4D4A-AF2E-B09DC7DB6EB3.1.1.1\"}\r\n{\"message\":\"Completed Scope:MetadataCommand in 7431.5706 milliseconds.\",\"source\":\"MetadataCommand\",\"date_time\":\"2017-08-10T11:33:10.5679949Z\",\"message_severity\":\"info\",\"correlation_id\":\"8B277620-A634-4D4A-AF2E-B09DC7DB6EB3.1.2\"}\r\n{\"message\":\"Error extracting metadata for C:/dev/github/mcneel/RhinoCommonPublic/dotnet/Rhino3dmIO.csproj: Object reference not set to an instance of an object.\",\"date_time\":\"2017-08-10T11:33:10.5689535Z\",\"message_severity\":\"error\",\"correlation_id\":\"8B277620-A634-4D4A-AF2E-B09DC7DB6EB3.2\"}\r\n{\"message\":\"Completed in 7436.4121 milliseconds\",\"date_time\":\"2017-08-10T11:33:10.5698447Z\",\"message_severity\":\"info\",\"correlation_id\":\"8B277620-A634-4D4A-AF2E-B09DC7DB6EB3.3\"}\r\n`\r\nAny better way to debug this?
