Well I've disabled the 'Feature Extension Runtime' extension and that gets rid of the Feature Builder dialog, but I still get the Parse error.
I've updated the the Enlistment directory using TortoiseHg Update command and I'm now on revision 5552, but building is still giving me this error:
Parser Error Message: Error compiling module "Orchard.Packaging" from file "/OrchardLocal/Modules/Orchard.Packaging/Orchard.Packaging.csproj":
The assembly reference 'NuGet.Core, Version=18.104.22.168, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL' could not be loaded.
There are generally a few ways to solve this issue:
1. Remove the assembly reference from the project file if it's not needed.
2. Ensure the assembly reference is present in the 'bin' directory of the module.
3. Ensure the assembly reference is present in the 'bin' directory of the application.
4. Specify the strong name of the assembly (name, version, culture, publickey) if the assembly is present in the GAC.
Re item 2 above I can see that NuGet.Core.dll is not in the Packaging module bin folder (\OrchardEnlistment\src\Orchard.Web\Modules\Orchard.Packaging\bin), if I'm looking in the right place or, for item 3, under the application bin folder (\OrchardEnlistment\src\Orchard.Web\bin).
I can see NuGet.Core.dll under lib path (\OrchardEnlistment\lib\nuget) and it's version 1.1, but other than that I'm not clear on why it's not making it through.
