I upgraded my azure function sdk from 1.0.14 to 1.0.28 and I get this build error:
The ExtensionsMetadataGenerator package was not imported correctly.
I can't find any documentation or ways to resolve it.
According to the 1.0.28
function sdk released several day ago, it may have some bugs in it.
Workaround:
Manually adding the Microsoft.Azure.WebJobs.Script.ExtensionsMetadataGenerator nuget package to your project and it will work well.
