AzureDevOps/VSTS Build - Could not find version number data in BUILD_BUILDNUMBER

Question

Setting up a simple class library to build and publish to VSTS\'s own feed, I see this error when the NuGet package runs.

Could not find version number da

Answer 1

I had a variable in my .nuspec file:

Build#$build$

that was incorrectly parameterized in the package build step. With the package step open in the build editor, I expanded the 'Advanced' section added to 'Additional Build Properties' this text

build=$(Build.BuildNumber)
