NuGet Error NU5029
NuspecProperties should be in the form of 'key1=value1;key2=value2'.
Issue
Properties passed to msbuild -t:pack -p:NuspecFile=project.nuspec
command were not in the right format to be parsed.
Solution
Please pass any nuspec properties using -p:NuspecProperties
in the format of key=value
. For instance msbuild -t:pack -p:NuspecFile=project.nuspec -p:NuspecProperties="configuration=release"
