i want to add nuget packages to my portable class library project ,
then i add a project.json to my portable class library project ,but vs 2017 build failed, error message is following:
Your project is not referencing the ".NETPortable,Version=v4.5,Profile=Profile259" framework. Add a reference to ".NETPortable,Version=v4.5,Profile=Profile259" in the "frameworks" section of your project.json, and then re-run NuGet restore.
so ,i search from bing, i got a post:
https://forums.xamarin.com/discussion/80045/error-using-nuget
then i add following json to project.json file:".NETPortable,Version=v4.5,Profile=Profile259": {}
and keep only ".NETPortable,Version=v4.5,Profile=Profile259": {}" under "frameworks" node,like this:
{
"dependencies": {
"Portable.MvvmLightLibs": "5.0.2"
},
"frameworks": {
".NETPortable,Version=v4.5,Profile=Profile259": {}
},
"runtimes": {
"win": {}
}
}
then,i build my project again,it success!
