Install-Package SimpleSOAPClient in old Projects - Error

[filipedias]

The package 'SimpleSOAPClient' tried to add a framework reference to 'System.Runtime' which was not found in the GAC.

This bug can be solved with following code in project.json:
"
.....
".NETPortable,Version=v4.5,Profile=Profile111": {
"buildOptions": {
"define": [ "PORTABLE45" ]
},
"frameworkAssemblies": {
"mscorlib": "",
"System": { "type": "build" },
"System.Collections": { "type": "build" },
"System.Core": { "type": "build" },
"System.IO": { "type": "build" },
"System.Linq": { "type": "build" },
"System.Net.Http": { "type": "build" },
"System.Runtime": { "type": "build" },

"System.Xml.ReaderWriter": { "type": "build" },
"System.Xml.XDocument": { "type": "build" },
"System.Xml.XmlSerializer": { "type": "build" }
}
},

}
},

As indicated, that is a known bug from NuGet (NuGet/Home#3103) that should be fixed soon. But assigning the { "type": "build" } doesn't make any harm and I'll include it in the next release.

In the meantime, you can manually add the following entry to packages.config and the package restore should work:

<package id="SimpleSOAPClient" version="2.0.0-rc03" targetFramework="net46" />
