Added unit tests covering parsing of Json for all the pieces of the project.json
Added a RawRuntimeOptions to Project and made Executable deserialize that into the runtimeOptions of runtimeconfig.json
Added tests to cover copying runtimeoptions during dotnet build.
- ProjectModel uses AssemblyLoadContext which is only available in netstandard1.5. Moving ProjectModel and all its dependencies up to netstandard1.5.
- Work around our dependencies still being on old CoreFX builds by hoisting System.Runtime.Serialization.Primitives, System.Private.DataContractSerialization, System.Linq.Expressions, and System.Xml.XmlSerializer references to the current version.
Update .exe's project.json Target Framework from dnxcore50 to netstandardapp1.5.
Update .dll's project.json Target Framework from dnxcore50 to netstandard1.3.
Adding workaround for DataContractSerialization to src\dotnet\project.json to fix crossgen issue.
Build 23901 has a dependency issue that doesn't allow the runtime.any.System.Private.DataContractSerialization
package to be restored. When we move to a new build of CoreFX we should take this workaround out.
