Subject Re: What's the blessed way to compile REEF.NET right now?

I will explain what I know about this problem.

The Microsoft.Avro.Core / Microsoft.Avro.Tools nuget packages require the
10.x version json and I had this all working by having both the 8.x and
10.x in the same packages.config file like this:

  <package id="Microsoft.Avro.Core" version="0.1.0"
targetFramework="net451" developmentDependency="true" />
  <package id="Microsoft.Avro.Tools" version="0.1.0"
targetFramework="net451" developmentDependency="true" />
  <package id="Newtonsoft.Json" version="10.0.3" targetFramework="net451"
developmentDependency="true" />
  <package id="Microsoft.Hadoop.Avro" version="1.5.6"
targetFramework="net45" />
  <package id="Newtonsoft.Json" version="8.0.3" targetFramework="net45" />
  <package id="StyleCop.MSBuild" version="" targetFramework="net45"
developmentDependency="true" />

Note that the 10.x version is marked as a development dependency which
builds and tests properly from the command line.

msbuild .\lang\cs\Org.Apache.REEF.sln

msbuild .\lang\cs\TestRunner.proj

Julia or Maria found a problem where the running tests from visual studio
would not run with an error about duplicate entries in packages.config
file. I discovered that if you build in visual studio, delete the json 10.x
line from the packages.config file, and run the tests in visual studio, the
tests run fine in visual studio. This shows that visual studio is not
respecting the development dependency flag like msbuild does.

Since msbuild handles both the build and testing properly with json 10.x as
a development dependency, and running tests in visual studio is only be for
debugging purposes for which there is a work around until we upgrade all of
REEF to json 10.X when we go to the new project files, we should reverse
REEF-1832 that removed the json 10.x entry.
