+  # [WORKAROUND]
+  #
+  # SYNOPSIS:
+  #
+  # dotnet-cli has introduced a bug with .NET Core RTM (wasn't there till RC2);
+  # that is, the dotnet-run command ignores --framework option and therefore
+  # demands mono PCL reference assemblies to be present on Unix systems, even
+  # though when we intend to build for netcoreapp or netstandard TxM.
+  #
+  # See: https://github.com/dotnet/cli/issues/3658
+  #
+  # The workaround is to rewrite the JSON without net451 framework node in the
+  # runnable (or testable) project's JSON file for CI. This work around must be
+  # applied before executing dotnet-restore command.
+  #
+  # Written in JavaScript to be executable with node.js
+  # (JavaScript being the most native langauge for JSON processing)
+  #
+  # Travis CI job when running under different langauge provides nvm (the node.js version manager)
+  # but not node.js itself. So we first run:
+  #
+  # > $HOME/.nvm/nvm.sh
+  #
+  # then install stable node
+  #
+  # > nvm install stable && nvm use stable
+  #
+  # now, we have node.js in PATH. We will run the following program in evaluation
+  # mode as one-liner:
+  #
+  # ```javascript
+  # // the file to manipulate
+  # jsonPath = './test/NUnit.Portable.Agent.Tests/project.json';
+  #
+  # // read and parse JSON as object (aka CommonJS magic)
+  # data = require(jsonPath);
+  #
+  # // FileSystem API handle
+  # fs = require('fs');
+  #
+  # // delete framework 45 key from the object
+  # delete data.frameworks.net45;
+  #
+  # // write back to file
+  # fs.writeFileSync(jsonPath, JSON.stringify(data, null, 2));
+  # ```
+  # Now the actual one-liner (compressed) version:
+  #
+  - if test "$TRAVIS_OS_NAME" == "linux"; then
+      nvm install stable && nvm use stable;
+    fi
+  - node -e "jsonPath='./test/NUnit.Portable.Agent.Tests/project.json';data=require(jsonPath);fs=require('fs');delete data.frameworks.net45;fs.writeFileSync(jsonPath, JSON.stringify(data, null, 2))"
