+# ### Define variables
+#
+variables:
+  # 1) Name of directory where restore and build objects are stored.
+  OBJECTS_DIRECTORY: 'obj'
+  # 2) Name of directory used for keeping restored dependencies.
+  NUGET_PACKAGES_DIRECTORY: '.nuget'
+  # 3) A relative path to the source code from project repository root.
+  # NOTE: Please edit this path so it matches the structure of your project!
+  SOURCE_CODE_PATH: '*/*/'
+
+# ### Define global cache rule
+#
+# Before building the project, all dependencies (e.g. third-party NuGet packages)
+# must be restored. Jobs on GitLab.com's Shared Runners are executed on autoscaled machines.
+#
+# Each machine is used only once (for security reasons) and after that is removed.
+# This means that, before every job, a dependency restore must be performed
+# because restored dependencies are removed along with machines. Fortunately,
+# GitLab provides cache mechanism with the aim of keeping restored dependencies
+# for other jobs.
+#
+# This example shows how to configure cache to pass over restored
+# dependencies for re-use.
+#
+# With global cache rule, cached dependencies will be downloaded before every job
+# and then unpacked to the paths as specified below.
+cache:
+  # Per-stage and per-branch caching.
+  key: "$CI_JOB_STAGE-$CI_COMMIT_REF_SLUG"
+  paths:
+    # Specify three paths that should be cached:
+    #
+    # 1) Main JSON file holding information about package dependency tree, packages versions,
+    # frameworks etc. It also holds information where to the dependencies were restored.
+    - '$SOURCE_CODE_PATH$OBJECTS_DIRECTORY/project.assets.json'
+    # 2) Other NuGet and MSBuild related files. Also needed.
+    - '$SOURCE_CODE_PATH$OBJECTS_DIRECTORY/*.csproj.nuget.*'
+    # 3) Path to the directory where restored dependencies are kept.
+    - '$NUGET_PACKAGES_DIRECTORY'
+  #
+  # 'pull-push' policy means that latest cache will be downloaded (if it exists)
+  # before executing the job, and a newer version will be uploaded afterwards.
+  # Such a setting saves time when there are no changes in referenced third-party
+  # packages.
+  #
+  # For example, if you run a pipeline with changes in your code,
+  # but with no changes within third-party packages which your project is using,
+  # then project restore will happen quickly as all required dependencies
+  # will already be there — unzipped from cache.
+
+  # 'pull-push' policy is the default cache policy, you do not have to specify it explicitly.
+  policy: pull-push
+
+# ### Restore project dependencies
+#
+# NuGet packages by default are restored to '.nuget/packages' directory
+# in the user's home directory. That directory is out of scope of GitLab caching.
+#
+# To get around this, a custom path can be specified using the '--packages <PATH>' option
+# for 'dotnet restore' command. In this example, a temporary directory is created
+# in the root of project repository, so its content can be cached.
+#
+# Learn more about GitLab cache: https://docs.gitlab.com/ee/ci/caching/index.html
