+Apache OpenWhisk Runtime Dotnet is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate [...]

+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+# Apache OpenWhisk runtimes for .NET Core
 
+[![Build Status](https://travis-ci.org/apache/incubator-openwhisk-runtime-dotnet.svg?branch=master)](https://travis-ci.org/apache/incubator-openwhisk-runtime-dotnet)
+
+## Changelogs
+- [.NET Core 2.1 CHANGELOG.md](core/dotnet2.1/CHANGELOG.md)
+
+
+## Quick .NET Core Action
+A .NET Core action is a .NET Core class library with a method called `Main` that has the exact signature as follows:
+
+```csharp
+public Newtonsoft.Json.Linq.JObject Main(Newtonsoft.Json.Linq.JObject);
+```
+
+In order to compile, test and archive .NET Core projects, you must have the [.NET Core SDK](https://www.microsoft.com/net/download) installed locally and the environment variable `DOTNET_HOME` set to the location where the `dotnet` executable can be found.
+
+For example, create a C# project called `Apache.OpenWhisk.Example.Dotnet`:
+
+```bash
+dotnet new classlib -n Apache.OpenWhisk.Example.Dotnet -lang C#
+cd Apache.OpenWhisk.Example.Dotnet
+```
+
+Install the [Newtonsoft.Json](https://www.newtonsoft.com/json) NuGet package as follows:
+
+```bash
+dotnet add package Newtonsoft.Json -v 11.0.2
+```
+
+Now create a file called `Hello.cs` with the following content:
+
+```csharp
+using System;
+using Newtonsoft.Json.Linq;
+
+namespace Apache.OpenWhisk.Example.Dotnet
+{
+    public class Hello
+    {
+        public JObject Main(JObject args)
+        {
+            string name = "stranger";
+            if (args.ContainsKey("name")) {
+                name = args["name"].ToString();
+            }
+            JObject message = new JObject();
+            message.Add("greeting", new JValue($"Hello, {name}!"));
+            return (message);
+        }
+    }
+}
+```
+
+Publish the project as follows:
+
+```bash
+dotnet publish -c Release -o out
+```
+
+Zip the published files as follows:
+
+```bash
+cd out
+zip -r -0 helloDotNet.bin *
+```
+
+You need to specify the name of the function handler using `--main` argument.
+The value for `main` needs to be in the following format:
+`{Assembly}::{Class Full Name}::{Method}`, e.q.,
+`Apache.OpenWhisk.Example.Dotnet::Apache.OpenWhisk.Example.Dotnet.Hello::Main`
+
+### Create the .NET Core Action
+To use on a deployment of OpenWhisk that contains the runtime as a kind:
+```bash
+wsk action update helloDotNet helloDotNet.bin --main Apache.OpenWhisk.Example.Dotnet::Apache.OpenWhisk.Example.Dotnet.Hello::Main --kind dotnet:2.1
+```
+
+### Invoke the .NET Core Action
+Action invocation is the same for .NET Core actions as it is for Swift and JavaScript actions:
+
+```bash
+wsk action invoke --result helloDotNet --param name World
+```
+
+```json
+  {
+      "greeting": "Hello World!"
+  }
+```
+
+## Local development
+```bash
+./gradlew core:dotnet2.1:distDocker
+```
+This will produce the image `whisk/action-dotnet-v2.1`
+
+Build and Push image
+```bash
+docker login
+./gradlew core:action-dotnet-v2.1:distDocker -PdockerImagePrefix=$prefix-user -PdockerRegistry=docker.io
+```
+
+Deploy OpenWhisk using ansible environment that contains the kind `dotnet:2.1`
+Assuming you have OpenWhisk already deploy localy and `OPENWHISK_HOME` pointing to root directory of OpenWhisk core repository.
+
+Set `ROOTDIR` to the root directory of this repository.
+
+Redeploy OpenWhisk
+```bash
+cd $OPENWHISK_HOME/ansible
+ANSIBLE_CMD="ansible-playbook -i ${ROOTDIR}/ansible/environments/local"
+$ANSIBLE_CMD setup.yml
+$ANSIBLE_CMD couchdb.yml
+$ANSIBLE_CMD initdb.yml
+$ANSIBLE_CMD wipe.yml
+$ANSIBLE_CMD openwhisk.yml
+```
+
+Or you can use `wskdev` and create a soft link to the target ansible environment, for example:
+```
+ln -s ${ROOTDIR}/ansible/environments/local ${OPENWHISK_HOME}/ansible/environments/local-dotnet
+wskdev fresh -t local-dotnet
+```
+
+### Testing
+Install dependencies from the root directory on $OPENWHISK_HOME repository
+```bash
+pushd $OPENWHISK_HOME
+./gradlew install
+podd $OPENWHISK_HOME
+```
+
+Using gradle to run all tests
+```bash
+./gradlew :tests:test
+```
+Using gradle to run some tests
+```bash
+./gradlew :tests:test --tests *ActionContainerTests*
+```
+Using IntelliJ:
+- Import project as gradle project.
+- Make sure working directory is root of the project/repo
+
+#### Using container image to test
+To use as docker action push to your own dockerhub account
+```bash
+docker tag whisk/action-dotnet-v2.1 $user_prefix/action-dotnet-v2.1
+docker push $user_prefix/action-dotnet-v2.1
+```
+Then create the action using your the image from dockerhub
+```bash
+wsk action update helloDotNet helloDotNet.bin --main Apache.OpenWhisk.Example.Dotnet::Apache.OpenWhisk.Example.Dotnet.Hello::Main --docker $user_prefix/action-dotnet-v2.1
+```
+The `$user_prefix` is usually your dockerhub user id.

+# Gradle
+
+Gradle is used to build OpenWhisk. It does not need to be pre-installed as it installs itself using the [Gradle Wrapper](https://docs.gradle.org/current/userguide/gradle_wrapper.html). To use it without installing, simply invoke the `gradlew` command at the root of the repository. You can also install `gradle` via [`apt`](http://linuxg.net/how-to-install-gradle-2-1-on-ubuntu-14-10-ubuntu-14-04-ubuntu-12-04-and-derivatives/) on Ubuntu or [`brew`](http://www.brewformulas.org/Gradle) on Mac [...]
+
+## Usage
+
+In general, project level properties are set via `-P{propertyName}={propertyValue}`. A task is called via `gradle {taskName}` and a subproject task is called via `gradle :path:to:subproject:{taskName}`. To run tasks in parallel, use the `--parallel` flag (**Note:** It's an incubating feature and might break stuff).
+
+### Build
+
+To build all Docker images use `gradle distDocker` at the top level project, to build a specific component use `gradle :core:controller:distDocker`.
+
+Project level options that can be used on `distDocker`:
+
+- `dockerImageName` (*required*): The name of the image to build (e.g. whisk/controller)
+- `dockerHost` (*optional*): The docker host to run commands on, default behaviour is docker's own `DOCKER_HOST` environment variable
+- `dockerRegistry` (*optional*): The registry to push to
+- `dockerImageTag` (*optional*, default 'latest'): The tag for the image
+- `dockerTimeout` (*optional*, default 240): Timeout for docker operations in seconds
+- `dockerRetries` (*optional*, default 3): How many times to retry docker operations
+- `dockerBinary` (*optional*, default `docker`): The binary to execute docker commands
+
+### Test
+
+To run tests one uses the `test` task. OpenWhisk consolidates tests into a single `tests` project. Hence the command to run all tests is `gradle :tests:test`.
+
+It is possible to run specific tests using [Gradle testfilters](https://docs.gradle.org/current/userguide/java_plugin.html#test_filtering). For example `gradle :tests:test --tests "your.package.name.TestClass.evenMethodName"`. Wildcard `*` may be used anywhere.
+
+## Build your own `build.gradle`
+In Gradle, most of the tasks we use are default tasks provided by plugins in Gradle. The [`scala` Plugin](https://docs.gradle.org/current/userguide/scala_plugin.html) for example includes tasks, that are needed to build Scala projects. Moreover, Gradle is aware of *Applications*. The [`application` Plugin](https://docs.gradle.org/current/userguide/application_plugin.html) provides tasks that are required to distribute a self-contained application. When `application` and `scala` are used  [...]
+
+In OpenWhisk, we want to distribute our application via Docker images. Hence we wrote a "plugin" that creates the task `distDocker`. That task will build an image from the `Dockerfile` that is located next to the `build.gradle` it is called from, for example Controller's `Dockerfile` and `build.gradle` are both located at `core/controller`.
+
+If you want to create a new `build.gradle` for your component, simply put the `Dockerfile` right next to it and include `docker.gradle` by using
+
+```
+ext.dockerImageName = 'openwwhisk/{IMAGENAME}'
+apply from: 'path/to/docker.gradle'
+```
+
+If your component needs to be build before you can build the image, make `distDocker` depend on any task needed to run before it, for example:
+
+```
+distDocker.dependsOn ':common:scala:distDocker', 'distTar'
+```

+ * Parameters that can be set on project level:
+ * - dockerImageName (required): The name of the image to build (e.g. controller)
+ * - dockerRegistry (optional): The registry to push to
+ * - dockerImageTag (optional, default 'latest'): The tag for the image
+ * - dockerImagePrefix (optional, default 'whisk'): The prefix for the image,
+ *       'controller' becomes 'whisk/controller' per default
+ * - dockerTimeout (optional, default 840): Timeout for docker operations in seconds
+ * - dockerRetries (optional, default 3): How many times to retry docker operations
+ * - dockerBinary (optional, default 'docker'): The binary to execute docker commands
+ * - dockerBuildArgs (options, default ''): Project specific custom docker build arguments
+ * - dockerHost (optional): The docker host to run commands on, default behaviour is
+ *       docker's own DOCKER_HOST environment variable
