Chapter 5. Support

The .NET Core 1.0 Getting Started Guide focuses on helping Windows and Linux developers understand what’s required to stand up .NET Core 1.0 on Red Hat Enterprise Linux and complete a basic Hello World! validation to prove that the environment is operational.

The guide’s scope is limited to the minimum information needed to successfully install the .NET Core 1.0 framework on Red Hat Enterprise Linux 7; it is not intended to teach Linux. The assumption is that many Windows developers won’t have extensive Linux experience, so extra assistance deploying software to a Red Hat Enterprise Linux environment will be necessary. See Red Hat Enterprise Linux documentation to learn more about Red Hat Enterprise Linux system administration. When applicable, we can advise the developer to get help from an experienced Linux System Administrator on topics such as understanding Red Hat Enterprise Linux Server 7 components, architecture, permissions, security, file systems, and storage.

Documentation to support Linux developers focuses on setting up .NET Core 1.0 on Red Hat Enterprise Linux 7 and confirming the installation with a Hello World! output. It also provides a quick overview of .NET Core 1.0 with a link to microsoft.com learning resources. Several key motivations include the breadth of the .NET Core market for hosting workloads previously limited to Linux environments and the extent of .NET Core documentation and learning resources. Staffing options now extend to developers without previous Linux experience. One challenge includes understanding the basics of .NET Core architecture and requirements. It is also reasonable to assume the Windows developer tools, interfaces, conventions, and sources of information may be unfamiliar to Linux developers.

5.1. .NET Core 1.0 Support Overview
Copy link

Red Hat and Microsoft are committed to providing excellent support for .NET Core and are working together to resolve any problems that come up from either side. At a high level, Red Hat supports the installation, configuration, and running of the .NET Core component in Red Hat OpenShift Container Platform and Red Hat Enterprise Linux. If it’s a runtime issue, we’re responsible for getting the customer an answer. Red Hat can also provide "commercially reasonable" support for issues we can help with, for instance, NuGet access problems, permissions issues, firewalls, and application questions that we might know the answer to. If it’s a defect or vulnerability in .NET Core, we let Microsoft know about it.

.NET Core 1.0 is supported on Red Hat Enterprise Linux 7 and OpenShift Container Platform versions 3.3 and later.

5.2. Length of Support
Copy link

Developers can use either the Long Term Support (LTS) releases or Current releases. LTS releases are normally major releases (for example, 1.0) and only receive critical fixes. Current releases are minor releases (for example, 1.0.x) and receive the same fixes. They will also be revised when compatible innovations and features are available.

LTS releases are supported for 3 years after the general availability date or 1 year after the general availability of a subsequent LTS release.

According to Microsoft, Current releases are supported within the same 3-year window as the parent LTS release. They are supported for 3 months after the general availability of a subsequent Current release and 1 year after the general availability of a subsequent LTS release. See Microsoft’s .NET Core Support Lifecycle Fact Sheet for more details.

5.3. Who Do I Contact?
Copy link

There are a couple of ways you can get support, depending on how you are using .NET Core.

Integrated Support is a collaborative support agreement between Red Hat and Microsoft. Customers using Red Hat products in Microsoft Azure are mutual customers, so both companies are united to provide the best troubleshooting and support experience possible.

5.4. Frequently Asked questions
Copy link

Here are four of the most common support questions for Integrated Support.

  1. When do I access Integrated Support?

    You can engage Red Hat Support directly. If the Red Hat Support Engineer assigned to your case needs assistance from Microsoft, the Red Hat Support Engineer will collaborate with Microsoft directly without any action required from you. Likewise on the Microsoft side, they have a process for directly collaborating with Red Hat Support Engineers.

  2. What happens after I file a support case?

    Once the Red Hat support case has been created, a Red Hat Support Engineer will be assigned to the case and begin collaborating on the issue with you and your Microsoft Support Engineer. You should expect a response to the issue based on Red Hat’s Production Support Service Level Agreement.

  3. What if I need further assistance?

    Contact Red Hat Support for assistance in creating your case or with any questions related to this process. You can view any of your open cases here.

  4. How do I engage Microsoft for support for a Microsoft Azure platform issue?

    If you have support from Microsoft, you can open a case using whatever process you typically would follow. If you don’t have support with Microsoft, you can always get support from Microsoft here.
