Given the diversity of operating systems supported by Docker and the differences between .NET Framework and .NET Core, you should target a specific OS and specific versions depending on the framework you are using.

For Windows, you can use Windows Server Core or Windows Nano Server. These Windows versions provide different characteristics (IIS in Windows Server Core versus a self-hosted web server like Kestrel in Nano Server) that might be needed by .NET Framework or .NET Core, respectively.

For Linux, multiple distros are available and supported in official .NET Docker images (like Debian). In the image below  you can see the possible OS version depending on the .NET framework used.

You can also create your own Docker image in cases where you want to use a different Linux distro or where you want an image with versions not provided by Microsoft. For example, you might create an image with ASP.NET Core running on the traditional .NET Framework and Windows Server Core, which is a not-so-common scenario for Docker.

When you add the image name to your Dockerfile file, you can select the operating system and version depending on the tag you use, as in the following examples:

I have come across this issue of Date and Time  in SharePoint that i feel like writing an email to Microsoft for making this the most confusing thing ever . 

When you create a Date column you have the choice of Date and Date & Time.

Note the keyword “Format” in that option. Even if you select “Date Only”, your users can still type, or copy and paste, a date and a time and it will be stored as a date and time. But… only the date will be displayed.

After considerable amount of wasting my effort and countless guess work, i came to understand that Times are represented as parts of a day.

You should use .NET Core, with Linux or Windows Containers, for your containerized Docker server application when:

•  You have cross-platform needs. For example, you want to use both Linux and Windows Containers.
•  Your application architecture is based on microservices.
• You need to start containers fast and want a small footprint per container to achieve better density or more containers per hardware unit in order to lower your costs.
  

In short, when you create new containerized .NET applications, you should consider.NET Core as the default choice. It has many benefits and fits best with the containers philosophy and style of working. An additional benefit of using .NET Core is that you can run side by side .NET versions for applications within the same machine. This benefit is more important for servers or VMs that do not use containers, because containers isolate the versions of .NET that the app needs. (As long as they are compatible with the underlying OS.)

You should use .NET Framework for your containerized Docker server application when:

•  Your application currently uses .NET Framework and has strong dependencies on Windows.
•  You need to use Windows APIs that are not supported by .NET Core.
• You need to use third-party .NET libraries or NuGet packages that are not available for .NET Core.

Using .NET Framework on Docker can improve your deployment experiences by minimizing deployment issues. This “lift and shift” scenario is important for containerizing legacy applications that were originally developed with the traditional .NET Framework, like ASP.NET WebForms, MVC web apps or WCF (Windows Communication Foundation) services.

Plenty of people have written on this topic and  i'll try to clear out some misconceptions about how you should go about it. Moreover one needs to draw a very clear line about Migration and Upgrading since they are both different which a lot of people seem to mix up. On a lot of forums i see people asking questions like how do we migrate from SP 2007 to SP 2013 and then to 2016?  Another question which is quiet frequent relates to SharePoint 2010 license and if its possible to do a direct migration from SharePoint 2007 to SharePoint 2013.

The issues can be resolved easily and it is not that difficult as it looks like. You only need to go through the post with full attention. So, let us get started.

Oftentimes, it happens with the users that they are currently using SharePoint 2007. But, as the advent of new features and technology, they think of SharePoint to SharePoint migration. Although, it is believed by many users that it mandatory to switch from 2007 to SharePoint 2010 and then, further proceed towards SharePoint 2013 migration. However, it is not true. This post deals with the best possible solution for moving from SharePoint 2007 to 2013 and also gives a chart to show the benefits of SharePoint 2016 and why you should consider it.

I have written very extensively on the topic of Migration to SharePoint Online, in case you are looking for it.
