Docs: Write a document clarifying what .NET 5 is

[davidfowl]

Help us make content visible
We don't have a document that clarifies what .NET 5 is and what is in it. This information is scattered in a couple of blog posts but there's no coherent article about it.

Describe the new article

• The article is needed because lots of people are under the impression that .NET 5 is compatible with .NET Framework 4.8 and thus think it will contain things like webforms, workflow, wcf server etc.

• What is .NET 5?

  • What about .NET Standard?
  • Compatibility matrix of frameworks (set of frameworks that work and don't where, WCF, WebForms, WinForms, Workflow etc)
  • Naming of ASP.NET Core and EntityFramework Core (still has the Core suffix)
  • Target framework compatibility (it's a successor to .NET Core, not .NET Framework)

• https://devblogs.microsoft.com/dotnet/introducing-net-5/

• https://visualstudiomagazine.com/blogs/data-driver/2019/05/net-5-wcf.aspx

I would like to see a section about mobile app development with .NET 5 too.

I think it's time to discriminate packages in nuget between Legacy Framework and .NET.

I think it's time to discriminate packages in nuget between Legacy Framework and .NET.

That's been part of nuget since the beginning, it's called a target framework. Now nuget could do a better job about allowing filtering based on that compatibility.

@welly87 the intent of this issue was to give feedback on the above doc proposal for .NET 5 (which is almost finished), not to discuss features or ask general questions about .NET as a whole.

Various features described in those blog posts about .Net 5 have been dropped or pushed off (java interop? ,aot?). This should be clarified along with the future pipeline for these features.

I would like to know how multi-platform development will be handled. I understand there will be a compatibility matrix with this overview, but will that matrix be implemented in nuget? Meaning if I mark a project as targeting linux and windows, will I still be able to install platform specific nuget packages.

Spell out the support policy and the implications of not being LTS

e.g. if you adopt .NET 5 you have to plan to do the work to move to 5.1 by date X and then upgrade to 6 by date Y

This is quite a change for who is coming from framework so I think it needs to be highlighted to avoid surprises

Does .net 5 = still follow the architectural layout of framework/standard/core e.g. would you mentioned .net core when speaking in the context of .net 5 and is C# 8 the go to language.
