Microsoft.Extensions.* 2.0 to target .NET Standard 2.0 #249
Description
The Microsoft.Extensions.* 2.0 packages will change to target .NET Standard 2.0 only. This means you will be able to use these 2.0 packages on:
- .NET Framework 4.6.1 and up
- .NET Core 2.x
- Mono 5.x
There will be a period of time during which other .NET platforms will need to catch up to .NET Standard 2.0, e.g. a UWP version with support for .NET Standard 2.0 will arrive later this year, as announced at Build.
Microsoft.Extensions.* 1.x versions target .NET Framework 4.5.1 and .NET Standard 1.x and can still be used with older platforms. The documentation on .NET Standard contains a full matrix of .NET platform support.
Why do we want to do this?
Because:
- ASP.NET Core 2.0 and Entity Framework Core 2.0 which are the main downstream dependents of these packages have already moved to .NET Standard 2.0
- it simplifies our compatibility story for the long term,
- reduces the size of the Microsoft.Extensions.* packages and all its dependencies significantly,
- and prevents Microsoft.Extensions.* 2.0 packages from falsely appearing to be compatible with platforms on which we are not doing any testing.
