Restore fails for netcoreapp5.0 projects

[kerams]

Paket does not like the .NET 5 preview released the other day, in particular it does not recognize netcoreapp5.0 references in paket.dependencies and fsproj files.

Is there also a new netstandard? kerams <notifications@github.com> schrieb am Mi., 18. März 2020, 07:06:

I don't see any mention of it in the announcement blog post.

[forki]

ok it's now part of the new alpha version. Please let me know if it works

[kerams]

Strangely, it doesn't:

Paket version 6.0.0-alpha019
Performance:
 - Runtime: 345 milliseconds
Paket failed with
-> Extracting platforms from path 'netcoreapp5.0' failed, a newer Paket version might support it, otherwise please open an issue for a missing platform handler.

Paket failed with

[forki]

can you please copy your deps file into this?

[forki]

so what's the package that's making trouble?

[kerams]

It's not a package-specific problem:

paket restore --project .\src\Server\Server.fsproj
Paket version 6.0.0-alpha019
Performance:
 - Runtime: 120 milliseconds
Paket failed with
-> Error in paket.dependencies line 3
     Could not parse framework 'netcoreapp5.0'. Try to update or install again or report a paket bug.

install fails too.

[forki]

6.0.0-alpha020 has yet another fix

[kerams]

Looks good now, many thanks!

<TargetFramework>net5.0</TargetFramework>

is accepted by the project tooling and likely the future version identifier for .net 5.0 apps

I think I heard @cartermp talk about it also but not 100% sure.

[cartermp]

Yes, net5.0 is the base TFM. There will be net5.0-ios and so on for other TFMs though. You can read about it here: https://devblogs.microsoft.com/dotnet/announcing-net-5-preview-4-and-our-journey-to-one-net/
