asp.net core 2.1 on arch linux does not run

I have installed the latest version of the .net core using pacman on an Arch Linux:

sudo pacman -S dotnet-sdk

Running dotnet --info shows the correct version:

Host (useful for support):
  Version: 2.1.0
  Commit:  caa7b7e2ba

.NET Core SDKs installed:
  2.1.0 [/opt/dotnet/sdk]
  2.1.300 [/opt/dotnet/sdk]

I can run console applications, but when I run dotnet run in an ASP.NET Core directory return this error:

It was not possible to find any compatible framework version The specified framework 'Microsoft.AspNetCore.App', version '2.1.0' was not found.

Why though versions seem to match, it doesn't run?

More details:

ls /opt/dotnet/sdk/ returns:

2.1.300  NuGetFallbackFolder

Contents of the .csproj file:

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.App" />
  </ItemGroup>

</Project>

This question is old, but in case someone's trying to get .NET 5 to run on Arch, this can give you another solution.

If you build, publish and run the project specifying the platform runtime, dotnet will build a self-contained application, with all necessary platform specific dependencies.

You can do that with the --runtime/-r flag.

Examples for Arch:

dotnet build -r linux-x64

dotnet run -r linux-x64

dotnet publish -r linux-x64

Refer to Microsoft docs for the available runtime identifiers: https://learn.microsoft.com/en-us/dotnet/core/rid-catalog

Edit:

I've also had less problems with paths using the AUR package instead of Snap's:

https://aur.archlinux.org/packages/dotnet-sdk-bin/

Edit 2:

After installing AUR's aspnet-runtime-bin package, all errors about Microsoft.AspNetCore.App not being found disappeared, without using the --runtime flag:

https://aur.archlinux.org/packages/aspnet-runtime-bin

Upgrading all the packages solved the problem:

pacman -Syu

It includes the dotnet-sdk package 2.1.300-2 updated on 2018-06-12 11:24 UTC: https://www.archlinux.org/packages/community/any/dotnet-sdk/

I had a similar issue trying to get global tools installed. Creating a symlink worked for me:

ln -s /opt/dotnet/ /usr/share/dotnet

@tura08 answer is wrong, because .NET Core should work on Arch Linux like on every other Linux system.

I was experiencing same issue so I just reported it https://github.com/dotnet/core-setup/issues/4216 and it seems dotnet-sdk package is missing aspnetcore-runtime-2.1 dependency. I wrote email to maintainer, so I hope he will fix package soon.

.NET Core is not currently supported on Arch, so there's no guarantees that it will work at all. Currently the following distros are supported on 64-bit:

  • Red Hat Enterprise Linux 7, 6
  • CentOS 7
  • Oracle Linux 7
  • Fedora 27
  • Debian 9, 8.7 or later versions
  • Ubuntu 18.04, 17.10, 16.04, 14.04
  • Linux Mint 18, 17
  • openSUSE 42.3 or later versions
  • SUSE Enterprise Linux (SLES) 12 Service Pack 2 or later
  • Alpine Linux 3.7 or later versions

See this page for more info.

You can see these issues related to Arch in the dotnet repos:

https://github.com/dotnet/corefx/issues/19447

I don't have a proper solution for your problem but maybe a workaround. I am using elementary os and .net core 2.1 works just fine, but I noticed that my path to the metapackages is different from yours:

.NET Core SDK (reflecting any global.json):
 Version:   2.1.300
 Commit:    adab45bf0c

Runtime Environment:
 OS Name:     elementary
 OS Version:  0.4.1
 OS Platform: Linux
 RID:         linux-x64
 Base Path:   /usr/share/dotnet/sdk/2.1.300/

Host (useful for support):
  Version: 2.1.0
  Commit:  caa7b7e2ba

.NET Core SDKs installed:
  2.0.0 [/usr/share/dotnet/sdk]
  2.1.300 [/usr/share/dotnet/sdk]

You could try to copy the metapackages from your installation folder /opt/dotnet/shared to /usr/share/dotnet/shared

This guy over here has a similar problem using Fedora: https://github.com/dotnet/core-setup/issues/4022
