The framework 'Microsoft.AspNetCore.App', version '5.0.0' was not found. when it is installed and inside $PATH
Feb 21
I am working in Manjaro Linux.
I have a .NET Core project. The solution builds fine when I run dotnet build .
However, when I run:
dotnet-ef update --project Bejebeje.DataAccess --startup-project Bejebeje.Mvc
I get the following strange error:
Build started...
Build succeeded.
It was not possible to find any compatible framework version
The framework 'Microsoft.AspNetCore.App', version '5.0.0' was not found.
- No frameworks were found.
You can resolve the problem by installing the specified framework and/or SDK.
The specified framework can be found at:
- https://aka.ms/dotnet-core-applaunch?framework=Microsoft.AspNetCore.App&framework_version=5.0.0&arch=x64&rid=manjaro-x64
It is strange because I already have the SDKs and runtimes for .NET 5.0 installed.
bejebeje|feature/upgrade-to-net-5 ⇒ dotnet --list-sdks
3.1.108 [/usr/share/dotnet/sdk]
5.0.103 [/usr/share/dotnet/sdk]
bejebeje|feature/upgrade-to-net-5 ⇒ dotnet --list-runtimes
Microsoft.NETCore.App 3.1.8 [/usr/share/dotnet/shared/Microsoft.NETCore.App]
Microsoft.NETCore.App 5.0.3 [/usr/share/dotnet/shared/Microsoft.NETCore.App]

Why is this happening? and what can I do to solve the problem?

I had the same problem. You need to have an ASP.NET runtime.
It's a bit confusing and easily overlooked, but it says you need an Microsoft.AspNetCore.App runtime, and your dotnet --list-runtimes only lists Microsoft.NETCore.Apps.
The ArchWiki mentions:
This is caused because the runtime is shipped as a separate package in Arch. You just need to make sure you have the
aspnet-runtimepackage installed as well.
To install the .NET 5 runtime:
sudo pacman -Sy aspnet-runtime
or if you need the 3.1 version:
sudo pacman -Sy aspnet-runtime-3.1
Now there's an ASP runtime available:
$ dotnet --list-runtimes
Microsoft.AspNetCore.App 5.0.4 [/usr/share/dotnet/shared/Microsoft.AspNetCore.App] # <<<
Microsoft.NETCore.App 5.0.4 [/usr/share/dotnet/shared/Microsoft.NETCore.App]
