I'm trying to get my dotnet Core application running on an ubuntu 18.04LTS machine with dotnet core runtime installed.
The command:
dotnet myapp.dll
The result:
Did you mean to run dotnet SDK commands? Please install dotnet SDK from:
https://go.microsoft.com/fwlink/?LinkID=798306&clcid=0x409
As far as I understand I do not need the SDK for simply running this application. Just the runtime should suffice, right?
dotnet --info
Host (useful for support):
Version: 2.2.8
Commit: b9aa1abc51
.NET Core SDKs installed:
No SDKs were found.
.NET Core runtimes installed:
Microsoft.NETCore.App 2.2.8 [/usr/share/dotnet/shared/Microsoft.NETCore.App]
To install additional .NET Core runtimes or SDKs:

How to make this work without installing an SDK?
It actually worked. I was running the dotnet command with the wrong path.. myapp.dll was nested a bit deeper. My mistake.

I have an error in my build pipeline on Azure DevOps. The project called DevPortalWeb fails in the Publish step.
The project is upgraded to netcore3.1 (it was created with earlier version).
DevPortalWeb -> C:\agent\_work\13\s\Application\DevPortalWeb\bin\release\netcoreapp3.1\DevPortalWeb.dll
DevPortalWeb -> C:\agent\_work\13\s\Application\DevPortalWeb\bin\release\netcoreapp3.1\DevPortalWeb.Views.dll
It was not possible to find any compatible framework version
The framework 'Microsoft.NETCore.App', version '2.0.0-preview1-002111-00' (x64) was not found.
- The following 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.NETCore.App&framework_version=2.0.0-preview1-002111-00&arch=x64&rid=win10-x64

##[error]Error: The process 'C:\Program Files\dotnet\dotnet.exe' failed with exit code 1
What could be a reason, that the build pipeline requires previous version of the framework? There is no reference to version '2.0.0-preview1-002111-00' in the project now.
The problem was, that project was migrated from .NET Core 2.2 to .NET Core 3.1.
Several packages, including this one, do not target this version anymore. This is already included in version 3.0.
The migration documentation lists which packages are obsolete:

Having issues with Ubuntu 20.04. I followed official instruction and installed both SDK & runtime. If can be confirmed from the terminal:
dotnet --list-sdks
3.1.403 [/usr/share/dotnet/sdk]
and runtime:
dotnet --list-runtimes
Microsoft.AspNetCore.App 3.1.9 [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 3.1.9 [/usr/share/dotnet/shared/Microsoft.NETCore.App]
...yet the project I am trying to dotnet run requires the Microsoft.AspNetCore.App 2.2.8 as can be seen from the log:
It was not possible to find any compatible framework version
The framework 'Microsoft.AspNetCore.App', version '2.2.8' was not found.

What's the correct way to install missing SDKs and runtimes?
So it comes out that Ubuntu 20.04 is not supported for above-mentioned runtime and one have to install them manually.
In my particular case it was enough to download binaries and run them as usual.
Error: A fatal error occurred. The required library libhostfxr.so could not be found. If this is a self-contained application, that library should exist in [/home/alanee/.dotnet/tools/.store/dotnet-ef/3.1.3/dotnet-ef/3.1.3/tools/netcoreapp3.1/any/]. If this is a framework-dependent application, install the runtime in the global location [/usr/share/dotnet] or use the DOTNET_ROOT environment variable to specify the runtime location or register the runtime location in [/etc/dotnet/install_location].
The .NET Core runtime can be found at: - https://aka.ms/dotnet-core-applaunch?missing_runtime=true&arch=x64&rid=ubuntu.20.04-x64

When i run dotnet --info in the output i get host version: 3.0.3
What is it?
Recently i have installed and later deleted dotnet sdk 3.0 version, but host version is still 3.0.3 does it affect running my program in 2.2 version of sdk?
I'm running on a macOS and the project I'm working on just upgraded from .NET Core 2 to .NET Core 3. The problem is that I can no longer build my project in Rider. If I try to build it in the terminal using dotnet build, the build succeeds. In my project, there are some subprojects that use netstandard2, but this should not be a problem (as its working in the terminal). I'm getting the following error message:
Project1 is not compatible with netcoreapp3.0 (.NETCoreApp,Version=v3.0). Project2 supports: netstandard2.1 (.NETStandard,Version=v2.1)
I have tried to add a global.json file which specifies I'm using version 3 of .NET Core, but it didn't help.
If I'm running dotnet build once in the terminal, then the new build of Rider will succeed. So things are working, but it is just annoying to always build in the terminal first.
The output of dotnet --info:

I found that the issue was in Rider. The workaround is to change PackageReference Restore Engine (in File > Settings > Build, Execution, Deployment > NuGet) to MSBuild.
The issue will be fixed in a later version of Rider, so it is recommended to switch back to Embedded after the version is relased. The difference between MSBuild and Embedded:
MSBuild just calls external MSBuild task; Embedded directly calls
NuGet API inside Rider process. Embedded should work much faster and
it provides additional logs which can be useful when restore fails
The reason for the issue:
[...] because Rider 2019.2 EAP2 still used NuGet 4.9 internally; this
version doesn't have proper support of .NET Core 3.0 / .NET Standard
2.1. In Rider 2019.2 RTM, we are going to upgrade the internal version of NuGet up to 5.1.
