I created a .net core 7 project using the entity framework core. Well, at that time I installed .net core 6 so my global ef tool was still version 6, then I updated to version 7. Here I had a problem, it said that I had not installed the framework. I decide to uninstall dotnet. Then I reinstalled sdk 7 and global ef tools. And new error appear. I try reinstall many times. But still like this, now I can't use the ef tool.
This is dotnet --info

I found my answer, I change the Root dotnet env which in /usr/share/dotnet for dotnet 7.
Run export DOTNET_ROOT=/usr/share/dotnet

I run the code
dotnet new global.json --sdk-version 3.1.408
but I need to downgrade sdk-version 3.1.0
I deleted global.json folder again
project are developed in ASP .NetCore 3.1
then I try the dotnet new globaljson --sdk-version 3.1.0
If I run dotnet aspnet-codegenerator controller -name EmployeeController -m Employee -dc AppDbContext --relativeFolderPath Controllers --useDefaultLayout --referenceScriptLibraries
I got the following error:
A compatible installed .NET Core SDK for global.json version [3.1.0]
from [/home/dir_name/app1/global.json] was not found Install the
[3.1.0] .NET Core SDK or update [dir_name/app1/global.json] with an
installed .NET Core SDK:
3.1.408 [/snap/dotnet-sdk/123/sdk]
As the error message said, the 3.1.0 .NET Core SDK was not found, I assume you didn't install the 3.1.0 version .NET Core SDK.
Try to use the following command to check the installed SDK version:
dotnet --list-sdks
Then, you could download the 3.1.0 version .NET Core SDK and Runtime and install it.
I installed aspnet core runtime (aspnetcore-runtime-3.1.3) on a centOS 7 server.
following this guide from microsoft documentation: https://learn.microsoft.com/en-us/dotnet/core/install/runtime?pivots=os-linux#download-and-manually-install
my server doesn't have internet connection.
After installation, when I run any command, e.g.
dotnet --info
it says it can't find any installed dotnet sdk:
$ dotnet --info
It was not possible to find any installed .NET Core SDKs
Did you mean to run .NET Core SDK commands? Install a .NET Core SDK from:

Previously, I downloaded the rpm package and installed it with rpm -ivh command, same result
What can I do to fix this?
Note that I don't have internet access in the server
EDIT: The problem: I don't need SDK to run this command or any command I am using.
Anyways I've tried installing SDK, it says it can't find any compatible frameworks
What is the problem? you just installed runtime, and the error says there is no sdk.
You installed the .net runtime but didn't install the any sdk. for you to be able use asp.net core you need to install both. you can visit asp.net core documentation for the difference between them. but you can just visit https://dotnet.microsoft.com/download to download the appropriate sdk you need.
nb: I assume you are doing this from a gui. i'm sure there are commands for installing the asp.net core runtime and SDK from command prompt. but what is important is that YOU ARE MISSING THE SDK!!
I have a DotNet Core 2.2 application that I am trying to get running through IIS. However, I get the following error: HTTP Error 500.0 - ANCM In-Process Handler Load Failure when I try to load the app in my browser.
Upon checking the logs it says the following:
Error:
An assembly specified in the application dependencies manifest (blablabla.deps.json) was not found:
package: 'AutoMapper.Extensions.Microsoft.DependencyInjection', version: '7.0.0'
path: 'lib/netstandard2.0/AutoMapper.Extensions.Microsoft.DependencyInjection.dll'
But I think that's a bit of a red herring.
The following is the output from dotnet --info:

I have tried all of the following:
Changed "AspNetCoreModuleV2" to "AspNetCoreModule" in the
Web.config.
Tried switching AspNetCoreHostingModel=InProcess to
RuntimeFrameworkName=Microsoft.AspNetCore.App in my Web.csproj file.
Cleaning and manually deleting the bin, obj, and .vs folders
My application pool is set to 'No Managed Code' (as the guides all say). At a bit of a loss regarding what to do as I've been through every forum post and github issue on the matter. Also, it is running on my colleagues machine whom has the exact same configuration as me.
One thing to note though, if he creates a copy of his application pool (same settings, basic and advanced, just a different name), and tries to run it on that, it doesn't work either and he gets the same error as me. It only works on the application pool called 'Core AppPool' which was automatically added to IIS upon installation of windows server hosting or the SDK (not sure which).
It seems your application pool identity don't have the enough permission to access your package folder.
I suggest you could try to set the package folder with enough permission by setting the folder's security.
I've got an ASP.NET Core project in my solution, targeting .NET Core 2.1. I've added a global.json file at the solution level:
{
"sdk": {
"version": "2.1.400"
}
}
On the Team City agent, I've installed MSBuild Tools 2017 (15.8.1), including .NET Core Build Tools.
From the command line I can see SDK 2.1.400 is installed on the agent:
>dotnet --list-sdks
2.1.202 [C:\Program Files\dotnet\sdk]
2.1.400 [C:\Program Files\dotnet\sdk]
However, building the solution fails on Team City with the following error:
dashboard.csproj : error : Unable to locate the .NET Core SDK. Check that it is installed and that the version specified in global.json (if any) matches the installed version.
Dashboard.csproj : error MSB4236: The SDK 'Microsoft.NET.Sdk.Web' specified could not be found.
A compatible SDK version for global.json version: [2.1.400] from [X:\agent-1\sandbox1\global.json] was not found
Any idea why it wouldn't find SDK 2.1.400 when building with MSBuild given it's present in the SDK list?
I finally worked out that dotnet was not recognised as a command when running on Team City (despite dotnet being recognised as a command from the prompt, under the same Windows account).
The solution for me was to update the PATH environment variable using Team City parameters:
Name: env.PATH
Kind: Environment Variable
Value: C:\Program Files\dotnet;%env.PATH%
It now works as expected.
Verify that the PATH environment variable points to the location where the SDK is installed (C:\Program Files\dotnet\ for 64-bit/x64 or C:\Program Files (x86)\dotnet\ for 32-bit/x86). The SDK installer normally sets the PATH. Always install the same bitness SDKs and runtimes on the same machine.
One knows how to check if the .net core SDK is installed or not (you need dotnet --version or where dotnet). How about .net core runtime as well as the aspnet core runtime?
PS: since in production we don't need the .net Core SDK
dotnet --info will show the version of the SDK (if installed), the names and versions of all the runtimes that are installed, including the .NET Core runtime and ASP.NET Core runtime.
$ dotnet --info

If you only care about the runtime (.NET Core and ASP.NET Core) versions, you can use dotnet --list-runtimes. This requires a recent-enough version of .NET Core:
$ dotnet --list-runtimes
Microsoft.NETCore.App 2.0.9 [/usr/lib64/dotnet/shared/Microsoft.NETCore.App]
Microsoft.NETCore.App 2.1.1 [/usr/lib64/dotnet/shared/Microsoft.NETCore.App]
I don't have the ASP.NET Core runtime packages installed, so it only shows me the .NET Core runtime.
