The net core sdk cannot be located как исправить

Introduction

This page contains more information about the error:

The .NET Core SDK cannot be located. .NET Core debugging will not be enabled. Make sure the .NET Core SDK is installed and is on the path.

What this error means is that this extension ran the command dotnet and dotnet was NOT found on the PATH within the extension’s process.

If you don’t have the .NET Core SDK installed, fixing this error is usually simple enough: visit https://dot.net/core-sdk-vscode to download and install the .NET Core SDK.

If you do have the .NET Core SDK installed, then this means that the directory containing dotnet (Linux and macOS) or dotnet.exe (Windows) is not on your PATH, at least in this extension’s process. The rest of this page will provide advice on understanding why.

Known issues

Before we get to a list of troubleshooting steps, lets first enumerate a few known reasons why this error happens:

1. If you very recently installed the .NET SDK —
   • If you had Visual Studio Code open at the time you installed the .NET SDK, and you haven’t restarted it, you should do so.
   • On Windows, on some machines, environment variable changes don’t immediately take effect. Restart your computer to see if that resolves this problem.
2. If the .NET SDK was installed through Linux Snap — see Linux Snap instructions

General troubleshooting steps on Linux/Mac

The first step in troubleshooting this problem is to see if this problem also happens is a terminal/shell. After you have launched a terminal or shell, type in which dotnet.

If which dotnet produces a PATH, then the .NET SDK was able to successfully modify the PATH, but VS Code isn’t picking it up. VS Code attempts to scrape the environment by launching the default shell under the covers. But this process can be fragile. You can attempt to work around this by starting VS Code from your Terminal. Alternatively, you can attempt to debug VS Code to understand what is going wrong — at this time at least, the function to debug is getUnixShellEnvironment. Lastly, you could manually add a symbolic link from within a directory which is on the PATH in all processes to wherever dotnet is installed (see below for instructions).

If which dotnet produces no output, then this means the .NET SDK wasn’t able to modify the PATH or add a symbolic link, or the .NET SDK for your platform doesn’t do so. You can fix this by either adding a symbolic link yourself (example: sudo ln -s /usr/share/dotnet/dotnet /usr/bin/dotnet where /usr/share/dotnet/dotnet should be replaced with wherever the .NET SDK installer for your platform was installed to), or by modifying your PATH manually (example: modify ~/.bashrc add add something like export PATH=$PATH:/new/directory/here).

General troubleshooting steps on Windows

First, as mentioned above, if you installed the .NET SDK since you last rebooted Windows, you might start by just rebooting to see if that fixes things.

Otherwise, you can start troubleshooting this problem is to see if this problem also happens is a command prompt:

• Start a command prompt:
  • Hit WinKey+R to bring up the Windows run dialog
  • Type in cmd.exe
• When the command prompt starts, type in where.exe dotnet.

If the result of running where.exe is that a path to dotnet.exe is printed (example: C:Program Filesdotnetdotnet.exe) then the .NET SDK has successfully added itself to the Windows Path. There are no known reasons why PATH wouldn’t be propagated to the VS Code process. You could try starting VS Code from the command prompt to see if that helps.

If the result of running where.exe is a message like INFO: Could not find files for the given pattern(s). then the .NET SDK wasn’t able to add itself to the PATH. You could try uninstalling and reinstalling the .NET SDK. You could also try examining the default path with the following steps:

• Bring up System Properties:
  • Windows 10 — On the Start Menu, search for ‘This PC’ and bring up properties
  • Before — On the Start Menu, search for ‘My Computer’ and bring up properties
• Go to the Advanced settings
• Click the button for ‘Environment Variables’
• Find ‘Path’ in either the user or system list
• See if the dotnet.exe directory (example: C:Program Filesdotnet) is in the list. If not you could add it.
• If it is in the list, you could see if maybe another directory has added it self incorrectly (example: added an opening quote without a trailing quote), or if the set of environment variables has grown very large — there is a limit of 32,767 total characters.

Note about 64-bit installs of the .NET SDK

In 64-bit environments the .NET SDK will fail to be discovered if the 32-bit dotnet path comes before the 64-bit dotnet path in the Environment PATH variable. Try removing the 32-bit path entirely from your PATH variable and relaunch VS Code to see if your issue is resolved.

Special instructions

Linux Snap instructions

The Linux Snap packages for the .NET Core SDK, by default, will not create the dotnet link. To do so, run sudo snap alias dotnet-sdk.dotnet dotnet. More information about this can be found in the .NET Core SDK release notes.

Note that, as of the time of this writing, there are also other incompatibilities between this extension and the .NET Core SDK Snap package beyond the dotnet PATH issue. This incompatibility may result in:

Some projects have trouble loading. Please review the output for more details.
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:
https://aka.ms/dotnet-download

More information about this problem can be found in dotnet/cli#12110.

Some community members have been successful in using the Snap install by following the instructions listed in Configuring Snap installs of dotnet-sdk.

Another possible workaround is to add the following to ~/.omnisharp/omnisharp.json.

{
    "MSBuild": {
        "UseLegacySdkResolver": true
    }
}

For those of you who are on macOS and on M1, and after they closed VS Code and re-installed it, still don’t get rid of the error. Try this:

On VS Code, click «Open folder…» and open your user folder. For example my name is Bob and here is the path of my user folder: «Macintosh HD/Users/bob».

Once the user folder is opened, on the left browser panel of VS Code, open those hidden files:

.bash_profile

.zshrc

and at the end of those files, add this:

export PATH=»/usr/local/share/dotnet:$PATH»

And save those 2 files.

Basically, it allows apps trying to find .NET SDK to find it in the folder «/usr/local/share/dotnet» which is the default installation folder on macOS Ventura 13.1 (and some previous versions I don’t know lol).

To be honest, only one of these two files needs this new line but I’m to lazy to figure out which one.

Restart your Mac and it should work.

But the method provided by this official document did not solve my problem. . . . . .
1，Introduction
What does the «The .NET Core SDK cannot be located error report» mean? It tells you that dotnet and dotnet was NOT found on the PATH, dotnet is not found on the path, although you have already added environment variables.
2，Known issues
Reason for error:
1. If VSCODE is opened while installing .NET SDK, try restarting VSCODE after installing .NET SDK
2. On some windows machines, environment variables will not take effect immediately, restart the computer
3，General troubleshooting steps on Windows
Open a DOS window and enter where.exe dotnet

If the installation path of dotnet.exe is displayed, it means that it has been successfully added to the window path. The official document indicates that it is not known why VSCODE does not recognize it, and an error The .NET Core SDK cannot be located will be reported.

If you finish typing the where.exe dotnet command, INFO: Could not find files for the given pattern(s) is displayed, indicating that the .NET SDK is not added to the path, please uninstall and reinstall the .NET SDK

Okay, let’s talk about how I solved it
download link

Both must be downloaded and installed,
The first is Microsoft Visual C++ 2015 Redistributable Update 3.

1. After opening, it looks like this, click Download

Second, check X64, click NEXT to select the path to install

The second is KB2533623
download link
One, it looks like this after opening, download

Second, you can also directly Baidu KB3071756, enter the download link, the downloaded file is like this

Third, after installing the above two, restart the computer, it is normal, and no more errors will be reported.
