I've been trying to find a solution to the red rectangle network error console output when practicing c# on Microsoft learn interactive tutorial but can't seem to find the solution. Any help would be appreciated. Thanks.

I just forked this and made changes to the files to support version 3.1.426 of the SDK for someone else. Seems to be a common issue here with this repo. You can get that SDK here. After you install that along with the dotnet-try tool, try my forked version try-samples to see if that helps.

I met the similar thing in my Computer too, the issue is solved with below steps:

The enviornment:

OS: Win 11

.NET SDKs: .NET Core 3.0 SDK, .NET Core 3.1 SDK, .NET 6.0 SDK, .NET 8.0 SDK installed.

1.Make sure you installed lastest version of "dotnet try" tool.

If you install it with the command "dotnet tool install -g dotnet-try", you need unistall it first with:

dotnet tool uninstall -g dotnet-try

If you install it with the command "dotnet tool install -g Microsoft.dotnet-try", you need unistall it first with:

dotnet tool uninstall -g Microsoft.dotnet-try

Then install the latest verion of "dotnet try" with below command:

dotnet tool install -g --add-source "https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet-tools/nuget/v3/index.json" Microsoft.dotnet-try

In Windows, recommand to run above commands in "cmd" with admin permission.

2.Make sure you installed .NET 3.0 and .NET 3.1 SDKs

You can run below command to check:

dotnet --list-sdks

If you did not install them, download from below links and install them.

https://dotnet.microsoft.com/en-us/download/dotnet/3.0 https://dotnet.microsoft.com/en-us/download/dotnet/3.1

Note: .NET core 3.1 SDK's version is "3.1.416" so far.

3.Clone code with below command using git shell

git clone https://github.com/dotnet/try-samples

4.Create global.json at the root of the folder "try-samples":

The content is below:

{
  "sdk": {
    "version": "3.1.416"
  }
}

Note: the version "3.1.416" here should be the same as in step 2.

5.Try to compile it with "dotnet try verify" command

cd try-samples/
dotnet try verify

If no exceptions happened, jump to next step below. Else try to remove references to the package 'System.CommandLine.Experimental' from all of the .csproj files.

6.Run "dotnet try" command to open the web in browser:

dotnet try ".\101-linq-samples"

7.Try the examples from Web.

May it be helpful for you.
