I have the same issue. Did you figure out the solution? Thanks.

I was able to get this working with the SDK 3.1.424 installed alongside of 6.0.402. Had to add a global.json at the root of try-samples like this { "sdk": { "version": "3.1.424" } }

Removed references to the package 'System.CommandLine.Experimental' from all of the .csproj files. Removed the same references in .\try-samples\101-linq-samples\src\obj\project.assets.json Be sure to update any references to the latest SDK to refer to the 3.1.424, ie: in the project.assets.json... "runtimeIdentifierGraphPath": "C:\\Program Files\\dotnet\\sdk\\3.1.424\\RuntimeIdentifierGraph.json"

The first run will give an error but subsequent runs ran without issue.

Hey man, if you managed to solve the issue, is there a way you could upload the working file somewhere? I'd do the modifications myself, but I only really now some C# and SQL, I found this repository through a tutorial but I can't make it work, so I was just wondering if you could help since you've already found a solution.

Hey TallGuy,

The version of .NET SDK you have installed is important. I forked the original dotnet/try-samples repo to here and made the changes for you. For this to work, you still will need to download the latest version of the .Net 3.1.426 SDK located here, afterward, if you haven't done so already, install the dotnet-try tool (same instructions on the README as before). Then when you git clone the repo, you should be able to start a console session in the folder you save it to and run dotnet try. It will open your browser as before but should give you sample output this time.

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.
