Update: I saw that the problem come from Kaspersky Antivirus, so when I disable the antivirus, the error is gone. But this is not a good solution , I would like to know how can I add an except for the localhost??

I have this issue now as well, where the network tab of my browser says:

{
"exception": "System.AggregateException: One or more errors occurred. (Unsupported log file format. Latest supported version is 9, the log file has version 13.)" ...,
"message": "An unhandled exception occurred."
}

Also, dotnet try verify fails to verify my project:

...
Unhandled exception: System.AggregateException: One or more errors occurred. (Unsupported log file format. Latest supported version is 9, the log file has version 13.)
 ---> System.NotSupportedException: Unsupported log file format. Latest supported version is 9, the log file has version 13.
   at ...

And, I have a déjà vu: I believe I have experienced this error roughly a year ago with "latest supported version 7, but log file has version 9" or similar.

It seems that it worked fine with the .NET Core SDK 3.1.409, but then broke for me after installing the .NET Core SDK 3.1.410. And now it does not work anymore since I have the Microsoft.NETCore.App 3.1.16 runtime installed on my machine. It still works fine on a different machine, where I still have the Microsoft.NETCore.App 3.1.15 runtime installed.

[jonsequitur]

Yup, this looks like it's due to a change in the log format for MSBuild. We'll look into whether we can support multiple versions and/or roll forward to .NET 5.

I have same probleme, if any one can help please

[ssedlak]

I can't tell if I am missing something or something is wrong that I can't fix. Uncaught (in promise) Error

[MaartenGDev]

global.json can be used to fix the log version error.

I used the following steps to fix the "Unsupported log format error":

1. Install preview version of dotnet try (source: https://github.com/dotnet/try/blob/main/DotNetTryLocal.md)

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

2. Clone sample repo

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

3. Create global.json inside the try-samples folder

   touch global.json

4. Place the following contents in global.json in the try-samples folder. Use the latest .NET 3.1 that you have installed (dotnet --list-sdks)

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

5. Run dotnet try in the try-samples folder:

   dotnet try

The internal server errors should be fixed. Run dotnet try verify if any other error occurs.

[ssedlak]

@MaartenGDev I did everything except I was not able to clone the repo. I tried to just add the json into my existing directory, but still a red box.

[MaartenGDev]

@ssedlak2278 This error happens if you do not have a SSH key configured in your GitHub profile. You can try cloning using:

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

You need to follow the steps in https://github.com/dotnet/try/issues/938#issuecomment-1023604536 again after cloning the repository.

[ssedlak]

@MaartenGDev It worked! Thank you. I did have to restart my brower before it worked, probably because I've had it open a week.

dotnet try

The internal server errors should be fixed. Run dotnet try verify if any other error occurs.

Doesn't help for me, tried in multiple browsers as well. Verify outputs a bunch of errors for me as well.

It would be neat if there were a docker-image with a known working configuration so one could pull and run that image and just run the samples without worrying about problems in local environments.

I run MacOS and have tried in Chrome as well as Safari.

[MaartenGDev]

@Hultner which version of .NET 3.1 do you have installed? Can be checked using dotnet --list-sdks?

[Hultner]

@Hultner which version of .NET 3.1 do you have installed? Can be checked using dotnet --list-sdks?

$ dotnet --list-sdks
2.2.105 [/usr/local/share/dotnet/sdk]
2.2.204 [/usr/local/share/dotnet/sdk]
3.0.100 [/usr/local/share/dotnet/sdk]
3.1.416 [/usr/local/share/dotnet/sdk]
6.0.101 [/usr/local/share/dotnet/sdk]

Looks like 3.1.416, which I also added to the global.json file according to your instructions.

[cherepo]

Same error on a Mac (not M1)

2.2.207 [/usr/local/share/dotnet/sdk] 3.1.413 [/usr/local/share/dotnet/sdk] 3.1.416 [/usr/local/share/dotnet/sdk] 5.0.202 [/usr/local/share/dotnet/sdk] 5.0.401 [/usr/local/share/dotnet/sdk] 5.0.405 [/usr/local/share/dotnet/sdk] 6.0.200 [/usr/local/share/dotnet/sdk]

This works for me, Thanks. I'm on a win10.

[vasveone]

Just added the global.json as advised from @MaartenGDev in my project folder and works fine!

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

[yimaiyan]

same error in macOS(not M1), as advised from @MaartenGDev in my project folder but failed to fix this issue. Can anyone help? Thanks!

BIG LOVE! BRO

[cheema-corellian]

I followed the instructions in this comment

At first it did not fix my problem. dotnet try verify did not run successfully. The browser still showed red. I then restarted my browser, and the red box in the browser went away. Success!

Here is what my global.json looks like:

{
  "sdk": {
    "version": "7.0.402"
  }
}

For me, it is OK to ignore the dotnet try verify errors, for now.

[Godaday]

This is the process I followed to resolve the error, for your reference.

mkdir mydoc

cd mydoc

dotnet new console -n myApp -f netcoreapp3.1

cd myApp 

create a new file "global.json"

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

in file version node content look your local sdk list

dotnet --list-sdks

 cd mydoc

create file doc.md

# My Interactive Document:

```cs --source-file ./myApp/Program.cs --project ./myApp/myApp.csproj

```shell
dotnet try verify
dotnet try

it's worked
