Same problem.

I try to run 101 LINQ Samples. It fails to pass dotnet try verify in the beginning and luckily I fix it by adding global.json in \try-samples-main\101-linq-samples. However, even though the verification is passed without any error, the code samples cannot output the expected computation results in the webpage's consoles, but only displays the red bar, completely same as Kuuo's and others' situation.

My Attempt:

1. At first, I failed to run "dotnet try verify". It threw the exception:

2. Then, I create the file global.json in \try-samples-main\101-linq-samples(In the beginning, I try to put the global.json in the \try-samples-main, but it does no help to the verification at all), written with

  {
      "sdk": {
        "version": "3.0.103"
      }
  }

This measure helps it pass the dotnet try verify. All samples are favorably compiled and tell me Found 0 error(s) as a consequence. My machine environment (by dotnet --info) is as below.

3. Unfortunately, after passing the verification and typing dotnet try to run, a red bar is still displayed when I click to run any code sample in Chrome 107.0.5304.107 (Official Build) (64-bit).

I just started diving into Linq, and I ran into this exact same issue. Is there any workaround until it gets fixed?

Currently facing the same issue too. :(

Thankfully following this guide: https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/concepts/linq/walkthrough-writing-queries-linq works well enough that you can copy-paste the 101-linq-samples into that small project and learn LINQ well enough.

Although I hope they still fix the issue with the 101-linq-samples eventually...

Thank you very much for your sharing, helps me a lot. Let's hope they will fix this issue soon...

[pyrocumulus]

I am facing this issue as well, not with the linq examples but just with running:

dotnet try demo

The server starts fine and I get the pages I am supposed to see. But the snippets provided there, also only output a red background and nothing else.

If I run verify on the demo application, I get all sorts of errors:

Just to clarify
I also have this problem using Option 2: starting from scratch. Verify also returns the exact same error.
