Unexpected error in .NET Core 3.1 when running "Collect metrics" sample from MS documentation

### Description

The ["Collecting metrics" article](https://learn.microsoft.com/en-us/dotnet/core/diagnostics/metrics-collection) on MS Learn lists that all of its steps should be compatible with .NET Core 3.1 or later. However, I get an `Unsupported Command Exception` any time I target a .NET Core 3.1 app with `dotnet-counters`.

My version of the sample in .NET Core 3.1 is available [here](https://github.com/zsharp-gls/metric-instr)

When I run the .NET Core 3.1 version, this is the output when I try to use dotnet-counters:

```
PS C:\Users\zsharp> dotnet-counters monitor -n metric-instr HatCo.HatStore

```

I also created a branch targeting .NET 5.0, available [here](https://github.com/zsharp-gls/metric-instr/tree/net-5). When I run the same command against the .NET 5.0 version, it works just fine.
