I tried installing .NET 5 RC2 sdk on Ubuntu 20.04 following the instructions listed here.

When trying to run net5.0 benchmarks using that SDK I'm getting the following failure:

BenchmarkDotNet requires dotnet cli to be installed or path to local dotnet cli provided in explicit way using `--cli` argument, benchmark 'HeapSortBenchmarks.PriorityQueue: DefaultJob [Size=30]' will not be executed

I suspect the issue is due to the fact that the snap installation of the sdk relies on symlinks:

$ ls -l `which dotnet`
lrwxrwxrwx 1 root root 17 Oct 23 13:33 /snap/bin/dotnet -> dotnet-sdk.dotnet

When I try to run the benchmarks using

$ dotnet run -c Release --cli dotnet

I'm getting a similar error:

The provided CliPath "dotnet" does NOT exist.

However if I pass the underlying file:

$ dotnet run -c Release --cli /snap/bin/dotnet-sdk.dotnet

The benchmark executes without issue.

The relevant code doing the detection is here. It is not clear to me whether it is an issue with the heuristic or a System.Diagnostics.Process bug related to symlinks. cc @adamsitnik
