BenchmarkDotNet.Tool in .NET Core 2.2

[wryczko]

I cannot run benchmarks written in .NET Core 2.2 using BenchmarkDotNet.Tool, because it says it is implemented in older (2.1) version.

This is what I get when trying to run it for a netstandard 2.1 library:

$ dotnet benchmark Benchmarks.dll

Unhandled Exception: System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types.
Could not load file or assembly 'netstandard, Version=2.1.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. The system cannot find the file specified.
