BenchmarkDotNet directly throws The handle is invalid exception
Hi,
When trying to run LINQPad Tutorial & Reference/Benchmarking Your Code/Benchmarking - direct.linq
I'm getting "The handle is invalid "exception.
I'm using LINQPad 7 v7.5.16 X64
Any idea how to fix this?

Comments
This is a bug/issue in BenchmarkDotNet 0.13.3. I've logged the issue, so hopefully it will be fixed in the next release.
In the meantime, you can work around this by using BenchmarkDotNet 0.13.2. From NuGet Package Manager, click "Download different version" and choose 0.13.2.
The PR I submitted for BenchmarkDotNet has been accepted, so this should work again in 0.13.4.
