BenchmarkDotNet v0.10.13 has been released! This release includes:

• Mono Support for DisassemblyDiagnoser: Now you can easily get an assembly listing not only on .NET Framework/.NET Core, but also on Mono. It works on Linux, macOS, and Windows (Windows requires installed cygwin with obj and as). (See #541)

• .NET 4.7.1 support (See 28aa94)
• Support Visual Basic project files (.vbroj) targeting .NET Core (See #626)

There's two ways to deploy a .NET Core application. There's FDD and SCD. Since TLAs (three letter acronyms) are stupid, that's Framework-dependent and Self-contained. When .NET Core is installed it ends up in C:\program files\dotnet on Windows, for example. In the "Shared" folder there's a bunch of .NET stuff that is, well, shared. There may be multiple folders, as you can see in my folder below. You can have many and multiple installs of .NET Core.
