Last night I was developing some code in .NET Core for the Dutch Azure Meetup and I was (again) encountering versioning problems and unexpected behavior.

I found this blog post which describes in some way the same problem I had.

What the blog post says is that if you use:

dotnet new

{
 "sdk": {
 "version": "1.0.0-preview2-003121"
 }
}

The SDK’s in Windows are installed in the Program Files folder (or Program Files (x86) if you have a 32bit Windows) so let’s take a look there:

• • 1.0.0-preview2-003131
  • 1.0.0-preview2-003133
  • 1.0.0-preview2-003156
  • 1.0.0-preview4-004233

• 1.0.0-preview2-1-003177

But how I know which SDK belongs to which .NET Core version? Continue reading “Demystifying .NET Core SDK versions” →
