dotnet-opentk-tutorial's Issues

Running failed

Thanks for putting this up. I've been trying to find some .NET Core OpenGL examples (that run on Linux) and it's been a tad hard to find something that at least builds (this did). But when doing the dotnet run. I was treated with this:

Unhandled Exception: System.MissingMethodException: Method not found: '!0 System.ReadOnlySpan`1.get_Item(Int32)'.

Any idea on how to fix this?
