**Issue description**
The .EditorConfig file only has limited formatting rules for VB only below
```
[*.{cs,vb}]
charset = utf-8-bom
[*.vb]
# Modifier preferences
visual_basic_preferred_modifier_order = Partial,Default,Private,Protected,Public,Friend,NotOverridable,Overridable,MustOverride,Overloads,Overrides,MustInherit,NotInheritable,Static,Shared,Shadows,ReadOnly,WriteOnly,Dim,Const,WithEvents,Widening,Narrowing,Custom,Async:suggestion
```

**Target framework**
N/A
Check the .NET target framework(s) being used, and include the version number(s).

- [X] .NET Core
- [X] .NET Framework
- [X] .NET Standard

If using the .NET Core SDK, include `dotnet --info` output. If using .NET Framework without the .NET Core SDK, include info from Visual Studio's **Help** > **About Microsoft Visual Studio** dialog.

All the require style for VB samples is missing
dotnet --info output or About VS info
