How do I prevent Visual Studio 2019 adding blank lines between using statements

After updating Visual Studio 2019 to version 16.7.0 a few days ago, I noticed that it started creating annoying blank lines between using directives if the first part of the namespace is not the same.

For example:

using System;

using Alpha;
using Alpha.Foo;
using Alpha.Bar;

using Bravo;
using Bravo.Utils;

Assuming you are talking about C# source code/files, then: Select "Options" from the "Tools" menu and, in the displayed pop-up, navigate to "Text Editor ... C# ... Advanced" and uncheck the "Separate using directive groups" check-box, as shown below:

There is also an option via .editorconfig which is supported since a while in Visual Studio. The benefit is that this setting is "re-usable" across IDEs and can be brought into source control.

The relevant options are:

  • dotnet_separate_import_directive_groups
  • dotnet_sort_system_directives_first

See dotnet-formatting-options for more details.

The rule IDE0055 reflects formatting issues.

Add these lines to your .editorconfig to change the behavior for C# and VisualBasic

#### .NET Coding Conventions ####
[*.{cs,vb}]

# Organize usings
dotnet_separate_import_directive_groups = false
dotnet_sort_system_directives_first = false

# https://learn.microsoft.com/de-de/dotnet/fundamentals/code-analysis/style-rules/ide0055
dotnet_diagnostic.IDE0055.severity = error

I found out, that new classes with using do respect the setting. Old existing classes, will not show a warning / error when there is a space between two using blocks. You need to find and clean dirty code yourself.
