Namespace roots

A namespace root pins a namespace as the base of the output folder hierarchy and places its output under a named base folder. When a type’s namespace equals a configured root or starts with that root followed by a dot, the root prefix is stripped and the remainder is placed under the specified folder.

This is an alternative to CratisProxiesSegmentsToSkip that works by name rather than by a fixed segment count, making it more resilient when namespace depths vary across a project.

Configuration

<ItemGroup>
    <NamespaceRoot Include="features" Namespace="MyApp.Features" Folder="features" />
</ItemGroup>

Attribute	Description
Include	MSBuild item identity; the generator reads the metadata below, not this name
Namespace	The C# namespace prefix to match
Folder	Output base folder; an empty value intentionally strips the namespace prefix without adding a folder

Example: With namespace root MyApp.Features → features:

C# namespace	Output folder
MyApp.Features.Auth.Registration	features/Auth/Registration/
MyApp.Features.Billing.Invoices	features/Billing/Invoices/
MyApp.Features.Auth	features/Auth/
MyApp.Features	features/
MyApp.Other	(falls back to segment-skip logic — namespace root does not apply)

Multiple roots

You can declare multiple roots. The longest matching namespace wins:

<ItemGroup>
    <NamespaceRoot Include="features" Namespace="MyApp.Features" Folder="features" />
    <NamespaceRoot Include="shared" Namespace="MyApp.SharedTypes" Folder="shared" />
</ItemGroup>

Priority

Namespace roots only take effect for types whose namespace matches the root. Types that do not match any configured root fall back to CratisProxiesSegmentsToSkip as normal.

These XML blocks belong inside the existing project’s Project element. Namespace roots affect output folders and the slice location of commands and queries, not conventional API routes.

CLI

With the executable alias prerequisite, pass one or more --namespace-root flags using = to separate the namespace from the folder:

proxygenerator assembly.dll output-path --skip-output-deletion \
  --namespace-root=MyApp.Features=features \
  --namespace-root=MyApp.SharedTypes=shared
