ABP Studio: Modular Monolith Solution Template
ABP Studio's modern solution wizard includes a dedicated Modular Monolith architecture. Under the hood, it uses the modern no-layers application template for the main application, then enables modularity automatically.
This page documents the modern modular monolith path. If you are working with the classic template family, see the Solution Template Selection Guide for the host + module composition approach.
What ABP Studio Creates
When you choose Modular Monolith in the modern solution wizard, ABP Studio:
- creates the main application by using the modern no-layers host template.
- locks the solution into modular mode.
- creates a
mainfolder in the solution model and moves the main application into it. - creates a
modulesfolder for reusable module solutions. - lets you add additional modules during solution creation and optionally install them into the main application immediately.
Typical Layout
In ABP Studio's Solution Explorer, the solution is organized around these areas:
main: the main application and its host-side assets.modules: one module solution per business capability.etc: shared infrastructure, run profiles, and deployment files.
Additional modules are generated under the solution's modules/<module-name> directory, while the main application remains the single deployable host.
How Modules Fit In
The module solutions created for a modular monolith use the same reusable module concepts documented in the Application Module Template page.
Use this template when you want:
- clear module boundaries without a distributed deployment model.
- separate module solutions for teams or business domains.
- a monolith today, with a cleaner path toward microservices later.
