How to create a new module for Virto Commerce Platform v3 from scratch? Follow the steps to create a “Dummy module”.

## 1. Create a well-structured solution and projects

1. Create empty **_DummyModule_** solution: [https://docs.microsoft.com/en-us/visualstudio/get-started/tutorial-projects-solutions?view=vs-2019##create-a-solution](https://docs.microsoft.com/en-us/visualstudio/get-started/tutorial-projects-solutions?view=vs-2019##create-a-solution)
2. Add **_src_** and **_tests_** Solution Folders (using Visual Studio)
3. In **_src_** add project using “_Class library (.NET Core)_” template:
  1. Project name: **_DummyModule.Core_**
  2. Location: …\_DummyModule\ **src** _ folder (create the missing **src** folder).

4. Add **_DummyModule.Data_** and **_DummyModule.Web_** projects in the same way, just ensure they are located under **src** folder.
5. Delete the auto-generated Class1.cs from all projects.
6. In **_tests_** add project using “_xUnit Test Project (.NET Core)_” template:
  1. Project name: **_DummyModule.Tests_**
  2. Location: …\_DummyModule\ **tests** _ folder (create the missing **tests** folder).

7. Set “Target framework” to “.NET Core 2.2” for all 4 projects.
8. References to projects:
  1. **DummyModule.Data** : add reference to DummyModule.Core project
  2. **DummyModule.Web** : add references to DummyModule.Core, DummyModule.Data projects
  3. **DummyModule.Tests** : add references to DummyModule.Core, DummyModule.Data, DummyModule.Web projects

9. References to NuGet packages:
  1. **DummyModule.Core** : add reference to latest version 3 (3.x) **_VirtoCommerce.Platform.Core_** package.
  2. **DummyModule.Data** : add reference to latest version 3 (3.x) **_VirtoCommerce.Platform.Data_** package.

10. References to NuGet packages in **_VirtoCommerce.Platform.Web_** :
  1. (Double click in Visual Studio to) open _DummyModule.Web.csproj_ file for editing;
  2. Add new ItemGroup:

```auto
<ItemGroup>
  <PackageReference Include="Microsoft.AspNetCore.App" />
</ItemGroup>

```

11. Compile the solution (there should be no warnings).

## 2. DummyModule.Core

1. ModuleConstants.cs (permissions, settings)
2. Models

## 4. DummyModule.Web

Did you use latest version fo vc-build?  
Did you add localizaion file to project?

Could you share with us your source code? We will check what’s wrong.

Most of the VC modules has localization file, like [Catalog Module](https://github.com/VirtoCommerce/vc-module-catalog/tree/dev/src/VirtoCommerce.CatalogModule.Web/Localizations) and we use Virto Commerce CLI (vc-build) to create package.

Hi  
this issue is resolved when we change the localization file name file name was en.PrescriptionModule.json but module name is NB.PrescsriptionModule so we change the name of localization file name to en.NB.PrescriptionModule.json after changing the name it was resolved

Thanks
