Create Abp Io Template

Available Templates

1. Application Template (app)

Standard layered application for most scenarios.

Use Cases:

• Medium to large applications
• Multiple developers or teams
• Long-term maintainability required
• Complex business domains

Command:

abp new <solution-name> -t app [options]

2. Single-Layer Template (app-nolayers)

Simplified template for small applications.

Use Cases:

• Small project with simple requirements
• 1-3 developers team
• Temporary or POC projects
• No expected growth in complexity

Command:

abp new <solution-name> -t app-nolayers [options]

3. Microservice Template (microservice)

For distributed microservice architectures.

Use Cases:

• Very large distributed systems
• Independent deployment needed
• Multiple technology stacks
• High scalability requirements

Command:

abp new <solution-name> -t microservice [options]

4. Empty Template (empty)

Minimal template for custom solutions.

Use Cases:

• Custom architecture requirements
• Learning ABP framework
• Minimal starting point

Command:

abp new <solution-name> -t empty [options]

Template Selection Guide

Decision Tree

1. Project Size & Complexity

• Small/Simple → Single-Layer
• Medium/Complex → Layered
• Large/Distributed → Microservice

2. Team Size

• 1-3 developers → Single-Layer
• 4+ developers → Layered
• Multiple teams → Microservice

3. UI Requirements

• Web only → MVC
• SPA experience → Angular
• Modern web → Blazor
• No UI needed → no-ui

4. Database Needs

• Relational → EF Core
• Document → MongoDB

public class Book : FullAuditedAggregateRoot<Guid>
{
    public string Name { get; set; }
    public BookType Type { get; set; }
    public DateTime PublishDate { get; set; }
    public float Price { get; set; }
    
    protected Book() { }
    
    public Book(
        Guid id, 
        string name, 
        BookType type, 
        DateTime publishDate, 
        float price) : base(id)
    {
        Name = Check.NotNullOrWhiteSpace(name, nameof(name));
        Type = type;
        PublishDate = publishDate;
        Price = price;
    }
}

5. Application Service

// src/Acme.BookStore.Application/Books/BookAppService.cs
public class BookAppService : ApplicationService, IBookAppService
{
    private readonly IRepository<Book, Guid> _bookRepository;

    public BookAppService(IRepository<Book, Guid> bookRepository)
    {
        _bookRepository = bookRepository;
    }

    public async Task<PagedResultDto<BookDto>> GetListAsync(GetBooksInput input)
    {
        var queryable = await _bookRepository.GetQueryableAsync();
        
        var books = await AsyncExecuter.ToListAsync(
            queryable
                .WhereIf(!input.Filter.IsNullOrWhiteSpace(), 
                    book => book.Name.Contains(input.Filter))
                .OrderBy(book => book.Name)
                .PageBy(input.SkipCount, input.MaxResultCount)
        );

        var totalCount = await AsyncExecuter.CountAsync(
            queryable.WhereIf(!input.Filter.IsNullOrWhiteSpace(), 
                book => book.Name.Contains(input.Filter))
        );

        return new PagedResultDto<BookDto>(
            totalCount,
            ObjectMapper.Map<List<Book>, List<BookDto>>(books)
        );
    }
}

Troubleshooting

Common Issues and Solutions

1. CLI Not Found

# Install ABP CLI
dotnet tool install -g Volo.Abp.Cli

# Check PATH
echo $PATH

# Reinstall if corrupted
dotnet tool uninstall -g Volo.Abp.Cli
dotnet tool install -g Volo.Abp.Cli

2. Template Creation Fails

# Check .NET SDK version
dotnet --version

# Clear NuGet cache
dotnet nuget locals all --clear

# Use specific template version
abp new Acme.BookStore -t app --use-open-source-template

3. Database Issues

# Check connection string
dotnet ef database update --verbose

# Recreate database
dotnet ef database drop
dotnet ef database update

# Check migrations
dotnet ef migrations list

4. Build Errors

# Clean and rebuild
dotnet clean
dotnet restore
dotnet build

# Check for package conflicts
dotnet list package --outdated
