How to create Custom C# Code snippet in Visual Studio 2022 or for any version of Visual Studio.

Step 1: XML File Create Karna

1. Ek .snippet file banaiye. Iska extension .snippet hoga.
2. File ke andar aapko ek specific XML structure likhna hoga. Example:

Repository Snippet Example:

<CodeSnippet xmlns="http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet">

  <Header>

    <Title>Repository Snippet</Title>

    <Shortcut>repo</Shortcut>

    <Description>Generic repository implementation.</Description>

    <Author>YourName</Author>

  </Header>

  <Snippet>

    <Declarations>

      <Literal>

        <ID>T</ID>

        <ToolTip>Entity type</ToolTip>

        <Default>MyEntity</Default>

      </Literal>

    </Declarations>

    <Code Language="csharp">

      <![CDATA[

using Microsoft.EntityFrameworkCore;

public class Repository<$T$> : IRepository<$T$> where $T$ : class

{

    private readonly DbContext _context;

    private readonly DbSet<$T$> _dbSet;

    public Repository(DbContext context)

    {

        _context = context;

        _dbSet = _context.Set<$T$>();

    }

    public async Task<IEnumerable<$T$>> GetAllAsync()

    {

        return await _dbSet.ToListAsync();

    }

    public async Task<$T$> GetByIdAsync(int id)

    {

        return await _dbSet.FindAsync(id);

    }

    public async Task<$T$> AddAsync($T$ entity)

    {

        await _dbSet.AddAsync(entity);

        await _context.SaveChangesAsync();

        return entity;

    }

    public async Task<$T$> UpdateAsync($T$ entity)

    {

        _dbSet.Attach(entity);

        _context.Entry(entity).State = EntityState.Modified;

        await _context.SaveChangesAsync();

        return entity;

    }

    public async Task<bool> DeleteAsync(int id)

    {

        var entity = await GetByIdAsync(id);

        if (entity == null) return false;

        _dbSet.Remove(entity);

        await _context.SaveChangesAsync();

        return true;

    }

}

]]>

    </Code>

  </Snippet>

</CodeSnippet>

Step 2: Snippet file ko Folder Me Save Karna

1. Is .snippet file ko Visual Studio snippets folder me save karna hoga. Path:

C:\Users\<YourUsername>\Documents\Visual Studio <Version>\Code Snippets\Visual C#\My Code Snippets

replace YourUsername = windows user name (lenovo), Version = 2022

C:\Users\LENOVO\Documents\Visual Studio 2022\Code Snippets\Visual C#\My Code Snippets

2. Agar My Code Snippets folder nahi hai, to aap manually create kar sakte ho.

Step 3.  restart your PC. 

Step 4. open any cs file type repo + tab + tab key press you get Repository code.
