This is how you can use EmbedResourceCSharp .

The code that you start with is

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net7.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
  <ItemGroup>
    <None Remove="createDB.txt" />
  </ItemGroup>

  <ItemGroup>
    <EmbeddedResource Include="createDB.txt" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="EmbedResourceCSharp" Version="1.1.3">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
  </ItemGroup>

</Project>

The code that you will use is

// See https://aka.ms/new-console-template for more information
using System;
using System.Text;

var value = EmbeddingResourceCSharpDemo.MyResource.GetContentOfCreate();
StringBuilder sb = new ();
foreach (byte b in value)
{
    sb.Append((char)b);
}
;
//EncodingExtensions.GetString(Encoding.UTF8,value);
Console.WriteLine(sb.ToString());

namespace EmbeddingResourceCSharpDemo;

public partial class MyResource
{
    [EmbedResourceCSharp.FileEmbed("createDB.txt")]
    public static partial System.ReadOnlySpan<byte> GetContentOfCreate();
}

create database Andrei;
GO;
use Andrei;

The code that is generated is

namespace EmbedResourceCSharp
{
    internal enum PathSeparator
    {
        AsIs,
        Slash,
        BackSlash,
    }

    [global::System.AttributeUsage(global::System.AttributeTargets.Method,AllowMultiple = false)]
    internal sealed class FileEmbedAttribute : global::System.Attribute
    {
        public string Path { get; }

        public FileEmbedAttribute(string path)
        {
            Path = path;
        }
    }

    [global::System.AttributeUsage(global::System.AttributeTargets.Method,AllowMultiple = false)]
    internal sealed class FolderEmbedAttribute : global::System.Attribute
    {
        public string Path { get; private set; }
        public string Filter { get; private set; }
        public global::System.IO.SearchOption Option { get; private set; }
        public PathSeparator Separator { get; private set; }

        public FolderEmbedAttribute(string path,string filter = "*",global::System.IO.SearchOption option = global::System.IO.SearchOption.AllDirectories,PathSeparator separator = PathSeparator.Slash)
        {
            Path = path;
            Filter = filter;
            Option = option;
            Separator = separator;
        }
    }
}

namespace EmbeddingResourceCSharpDemo
{
    public partial class MyResource
    {
        public static partial global::System.ReadOnlySpan<byte> GetContentOfCreate()
        {
            return new byte[] { 239,187,191,99,114,101,97,116,101,32,100,97,116,97,98,97,115,101,32,65,110,100,114,101,105,59,13,10,71,79,59,13,10,117,115,101,32,65,110,100,114,101,105,59 };
