Embed resources to file

This is how you can use ThisAssembly_Resources .

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>
	<ItemGroup>
		<EmbeddedResource Include="Content/mytext.sql" />
	</ItemGroup>
	<ItemGroup>
	  <PackageReference Include="ThisAssembly.Resources" Version="1.4.1">
	    <PrivateAssets>all</PrivateAssets>
	    <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
	  </PackageReference>
	</ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
</Project>

The code that you will use is

Console.WriteLine(ThisAssembly.Resources.Content.mytext.Text);

This is from file
