RSCG – QueryStringGenerator
 
 

Generate from string properties of a class a query string for a URL.

This is how you can use QueryStringGenerator .

The code that you start with is

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net9.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="QueryStringGenerator" Version="1.1.0">
      <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

using DemoQuery;
Person p = new();
p.FirstName = "Andrei";
p.LastName = "Ignat";
p.Age = 55;
Console.WriteLine(p.ToQueryString());

using QueryStringGenerator;
namespace DemoQuery;
[QueryString]
internal class Person
{
    public string FirstName { get; set; }=string.Empty;
    public int Age {  get; set; }
    public string LastName { get; set; } = string.Empty;

}

The code that is generated is

// <auto-generated />

namespace DemoQuery
{
    [System.CodeDom.Compiler.GeneratedCodeAttribute("QueryStringGenerator", "1.0.0")]
    internal static class QueryStringExtensionForPerson
    {
        public static string ToQueryString(this Person _this)
        {
            if (_this == null)
            {
                return string.Empty;
            }

            var sb = new System.Text.StringBuilder();

            if (_this.FirstName != null)
            {
                sb.Append($"&firstname={System.Net.WebUtility.UrlEncode(_this.FirstName)}");
            }

            if (_this.LastName != null)
            {
                sb.Append($"&lastname={System.Net.WebUtility.UrlEncode(_this.LastName)}");
            }

            return sb.ToString();
        }
    }
}

// <auto-generated />

namespace QueryStringGenerator
{
    [System.CodeDom.Compiler.GeneratedCodeAttribute("QueryStringGenerator", "1.0.0")]
    internal class QueryStringAttribute : System.Attribute
    {
        public string MethodName { get; set; }

        public QueryStringAttribute(string methodName = "ToQueryString")
        {
            MethodName = methodName;
        }
    }
}

RSCG – GenPack
 
 

Generating Binary Serialization and properties for class

This is how you can use GenPack .

The code that you start with is

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net9.0</TargetFramework>

	</ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
</Project>

The code that you will use is

using SerializerDemo;

var p= new Person() { Name= "Andrei Ignat" };
var bytes= p.ToPacket();
var entity = Person.FromPacket(bytes);
Console.WriteLine("name is "+entity.Name);

using GenPack;

namespace SerializerDemo;

           .@short("Id", "Age description")
           .@string("Name", "Name description")
           .Build();
}

The code that is generated is

RSCG – RazorSlices
 
 

Generating html from razor templates. Attention: generates IHttpResult, not html string.

This is how you can use RazorSlices .

The code that you start with is

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

  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.OpenApi" Version="8.0.10" />
    <PackageReference Include="RazorSlices" Version="0.8.1" />
    <PackageReference Include="Swashbuckle.AspNetCore" Version="6.6.2" />
  </ItemGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
</Project>

The code that you will use is

using RazorDemoSlices;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

var app = builder.Build();

// Configure the HTTP request pipeline.
//if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

var summaries = new[]
{
    "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
};
app.MapGet("/hello", (string firstName,string lastName) 
    => Results.Extensions.RazorSlice<RazorDemoSlices.Slices.PersonHTML, Person>(

        ))
        .ToArray();
    return forecast;
})
.WithName("GetWeatherForecast")
.WithOpenApi();

app.Run();

Creating typed Signal R clients

This is how you can use TypedSignalR.Client .

The code that you start with is

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>

	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>
	
</Project>

The code that you will use is

// See https://aka.ms/new-console-template for more information
using Microsoft.AspNetCore.SignalR.Client;
using TestSignalRCommon;
using TestSignalRConsole;

Console.WriteLine("Hello, World!");
await Task.Delay(5_000);

    .WithUrl("https://localhost:7302/ChatHub")
    .Build();
await _connection.StartAsync();

_connection.On<string, string>("ReceiveMessage", (user, message) =>
{
    Console.WriteLine($" from not typed {user}: {message}");
});

await Task.Delay(30_000);
