Creating a C# Project for Extensions

This article explains how to create an empty C# project for Beutl extensions.

This guide introduces the methods using Visual Studio Code or Visual Studio. The target Beutl version is 1.1.0.

Visual Studio Code​

  1. Use the terminal to create a class library.
dotnet new classlib -o MyBeutlExtension

Ensure the directory structure is as follows:

MyBeutlExtension
┣━ obj
┃  ┗━ (...)
┣━ Class1.cs
┗━ MyBeutlExtension.csproj
  1. Edit the generated MyBeutlExtension.csproj as follows:
<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <!-- Change the TargetFramework according to the Beutl version -->
    <TargetFramework>net10.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>

    <!-- The following are optional. -->
    <RepositoryUrl>url/to/repository</RepositoryUrl>
    <PackageId>MyBeutlExtension</PackageId>
    <Title>Sample Extension</Title>
    <Description>Sample</Description>
    <PackageTags>sample</PackageTags>
    <Version>1.0.0</Version>
    <AssemblyVersion>1.0.0.0</AssemblyVersion>
    <Authors>Author Name</Authors>
  </PropertyGroup>

  <!-- Ensure the build is recognized as a sideload extension. -->
  <PropertyGroup Condition="'$(Configuration)'=='Debug'">
    <AppendTargetFrameworkToOutputPath>false</AppendTargetFrameworkToOutputPath>
    <AppendRuntimeIdentifierToOutputPath>false</AppendRuntimeIdentifierToOutputPath>
    <EnableDynamicLoading>true</EnableDynamicLoading>
    <OutputPath>$([System.Environment]::GetFolderPath(SpecialFolder.UserProfile))\.beutl\sideloads\$(AssemblyName)</OutputPath>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Beutl.Extensibility" Version="1.1.0" />
    <PackageReference Include="Beutl.ProjectSystem" Version="1.1.0" />
    <PackageReference Include="Beutl.Operators" Version="1.1.0" />
  </ItemGroup>

</Project>
  1. Run the following commands to generate nuget.config and add the package source.
dotnet new nugetconfig
dotnet nuget add source "https://nuget.beditor.net/v3/index.json" --name nuget.beditor.net

This completes the creation of an empty C# project for extensions.

Visual Studio​

  1. Open Visual Studio and click File > New > Project.
    Create Visual Studio Project

  2. Select Class Library and click Next.
    Select Class Library

  3. Enter the project name and location, then click Next. Confirm Name and Location

  4. Select the framework according to the Beutl version.

  5. Click Create.

Ensure the directory structure is as follows:

MyBeutlExtension
┣━ MyBeutlExtension
┃  ┣━ obj
┃  ┃  ┗━ (...)
┃  ┣━ Class1.cs
┃  ┗━ MyBeutlExtension.csproj
┗━ MyBeutlExtension.sln
  1. Edit the generated MyBeutlExtension.csproj as follows:
<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <!-- Change the TargetFramework according to the Beutl version -->
    <TargetFramework>net10.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>

    <!-- The following are optional. -->
    <RepositoryUrl>url/to/repository</RepositoryUrl>
    <PackageId>MyBeutlExtension</PackageId>
    <Title>Sample Extension</Title>
    <Description>Sample</Description>
    <PackageTags>sample</PackageTags>
    <Version>1.0.0</Version>
    <AssemblyVersion>1.0.0.0</AssemblyVersion>
    <Authors>Author Name</Authors>
  </PropertyGroup>

  <!-- Ensure the build is recognized as a sideload extension. -->
  <PropertyGroup Condition="'$(Configuration)'=='Debug'">
    <AppendTargetFrameworkToOutputPath>false</AppendTargetFrameworkToOutputPath>
    <AppendRuntimeIdentifierToOutputPath>false</AppendRuntimeIdentifierToOutputPath>
    <EnableDynamicLoading>true</EnableDynamicLoading>
    <OutputPath>$([System.Environment]::GetFolderPath(SpecialFolder.UserProfile))\.beutl\sideloads\$(AssemblyName)</OutputPath>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Beutl.Extensibility" Version="1.1.0" />
    <PackageReference Include="Beutl.ProjectSystem" Version="1.1.0" />
    <PackageReference Include="Beutl.Operators" Version="1.1.0" />
  </ItemGroup>

</Project>
  1. Run the following commands to generate nuget.config and add the package source.
dotnet new nugetconfig
dotnet nuget add source "https://nuget.beditor.net/v3/index.json" --name nuget.beditor.net
  1. Click Restore NuGet Packages to ensure that NuGet dependencies are restored correctly.
    Restore NuGet Packages

This completes the creation of an empty C# project for extensions.
