This tutorial shows how to set up a Docker container in a .NET 6 Console application using the LEADTOOLS SDK. Overview Summary This tutorial covers how to Containerize a .NET 6 Console Application using LEADTOOLS with Docker. Completion Time 30 minutes Platform .NET 6 Console Application using Docker IDE Visual Studio 2022 Development License Download LEADTOOLSRequired KnowledgeBefore working on the Containerize .NET 6 Applications with Docker - C# .NET 6 tutorial, ensure that you install the LEADTOOLS SDK as well as Docker for Desktop. If you do not have both downloaded, use the below links to access the respective installers.Docker DesktopDownload LEADTOOLSPrepare Project for use with DockerLocate the .NET 6 Console project you wish to work with.Many of these projects can be found in the functionality file folders in: C:\LEADTOOLS23\Examples\\DotNetOnce you have the .NET 6 project you wish to use, rename the project's folder structure to \App\. Ensure that you move all the files and folders needed for the project into the App directory where the .csproj is located.Next in the App folder create a new folder called data, which will contain any external resources needed by the application (i.e. images loaded by the application). Edit your code where it is loading files from local paths and modify it to look into the data folder like so, /App/data/, where is the name of the file you are loading. Ensure the entire project is self contained outside of web resources.If you are setting your LEADTOOLS license, create a new folder called license inside the App\data directory and place your LEADTOOLS.LIC and LEADTOOLS.LIC.key files there. Edit your code to have the application look to the following file paths to load your license files:/App/data/license/LEADTOOLS.LIC/App/data/license/LEADTOOLS.LIC.keyCreating the DockerfileNavigate to the folder that contains the App directory. Create a new file named Dockerfile. This file will contain all the instructions for Docker to build the container. The Dockerfile instructs Docker to install the required dependencies within the container.Setup Project FilesThis section of the Dockerfile will set up the project files to be run in the container. First, it installs the SDK required by the application (change to match accordingly, information found at hub.docker.com/_microsoft-dotnet-sdk).Next, it sets the container's current directory to /app and copies all .csproj files in the local App directory to the container's app directory and restores the project.It copies all the necessary files in the local App and App/data directories to the container's app and /app/out/data directories. Finally, it publishes a release version of the project to the container's app/out directory.Add the following code to the Dockerfile:### Building the project FROM mcr.microsoft.com/dotnet/sdk:6.0 WORKDIR /app # Copy CSPROJ and restore COPY ./App/*.csproj . RUN dotnet restore # Copy everything else and build COPY ./App/* . COPY ./App/data ./out/data RUN dotnet publish -c Release -o ./out/ Setup Runtime EnvironmentThis next section of the Dockerfile will set up the runtime environment in the container.First, it installs the runtime required by the application (change to match accordingly, information found at hub.docker.com/_microsoft-dotnet-sdk). Next, it sets a container environment DEBIAN_FRONTEND. Installing the homebrew-cask dotnet will conflict with the dotnet-sdk, so to get both the runtime, and the sdk install dotnet-sdk. brew cask install dotnet-sdk In short, the runtime will allowcan dotnet framework 4.6.1 run on Linux dotnet-sdk? : r/dotnet

This is used by the .NET SDK to help tools that run during .NET SDK commands ensure they use the same dotnet runtime for any child dotnet processes they create for the duration of the command. Tools and MSBuild Tasks within the SDK that invoke binaries via the dotnet host are expected to honor this environment variable to ensure a consistent experience.Tools that invoke dotnet during an SDK command should use the following algorithm to locate it:if DOTNET_HOST_PATH is set, use that value directlyotherwise, rely on dotnet via the system's PATHNoteDOTNET_HOST_PATH is not a general solution for locating the dotnet host. It is only intended to be used by tools that are invoked by the .NET SDK.DOTNET_LAUNCH_PROFILEThe dotnet run command sets this variable to the selected launch profile.Given the following launchSettings.json file:{ "profiles": { "First": { "commandName": "Project", }, "Second": { "commandName": "Project", } }}And the following Program.cs file:var value = Environment.GetEnvironmentVariable("DOTNET_LAUNCH_PROFILE");Console.WriteLine($"DOTNET_LAUNCH_PROFILE={value}");The following scenarios produce the output shown:Launch profile specified and exists$ dotnet run --launch-profile FirstDOTNET_LAUNCH_PROFILE=FirstLaunch profile not specified, first one selected$ dotnet runDOTNET_LAUNCH_PROFILE=FirstLaunch profile specified but does not exist$ dotnet run --launch-profile ThirdThe launch profile "Third" could not be applied.A launch profile with the name 'Third' doesn't exist.DOTNET_LAUNCH_PROFILE=Launch with no profile$ dotnet run --no-launch-profileDOTNET_LAUNCH_PROFILE=NUGET_PACKAGESThe global packages folder. If not set, it defaults to ~/.nuget/packages on Unix or %userprofile%\.nuget\packages on Windows.DOTNET_SERVICINGSpecifies the location of the servicing index to use by the shared host when loading the runtime.DOTNET_NOLOGOSpecifies whether .NET welcome and telemetry messages are displayed on the first run. Set to true to mute these messages (values true, 1, or yes accepted) or set to false to allow them (values
2025-04-208 ランタイムをインストールした場合、8.0.2 ASP.NET Core ランタイムと 8.0.8 .NET ランタイムがインストールされます。 それぞれにバージョン管理されたディレクトリがあります。 詳細については、「.NET のバージョン管理の方法の概要」を参照してください。.NET を手動でインストールすると、通常は /usr/local/share/dotnet/ または $HOME/.dotnet ディレクトリにインストールされます。 SDK、ランタイム、および .NET ホストは、個別のサブディレクトリにインストールされます。 これらの "コンポーネント" ディレクトリには、.NET の各バージョンのディレクトリが含まれています。 バージョン管理されたディレクトリを削除すると、そのバージョンの .NET がシステムから削除されます。 これらのディレクトリは、お使いの macOS のバージョンでは異なる場合があります。.NET がインストールされている場所を検出するために使用できるコマンドは 3 つあります。SDK の場合は dotnet --list-sdks、ランタイムの場合は dotnet --list-runtimes、すべての場合は dotnet --info です。 これらのコマンドでは、.NET ホストは一覧表示されません。 インストールされているホストを確認するには、/usr/local/share/dotnet/host/fxr/ ディレクトリをチェックします。 次の一覧は、.NET の特定のバージョンのディレクトリを表します。ここで、$version 変数は .NET のバージョンを表します。SDK:/usr/local/share/dotnet/sdk/$version/ランタイム:ランタイムは、Microsoft.AspNetCore.All や Microsoft.NETCore.App (具体的には .NET ランタイム) などの特定の .NET 製品ランタイムに基づいています。 これらは /usr/local/share/dotnet/shared/$product/$version ディレクトリにインストールされます。ここで、$product は製品ランタイムです。 たとえば、次のディレクトリが表示される場合があります。/usr/local/share/dotnet/shared/Microsoft.NETCore.App/$version/dotnet --info/usr/local/share/dotnet/shared/Microsoft.AspNetCore.App/$version//usr/local/share/dotnet/shared/Microsoft.AspNetCore.All/$version/.NET ホスト/usr/local/share/dotnet/host/fxr/$version/rm -rf コマンドを使用して .NET のバージョンを削除します。 たとえば、6.0.406 SDK を削除するには、次のコマンドを実行します。sudo rm -rf /usr/local/share/dotnet/sdk/6.0.406重要バージョン ディレクトリは、アンインストールしている "バージョン" と一致しない場合があります。 1 つの .NET リリースと共にインストールされる個々のランタイムと SDK は、バージョンが異なる場合があります。 たとえば、ASP.NET Core 8 ランタイムをインストールした場合、8.0.2 ASP.NET Core ランタイムと 8.0.8 .NET ランタイムがインストールされます。 それぞれにバージョン管理されたディレクトリがあります。 詳細については、「.NET のバージョン管理の方法の概要」を参照してください。.NET アンインストール ツールを使用すると、.NET SDK とランタイムをシステムから削除できます。 一連のオプションを使用して、アンインストールするバージョンを指定できます。 詳細については、.NET アンインストール ツールの概要に関するページを参照してください。NuGet フォールバック ディレクトリを削除する.NET Core 3.0 SDK より前では、.NET Core SDK インストーラーでは NuGetFallbackFolder という名前のディレクトリを使用して NuGet パッケージのキャッシュを保存していました。 このキャッシュは、dotnet restore や dotnet build /t:Restore などの操作中に使用されました。 NuGetFallbackFolder は、.NET がインストールされている sdk フォルダーの下にあります。 たとえば、Windows では C:\Program Files\dotnet\sdk\NuGetFallbackFolder に、macOS では /usr/local/share/dotnet/sdk/NuGetFallbackFolder にある可能性があります。次の場合は、このディレクトリを削除することができます。.NET Core 3.0 SDK または .NET 5 以降のバージョンのみを使用して開発している。3\.0 より前の .NET Core SDK のバージョンを使用して開発しているが、オンラインで作業できる。NuGet フォールバック ディレクトリを削除したい場合は削除できますが、管理者特権が必要です。dotnet ディレクトリの削除はお勧めしません。 これを行うと、以前にインストールしたグローバル ツールがすべて削除されます。 また、Windows の場合は、次のことが発生します。Visual Studio 2019 バージョン 16.3 以降のバージョンが破損します。 [修復] を実行して回復できます。[アプリと機能] ダイアログに .NET Core SDK エントリがある場合、それらは孤立状態になります。 --> GitHub で Microsoft と共同作業する このコンテンツのソースは GitHub にあります。そこで、issue や pull request を作成および確認することもできます。 詳細については、共同作成者ガイドを参照してください。 その他のリソース この記事の内容
