Question

How do I set up a new computer to run an executable I have built with Microsoft Visual Studio?

It has been a pain. First we found out that .Net had to be installed. Now I have learned that it is expecting to have all the namespace DLLs on the system.

There has got to be a better way of compiling all that is required into one package or executable for distribution.

Answer 1

To package your .NET application and all its dependencies (including required DLLs and the .NET runtime) into a single executable or easy-to-deploy package, you can use the Self-contained Deployment or Single-file Deployment features available in .NET. This will avoid the need for the target system to have .NET pre-installed or require manually copying DLLs.

Here’s how you can set it up to make your distribution process smoother:

1. Use Self-Contained Deployment

A self-contained deployment bundles your application with the .NET runtime and all necessary libraries. This allows your application to run on a machine even if .NET is not installed.

Steps to Create a Self-Contained Deployment:

1.	Open Your Project in Visual Studio.

2.	In Solution Explorer, right-click your project and select Publish.

3.	In the Pick a publish target window, choose Folder (or wherever you want to publish the output).

4.	In the Configuration settings, change the Deployment Mode to Self-contained.

5.	Choose the Target Runtime (e.g., win-x64 for 64-bit Windows).

6.	Click Finish and then Publish.

This will create a folder with all the necessary files, including the .NET runtime. You can now copy this folder to any machine and run the application without needing .NET to be pre-installed.

2. Use Single-File Deployment

A single-file deployment is an extension of self-contained deployment. It bundles everything (the application, .NET runtime, and dependencies) into a single executable. This simplifies distribution by reducing the number of files.

Steps to Create a Single-File Deployment:

1.	Right-click on the project in Visual Studio and select Publish.

2.	Choose Folder as the target for publishing.

3.	Set Deployment Mode to Self-contained.

4.	Choose the Target Runtime (e.g., win-x64).

5.	In File publish options, check Produce single file.

6.	Optionally, you can also enable Trim unused assemblies to reduce the size of the final executable.

7.	Click Publish.

This will produce a single .exe file that contains everything your app needs to run, making it extremely easy to distribute.

3. Additional Considerations: • Framework-dependent deployment: If you don’t want to bundle the .NET runtime, you can opt for this mode, but this requires the target system to have the correct version of the .NET runtime installed. • Installers: For easier deployment, you could wrap your application in an installer using tools like Inno Setup, WiX Toolset, or the built-in Visual Studio Installer Projects extension. This will automatically copy all necessary files to the target system and ensure prerequisites are installed.
4. Using .NET CLI for Packaging (Optional)

If you prefer using the command line, you can use the .NET CLI (dotnet) to publish a self-contained or single-file application.

To publish a single-file app with .NET CLI:

dotnet publish -r win-x64 -c Release /p:PublishSingleFile=true --self-contained

This will create a single .exe in the bin/Release/netX.X/win-x64/publish folder.

Summary:

•	Self-contained deployment includes the .NET runtime and all dependencies with your app, so no external dependencies are needed on the target machine.

•	Single-file deployment bundles everything into one executable, simplifying distribution.

Answer 2

as suggested the single file format solves your problem and is supported by windows and Mac (not linux).

for windows it builds a custom install and run executable. when the exe is run, it unzip's itself to a temp folder and runs the code in the temp folder. the second time it runs, it checks if the temp folder exists and skips the unzip.

for macOs its a standard app bundle, which can be copied, or run from any location.

for linux a tar file is your best option.
