Best Way to Deploy Visual Studio Application That Can Run Without Installing

Best way to deploy Visual Studio application that can run without installing

It is possible and is deceptively easy:

1. "Publish" the application (to, say, some folder on drive C), either from menu Build or from the project's properties → Publish. This will create an installer for a ClickOnce application.
2. But instead of using the produced installer, find the produced files (the EXE file and the .config, .manifest, and .application files, along with any DLL files, etc.) - they are all in the same folder and typically in the bin\Debug folder below the project file (.csproj).
3. Zip that folder (leave out any *.vhost.* files and the app.publish folder (they are not needed), and the .pdb files unless you foresee debugging directly on your user's system (for example, by remote control)), and provide it to the users.

An added advantage is that, as a ClickOnce application, it does not require administrative privileges to run (if your application follows the normal guidelines for which folders to use for application data, etc.).

As for .NET, you can check for the minimum required version of .NET being installed (or at all) in the application (most users will already have it installed) and present a dialog with a link to the download page on the Microsoft website (or point to one of your pages that could redirect to the Microsoft page - this makes it more robust if the Microsoft URL change). As it is a small utility, you could target .NET 2.0 to reduce a user's probability to install .NET.

It works. We use this method during development and test to avoid constantly uninstalling and installing the application and still being quite close to how the final application will run.

publish winforms application without install

Go to your solution and set the CopyLocal to true for all projects, this will ensure that the ..\Bin folder contains all the necessary assemblies for your program. Then just zip up the ..\Bin folder, get it onto the client machine, and then unzip it.

Hope this helps!

Create Desktop(window) application that can run without installing?

There is nothing in Windows that requires an application to be installed. That said, installation is intended to:

• Make things more simple for the end user.
• Setup the registry, usually for path information and uninstall information.
• Initialize any initial information the software may need before it's first run.

Simply avoiding using the registry and saving files locally to your application is usually enough to make your application portable.

That said, as long as you allow the user to select a database location within your software, you should be fine. Saving the information on the pen-drive, in an .ini file for instance, would allow each computer you plug into to read these same settings.

If you expect each computer to have a difference connection string to the database, you could save your settings to the %appdata% directory. When the user plugs the pendrive back in later, his settings will still be there, and no other user will see these same settings.

The downside to the second approach, however, is that the user has no way to "uninstall" and recover the space written to %appdata% automatically. However, for most private business applications, this isn't much of a concern.

Edit: If your real question here is how to distribute an application without an installer, simply build the Release version of your application, and look in /bin/Release/ within your project. Copy these files to another location, remove any debug or unneeded files, and make sure you have all your dependencies in order.

Can I Create C# Standalone Application Than Runs Without Installing in Windows?

How about instead of publishing it just copy the .exe from the bin/debug folder? Then it should work without installing or publishing it. (if it is just 1 Assembly)

VB.net app without installation

If they have the .NET Framework installed (the version of it that you developed it), they only need the .exe. You can find the .exe file in the bin directory of your projects folder in your Visual Studio workspace.

If they do not have the framework installed, you'll need to produce an installation for them. It's extremely easy with Visual Studio by just creating a setup project in the same solution as your code.

How to run a .net app without installing .net?

If you have developed app using .NET Core 3.1+, then Publish self-contained app.

Example: To publish Windows 64-bit executable - dotnet publish -r win-x64

Note - To build and publish, of course, you would need .NET SDK. But once you have published a self-contained app and obtained the executable:

The user of your app isn't required to download and install .NET Core.

Release Windows Forms project without an installer

You must send the EXE file and any DLL file that you reference locally. If you use COM references and the like, you need to register them during the installation. The same thing for the GAC I think, but I haven't used that for stand-alone applications myself.

The application.exe.config file contains the application settings (a copy of app.config). If you don't use settings or the user doesn't typically care about them, you can omit the file, and it will use the default values you built the application with.

The vshost files are not needed (if you have them). They are used by Visual Studio's debugger. The .pdb files contain debug data used to facilitate DLL file to source matching. Unless you plan on attaching a debugger to the application, there is no point sending those.

how to make project without .Net?

You can publish an application with self-contained enabled. This will build an application that includes all the dotnet framework files needed to run the application.

This does make the application bigger, even the most basic dotnet6 console app on my machines is ~10mb and when it's framework dependent it's 160kb

the settings used in the UI:

You can do this in console with:

dotnet publish -r win-x86 -c Release --self-contained true -p:PublishTrimmed=true -p:PublishSingleFile=true
