If you just want to try it out to see how it works, this step shows you how to set up a sample. NET Windows Forms project to use. Name the project WinformsTest. Configure the project to use. Open a terminal and navigate to the folder where the target project or solution is located.
Run the upgrade-assistant command, passing in the name of the project you're targeting you can run the command from anywhere, as long as the path to the project file is valid. As each step is completed, the tool provides a set of commands allowing the user to apply or skip the next step, see more details, configure logging, or exit the process. If the tool detects that a step will perform no actions, it automatically skips that step and continues to the next step until it reaches one that has actions to do.
Pressing Enter will start the next step if no other selection is made. The tool prompts for a custom path for the backup, or to use the default, which will place the project backup in the same folder with a. The next step the tool does is to convert the project file to SDK style. Once the packages are updated, the next step is to add template files, if any.
In this case, there are no template files that need to be added. This step continues and migrates app config files and updates C source to apply fixes, as shown below. This project didn't need any config file or source code changes, so these steps proceeded automatically. Net framework version will be your choice? My current choice is.
Net 2. Winforms has been feature-complete since. NET 2. The team that worked on it exists in name only, most of the team members switched to WPF. Only critical operating system compatibility and security fixes have been released since 2. I'm only aware of a change in SendKeys to make it work better in Vista. Designer error handling was improved in VS Some late additions that are not technically part of Winforms nor are included with the framework download but otherwise work well in a Winforms app are the Visual Basic Power Pack controls, the Chart control and the Windows API Code Pack.
Since the introduction of WPF in. NET 3. So if you choose. NET 2, there won't be a big problem. However, noticed that Microsoft no longer supports. NET 2 alone you must use. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
Create a free Team What is Teams? Don't rely on tools such as the. NET Portability Analyzer to back up your project, even if they seem to. It's best to personally create a copy of the original project. If your project is referencing NuGet packages, you probably have a packages. Visual Studio project files can optionally define NuGet packages in the project file too. NET 5 doesn't use packages. NuGet package references must be migrated into the project file before migration.
The next step in migrating your app is converting the project file. As previously stated,. NET Framework uses. However, there's the possibility that you're already using SDK-style projects. You can easily spot the difference in Visual Studio. Right-click on the project file in Solution explorer and look for the Edit Project File menu option.
If this menu item is missing, you're using the old Visual Studio project format and need to upgrade. Convert each project in your solution. If you're using the sample app previously referenced, both the MatchingGame and MatchingGame. Logic projects would be converted. Copy-and-paste the project XML into a text editor. You'll want a copy so that it's easy to move content into the new project.
Remove that entry if you're upgrading a library project. This XML gives you the basic structure of the project. However, it doesn't contain any of the settings from the old project file. Using the old project information you previously copied to a text editor, do the following steps:.
One thing to note about the difference between. NET 5 is that. NET Framework projects use an opt-in model for code files. Any code file you want to compile needs to be explicitly defined in your project file. SDK-style projects are reverse, they default to opt-out behavior: All code files starting from the project's directory and below are automatically included in your project.
You don't need to migrate these entries if they are simple and without settings. This is the same for other common files such as resx. The app. Visual Basic projects typically use the folder My Project while C projects typically use the folder Properties for the default project settings file.
Visual Basic projects typically use the folder My Project while C projects typically use the folder Properties for the default project resource file. This setting imports the My namespace members Visual Basic programmers are familiar with. Visual Basic projects can automatically import namespaces into every code file. If the project fails to load, you may have introduced a mistake in the XML of the project. Open the project file for editing and try to identify and fix the mistake.
