Hi William Thompson,

Thank you for reaching out to Microsoft Q & A forum. 

To connect an existing Visual Studio 2022 project to a GitHub repository, follow these steps: 

1.Ensure Git is Installed in Visual Studio 2022 

Visual Studio includes Git by default. If it's not already configured, navigate to Tools > Options > Source Control > Plug-in Selection and choose Git from the available options. 

2.Open Your Project in Visual Studio 

Launch Visual Studio 2022 and open the project you want to connect to GitHub. 

3.Sign In to Your GitHub Account 

Go to View > GitHub (or Team Explorer, depending on your setup). 

In the Team Explorer window, select Connect and sign in to your GitHub account if you haven't already. 

4.Configure the Remote URL for Your GitHub Repository 

Open Team Explorer by selecting View > Team Explorer. 

In the Branches section, right-click your main branch (usually main or master) and select Manage Branches. 

In the Git Changes window, click the Settings icon. 

In Repository Settings, under the Remotes section, click Add. 

Enter the remote name (commonly origin for the primary remote) and paste your GitHub repository’s URL, which you can find by clicking the Code button in GitHub and copying the HTTPS URL. 

5.Push Your Project to GitHub 

After setting the remote URL, navigate to View > Git Changes. You should now see that your project is linked to your GitHub repository. 

Commit any changes by clicking Commit All, add a commit message, and then press Push to upload your local changes to GitHub. 

6.Confirm Your Project on GitHub 

Visit your GitHub repository in a browser to confirm the project files have been successfully uploaded. You should also see your commit history reflected.

Thank you. 

Here are the detailed steps needed to achieve this.

The existing commands can be simply run via the CLI terminal of VS-CODE. It is understood that Git is installed in the system, configured with desired username and email Id.

1. Navigate to the local project directory and create a local git repository:

   git init

2. Once that is successful, click on the 'Source Control' icon on the left navbar in VS-Code.One should be able to see files ready to be commit-ed. Press on 'Commit' button, provide comments, stage the changes and commit the files. Alternatively you can run from CLI

   git commit -am "Your comment"

3. Now you need to visit your GitHub account and create a new Repository. Exclude creating 'README.md', '.gitIgnore' files. Also do not add any License to the repo. Sometimes these settings cause issue while pushing in.

4. Copy the link to this newly created GitHub Repository.

5. Come back to the terminal in VS-CODE and type these commands in succession:

   git remote add origin <Link to GitHub Repo> //maps the remote repo link to local git repo

   git remote -v //this is to verify the link to the remote repo

   git push -u origin master // pushes the commit-ed changes into the remote repo

Note: If it is the first time the local git account is trying to connect to GitHub, you may be required to enter credentials to GitHub in a separate window.

6. You can see the success message in the Terminal. You can also verify by refreshing the GitHub repo online.
