How To Merge Branches in Git Extensions

In this example, consider the following.

ViewDefaultDateRange - Main branch in my GIT repository
ProvisioningEnhancement - Sub-branch

What I need is to merge "ProvisioningEnhancement" branch into my main branch "ViewDefaultDateRange"

Go to Commands => Merge branches

Then from the Pop-Up window select "ProvisioningEnhancement" branch in the Merge with dropdown and click Merge.

If successfully merged, you will see a success message. Something like below;

Now you have successfully merged the two branches.

Cheers!
