Detailed Walkthrough
Let the Festivities Begin

After the Silence Has Been Broken quest, the first part of the Dark Brotherhood's biggest contract is set in motion. At Astrid's behest, travel to the courtyard of the Temple of the Divines in Solitude. Here you will find the small wedding reception you were directed to attend. Your target is the bride, Vittoria Vici. If you approach Vittoria before she addresses the reception, she will exclaim: ''"What an amazing day this has been. I hope you're enjoying the festivities. I'm... I'm just so overwhelmed. Such kindness... for me." 
You can choose one of three dialogue options in response: 
:"The Stormcloaks say hello!"
:"Oh! Well, you tell your Stormcloak friends "hello" right back at them! This is a day of healing! Legion, Stormcloaks - all are welcome here!"
:"Hail the Imperial Legion!"
:"Ha ha ha ha! Yes, yes indeed! Hail the Imperial Legion! Hail the Stormcloaks! Hail Solitude and the Eight Divines!	On this glorious day, we honor everyone! Ha ha ha ha!"
:(Remain silent)
:"Oh, no need to be shy! My day is your day! Please - eat, drink, make merry! We're all friends here!"
During the reception, she will also tell the guests: "Please, enjoy the festivities! This is a day of peace and happiness, when Imperials and Stormcloaks join together, as equals!" or "Please, enjoy yourself!" She will then stand up with her fiancé, Asgeir Snow-Shod, and enter a door to reach the balcony, where she will begin addressing her guests. Assassinate her while she speaks to earn the bonus reward. There are several ways you can choose to accomplish the goal (see this section for more details).

Strategies

There are many strategies you can use to kill Vittoria at her wedding. If you chose to speak to some of your fellow family members, they will give you advice on ways to kill her and what may happen afterwards:
If you speak to Babette, she will tell you about a loose gargoyle statue situated above the balcony: "It's no fair. I love weddings. Astrid should have given this contract to me. Instead, she's got me visiting cities, assessing security. How boring. But listen, I think I can help you. The wedding reception is outside the Temple of the Divines, right? In Solitude? If so, the bride will probably address the crowd from the balcony. It overlooks the courtyard. Well, there's an old statue there. I've seen it. Hanging right over where she'll be standing. Old means weak. Weak means it could fall. Hmmm?" If you travel to the wall above the balcony, you can push a loose gargoyle statue when Vittoria makes her address to the wedding guests. To access this balcony, enter the Temple of the Divines, then go up the stairs to the right and through the door at the end of the corridor. You can also access this balcony by going up the stairs located to the right of Castle Dour. The gargoyle is there whether you talk to Babette or not.  
If you speak to Gabriella, she will tell you: "I hope you don't mind, but I took the liberty of surveying the site of the reception. There's a small parapet, just opposite the balcony, that would prove an excellent spot for a long-range kill. I left something there for you. If you're inclined to take that approach."'' If you take the door to the northwest of the temple entrance, you will end up on a ledge located opposite the balcony where Vittoria addresses the reception. On the ledge are six arrows, an Elixir of True Shot, and the unique magical bow Firiniel's End. You can simply shoot the bride from this spot; she is easily killed with a single sneak attack from the magic bow you are given. It is best to use these free items now to be sure she is killed immediately. This is especially important if you have a low Archery skill and are planning a ranged attack. Like the gargoyle, the bow is there even if you haven't talked to Gabriella. 
Nazir will warn you about the possible outcome of murdering Vittoria: ''"Slaughtering the Emperor's cousin? At her wedding? Those guards will be out for blood. Wouldn't surprise me if the crowd jumped in too." 
Veezara will advise you to plan your escape route beforehand: "Your contract sounds simple, which means it certainly will not be. Getting into that reception will be easy, but have you thought about getting out?"''
Other strategies for killing Vittoria include the following: 
Pickpocket a Frenzy poison into the groom's inventory as Vittoria addresses the crowd. He will immediately drink it, turn, and kill her, provided that the poison is of sufficient strength. Casting a spell of Frenzy will achieve the same effect, though the Quiet Casting perk may be needed to avoid detection. To kill with a particular poison, you will need a poison of better than Weak strength and the Poisoned perk.
Another way to deal with this assassination without incurring a bounty is to turn into a werewolf or a vampire lord  (without being seen and therefore incurring no bounty), and then use the door to the overhead balcony where she is located and kill her. A good spot to transform while Vittoria is speaking is the small nook behind the loose gargoyle. By crouching (sneaking) inside this nook, you can avoid incurring a bounty for transforming, and you can swiftly jump down on the bride before the crowd notices what's happening.
A very blunt approach is to follow the happy couple to the balcony where the bride gives her speech. If you crouch down behind the couple you will not be seen by them or the guests. You can kill the bride and by killing the groom as your last witness you will get rid of the bounty and both are joined in death.
Another blunt approach involves dropping onto the balcony, crouching, and using Unrelenting Force.

You could also purchase an invisibility potion and use it when killing Vittoria, guards shouldn't know that you did it.

'Til Death Do Us Part

Once Vittoria is killed, pandemonium will break loose. Veezara will then appear, sent by Astrid to offer a distraction while you escape. Even if you weren't detected and got away with the assassination undiscovered, Veezara will still charge in and initiate combat with everyone, drawing attention away from you so you can simply walk out. Sometimes, the guests will still give chase, in which case you can escape the city quickly by using a stairwell under the Castle Dour tower bridge, near the market. One way of avoiding a bounty is to fast travel to the Sanctuary to collect your reward as soon as Vittoria is killed and before the guests turn hostile. 
Summoning a Legend of the Brotherhood
Upon your arrival back to the Sanctuary, Astrid will congratulate you on your success: ''"With Vici's murder, you've started us down a path the Dark Brotherhood hasn't traveled in centuries. The assassination of an Emperor. And now, your reward. A unique spell to summon a legend of the Dark Brotherhood. His soul serves us now in death, as his body once did in life". This spell will allow you to summon the powerful spirit of an assassin to fight by your side. If you fulfilled the bonus requirements, she will also say "Ah, and of course, a bonus, for killing Vici while she addressed her guests, as instructed. Gold... simple and pure. Spend it as you will.", and give you a leveled amount of gold. Astrid will then carry on: "Now then. Time to proceed to the next stage of the plan. Go and speak with Gabriella. She's been helping me arrange your next contract." When you approach her again, she will tell you: "As I said, go speak with Gabriella. She's been assisting me with your next contract. This Emperor business, well... it does involve everyone."'' The next quest, Breaching Security, will now begin.

Achievements
One achievement is unlocked at the end of this quest:
 

Notes
Completion of this quest will make another minor quest unavailable, unless you completed that one first.
Some of the guests at the wedding include Elisif the Fair, Alexia Vici, Vulwulf Snow-Shod, Nura Snow-Shod, Vivienne Onis, Kayd, Rorlund, Pantea Ateia, Lodi, Noster Eagle-Eye, and a Penitus Oculatus agent.
After Veezara appears, if you are not being pursued, you can talk to all of the wedding guests to hear their individual reactions to Vittoria's murder.
Even if you are not detected when killing the bride, the guests will still turn hostile, and attacking them will incur a bounty. Raising and lowering arms will count as yielding and will not earn you a bounty.
If you are a thane of Solitude, Elisif the Fair will defend you from hostiles. She will even attack her own guards.
Plautis Carvain and his wife can be found traveling in the wilderness, and claim to be heading towards the wedding, although they never appear and are not mentioned afterwards.
Plautis Carvain and Salonia Carvain may be found traveling after the quest is complete, and claim to have been robbed by bandits, and missed the wedding.
Using an Invisibility potion, power, or spell may help you avoid a bounty if it is used right after the murder, although the guards may still locate and attack you, causing the bounty to be incurred.
If Elisif is shot by you or someone else, she will equip a bow and the arrow (if usable) for the rest of the game.
Vittoria's body can be looted for her wedding dress, wedding sandals, wedding wreath, and her wedding band before it disappears. If the body is gone, you can find Vittoria's remains in the Catacombs, in a coffin on the northeastern side of the longest tunnel.
Killing Vittoria by casting a Frenzy spell at her can cause her to exit the balcony, which would cause your bonus to be forfeit as she is no longer considered "speaking to the guests".

Bugs
 
To avoid this, double back and trigger Veezara before escaping the town
 
 
 This bug can be fixed by entering   in the console after killing the target.
 
The body can actually be looted between the lower levels seats where they sit before going up to the balcony. It can't be seen, but is still lootable.
 
 
Reloading the game may fix this.
