NOTE The keyword here is "default". I know I can hit escape and the default behavior gets aborted. I don't want to hit the escape key every time the IDE thinks it knows what I want. I didn't have to do this in 2013.
ADDENDUM 2 It seems I'm still having difficulty communicating what I'm after here. What I want to happen is nothing when I press the space bar... I just want a space character to show up on my screen. The only time I want the IDE to actually insert a suggestion is when I hit the tab bar. I hope that's clearer?
This is driving me nuts. 2013 and before allowed you to set completion characters (maybe that was resharper?) but in 2015 I see no way to stop the default behavior of autocomplete.
For example, say I have a class Foo, but I don't have the namespace specified already, yet I have a class FooBar in one of the specified namespaces, if I type:
public void DoSomething(Foo// <-- then a space)
...it automatically puts FooBar. How the heck do I turn off this behavior?
I should mention that I still want AutoComplete, just on tab though.

Edit -> Intellisense -> Toggle Completion Mode
From : https://msdn.microsoft.com/en-us/library/hcw1s69b.aspx
"You can also change to suggestion mode, in which only the text you type is inserted into the code. For example, if you enter an identifier that is not in the list and press TAB, in completion mode the entry would replace the typed identifier. To toggle between completion mode and suggestion mode, press CTRL+ALT+SPACEBAR or click Edit/IntelliSense/Toggle Completion Mode."

For all who have the same problem in Visual Studio Code, add this line to the User Settings:
"editor.acceptSuggestionOnCommitCharacter": false
回答3:
change the setting for Editor: Accept Suggestion On Enter to off

I just did this in Visual Studio by going to:
File > Preferences > Settings > toggle "Suggest on Trigger Characters"
I also toggled off "Auto Suggestion on Commit Character" and "Accept Suggestion on Enter" - however you may want those settings.

If you use Vs2017 and the setting resets everytime you launch Vs, i created a small script that automatically disables space completion at launch using Visual Commander Extension:

If you're using Resharper and Visual studio 2017, you may need to use a combination of the existing answers to stop getting the autocomplete behaviour when pressing space. This is too long for a comment so added an answer.
Make sure in Visual studio that intellisense Toggle Complete Mode is off/unselected (as noted in other answers). Note: If you turn on the "Text editor" icons in the VS toolbar at the top, you'll see an extra icon that gets highlighted on and off showing you whether intellisense is toggled on or off. AND
In the resharper dropdown on the toolbar (Resharper > Options...), Go to IntelliSense > Completing Charactes > and then uncheck the "Complete on space" box for C#.
Now autocomplete doesn't occur when pressing space (can still use tab, etc to autocomplete).
(Related aside: This autocomplete on space is really bad if you use VSVim, because you can't by default use the typically vim ESC key to 'get out' of the autocomplete mode. e.g. it's very difficult to even type in the static modifier for a variable/function without it changing to some other autocomplete choice.)
