in the watch window or quickwatch:
"$exception": the current exception that is currently available. it has a much better debug experience in the quickwatch because it can look into the exception's type
"{num}#": eg "1#". this is a reference to an object with ObjectId. it acts as a weak-reference and does not affect the GC'ability of the object. http://blogs.msdn.com/b/zainnab/archive/2010/03/04/make-objectid-vstipdebug0015.aspx
"$ReturnValue": contains the return value from the last exited method. The autos-window contains a much better display of that. http://blogs.msdn.com/b/visualstudioalm/archive/2013/06/27/seeing-function-return-values-in-the-debugger-in-visual-studio-2013.aspx
"$user": displays the information about the current user - eg to check for permissions, impersonations, etc
"{number-variable},h": displays the variable as hex
"{number-variable},d": displays the variable as decimal/number

List<Task> tasks = new List<Task>();

for (int i = 1; i <= 1000; i++) {
  var reqT = new HttpClient().GetAsync("http://www.youtube.com/playlist?list=MCUS.." + i);
    
	reqT.ContinueWith(t => {
		var req = t.Result;
		
		if (req.IsSuccessStatusCode) {
			var title = Regex.Match(req.Content.ReadAsStringAsync().Result, "(<title>).*(</title>)").ToString().Replace("<title>", string.Empty).Replace("</title>", string.Empty);

Windows

On windows you can specify file repositories with file:///\\<computer>\<path> (ex: file:///\\homepc\repos\git-backup.git).

It is always a good practice to postfix the folder with .git to indicate that this folder is a bare repository.

#Model 

@user.should have(1).error_on(:username) # Checks whether there is an error in username 
@user.errors[:username].should include("can't be blank")  # check for the error message 

#Rendering
response.should render_template(:index)

#Redirecting 
response.should redirect_to(movies_path)
