I created a new WinForms project and got this error:
The designer could not be shown for this file because none of the classes within it can be designed.
I have not yet added any code to the project. It appears as if all of the necessary assemblies are referenced, but intellisense can't seem to resolve the Form class.
Shutting VS2012 down and starting it back up again solved the issue. Weird.

Maybe the fact that I mentioned WPF when the OP was looking for ASP.NET was the reason. I don't see how my answer was wrong in that context as you could esily substitute the WPF front end with a ASP.NET version (or have both, and....).

If the topic isn't something you are interested in, or have knowledge of, then you will give up on it and that won't help you. Find something that interests you and use that as a basis of your project.

First of all this is wrong place to ask this question. Such question could be asked in GIT or Lounge.
Secondly, I appreciate the intention that you have behind posting this question i.e. learning but perhaps(like others said) you should be able to come up with some ideas on your own.
thirdly, my suggestion would be to start small application like contact book/address book or small forums. but keep in mind that your sole focus should be on learning various concepts related to C# and ASP.NET than just getting your project done.

I am trying to convert the string to datetime including the milliseconds... unfortunately when I used the Convert.ToDateTime method, it does not return the milliseconds... I have tried the parse and parseExact method in the Datetime and DateTimeOffset classes as well... none of them returning the milliseconds... I read the previous discussion regarding this issue and none of the solutions return the milliseconds...This is what I am trying to do:
Thank you so much for taking your time to respond to my post... I really appreciate it... but the solution both of you mentioned does not work for my situation... may be I did not state my question clearly... I apologize for that...
Pete, in your solution, you are converting the date to string again... that's not what i want...
And BMS121, I used the 'TimeOfDay' property as you suggested , but I could not assign that to datetime variable... I get compiler error :'Cannot implicitly convert System.TimeSpan to System.Datetime...
This is what I want to accomplish:
I am getting the datetime as a string from client ... so I have to convert that string to datetime including millisecond and then I have to store/save that datetime in the database (the datebase column is datetime type)...
Here is the code snippet:
string strDate = "2012-11-09 07:20:07.410"
Datetime actualDate = Convert.ToDateTime(strDate); -(L2)
L2 : does not return millisecond...
As per BMS121 suggestion, I tried the following :
(my entity object is called EDEntitiy)
Edentity.Timestamp = actualDate.TimeOfDay;
But above statement causes compiler error:
'Cannot implicitly convert System.TimeSpan to System.Datetime...
You are misunderstanding Pete's solution. Convert.ToDateTime is already giving you the right answer, but the default ToString on a DateTime omits the milliseconds, so it looks like it isn't when you look at the string representation of the DateTime you create. If you format it with milliseconds, you'll see that you got what you expected.
Thanks. Really appreciate it. My issue is this.
string strDate = "2012-11-09 07:20:07.410"
Datetime actualDate = Convert.ToDateTime(strDate);
Now when I save this date (actualDate) in the database(I am using the Entity Frame work to connect to the database), this is what i see in the database : 2012-11-09 07:20:07.000
As you can see, the millisecond is zero in the database... so my question is how do I save date (after converting from string to datetime) with milliseconds... my datebase date column is SQL datetime type...
