visual studio - VS2008 targeting .NET 2.0 doesn't stop me from using C# 3 features -

-

I had a VS2005 solution and wanted to get VS 2005 for the new year. I was mostly happy with the upgrade process and it was pleasantly surprised to see that my build script works primarily still.

My question is around multi-targeting feature - .NET 3.5 is not installed on my server., So I have to continue targeting the Net 2.0. It has worked, mostly, but I came to know that I can do things like

var returnMe = "result:" + result.ToString ();

... and still debug this project successfully

When I got that server up to the build server, the build failed, saying "var" "Was not defined.

So, what should I expect?

  • VS2008, targeting .NET 2.0, when I try to do things in C # 3 then errors must be thrown
  • build server, I know that I I am targeting .NET 2.0, I should understand that I am doing this and compiling it in a 2.0-compatible binary

    • Any ideas?

    The problem is that the build server does not have the right compiler You can make it on your workstation, okay?

    Many .NET 3.0 "FEATURES" are just syntax bits that come back to the CLR2 code in a timely manner. var is one of them - when it is compiled, the compiler converts var to the appropriate type.

    There is a beautiful informative post on it

    oracle - The fastest way to check if some records in a database table? -

    -
    I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
