Is there a way in VS2013 to compile a C# file without a project or solution?
This is useful, e.g. in editing some C# code quickly while preparing a Stack Overflow answer while scrubbing corporate IP from the file (without risking any harm to the "real project").
The build toolbar is grayed-out.
I know one can occasionally see squiggles for errors.
Any other simple ideas?
You can use https://dotnetfiddle.net/
You can specify different things in it. It is best for writing fast answers, also you can post link with your saved work. It is similar to jsfiddle if you aware of it.
You can use Snippet Compiler. You can download it from below URL.

Its a stand alone light weight small application.
If you have Mono C# installed then C# REPL is awesome tool to execute small chunk of c# code.

Do you guys by any chance know of a tool for visual studio that can scan the entire application and find code duplication?
I have to clean up a medium sized asp.net c# application and I am using "Find and Replace" but it is really tedious work. I was wondering if there was a utility or VS plug-in that could automate this process.
Thanks in advance!
you can give Clone detective a try
Perhaps PMD can help.
From the homepage:
Duplicate code can be hard to find, especially in a large project. But PMD's Copy/Paste Detector (CPD) can find it for you!
They have a list of similar projects.
Simian is a good tool to use. You can define code block size, and create an external command to run it inside of the VS IDE.

It's not for VS, but Simian works pretty well.

I have a big ASP.NET project full of hard coded strings, that now have to be extracted to resources. Such strings can be found almost anywhere (in .cs files, .aspx files, .ascx files, etc.) and the amount of files is huge. What I'm looking for is a tool (or any way) to find all these hard coded strings in one shot and put them all together in the resource file, instead of me going manually through each file. Does anything like this exist?
Note: I'm aware that it would have been better to put the strings in resources straight away when they were needed the first time, but this is a 2 years old project where nobody really cared (typical example of "not my problem" philosophy).
Thank you very much.
UPDATE: I tried CodeRush (I couldn't try RGreatEx for obvious reasons), and I'm having difficulties using it. The main issue is that the strings I'm looking for are located mainly in .aspx files, and strings in those files don't have the "Refactor to resource" command available.
For example, I can have elements like this:
<dxwgv:ASPxSummaryItem DisplayFormat="{0}" FieldName="TOTAL" ShowInColumn="Total" SummaryType="Sum" />
The part I need to change is ShowInColumn="Total" and make it like ShowInColumn="<%$ Resources:PortalResource, Total %>". This is not a string assignment in a strict way, but an attribute assignment, so the "Refactor!" command of CodeRush doesn't appear.
My target is to find all of them in one shot and change them in a specific interface (i.e. like a localization tool) instead of looking for them one by one and manually creating the corresponding resource. Refactoring one by one inside each file would be an improvement, but still very time consuming...
You could take a look at the resource refactoring tool at
http://www.codeplex.com/ResourceRefactoring
It's an instance-by-instance tool rather than a batch replacement tool. It's free and standalone so you don't need Resharper or Coderush.
Check out the new open source project VisualLocalizer on CodePlex: VisualLocalizer page. If you have some ideas, post them as issues - the project is under development and we welcome feedback.
VisualStudio lets you search and replace with RegEx. It won't be the "fix all in one shot" solution, but it should cut back on the amount manual work significantly.
Just a thought.
If you have a look at DevExpress' CodeRush it has the functionaility you are looking for, you may need to automate it to do it a all in one shot.
It has a great deal more too!
Kindness,
Dan
Try RGreatEx. This is a plugin for ReSharper:
RGreatEx is the most powerful localizer and coding helper for Visual Studio. Once installed, it lets you localize .NET applications and produce safer code, saving up to 95% of time the developer usually spends on doing the same by hand. Empower yourself with time-saving refactorings, such as "Move to resource" and "Rename resource". The plug-in will automatically analyze string and resource usage and suggest moving strings to resources.
Do you have ReSharper? Then you perhaps should wait for version 5.0. It will have RGreatEx (mentioned by Anton) functionality included. Read the thread from the R# forum on this topic.
Update: The feature will be in R# 5.0. See the official announcement.
I've just published new tool called Jinnee.Package for string refactor. You can find it on Visual Studio gallery:

I am trying to learn Windows.Forms, and while I have Visual Studio (edit, my mistake obviously), I feel that I learn much more effectively by doing everything in Notepad. I have searched everywhere for a tutorial that takes this approach. I finally got started with http://www.geekpedia.com/tutorial33_Windows-forms-programming.html, but after the first example, it too begins working with multiple files? somehow generated with Visual Studio. How can I do this in Notepad? Can anyone point me somewhere helpful?
Thanks!
**While the overwhelming response seems seems strongly against this and I started to be convinced, I saw SmokingRope talking about it being as simple as writing all classes into one file. This is what I have been doing up till now for sizable, just non Windows.Form projects into. Can you maybe help explain how those necessary files can be included using this method?*
Seriously... I admire your fire, but you are out of your mind! What you can possibly hope to learn about .NET with NotePad that you couldn't learn a zillion times faster with Visual Studio? It's like asking, "I want to learn to drive a car. I have put wheels on my couch. What should I do next?"
I mean no disrespect, but make friends with Visual Studio and get busy learning. You're wasting your time otherwise.
It is actually quite easy to code C# outside of the IDE. It will basically come down to using the csc.exe compiler from the command line prompt.
The hardest part of this process is making sure the environment variables are correctly configure and Microsoft provides the vsvars32.bat batch file to do exactly that.
Here is a short tutorial on how to do use this batch file and the compiler from the command line: http://www.zeusedit.com/forum/viewtopic.php?t=1235
And an even better, but slightly more complicate approach is to use MsBuild utility to manage the building of the project: http://www.zeusedit.com/forum/viewtopic.php?t=2518
Finally you can even use the external C# Debugger to debug you programs: http://www.zeusedit.com/forum/viewtopic.php?t=2507
Your best approach is really to learn how to write code from within Visual Studio. You gain a lot of coding assistance (IntelliSense, syntax checking, etc.) that will help you learn the language.
If you really want to use Notepad, then you create as few or as many files as you want and then compile them in to an assembly using the command line compiler by listing each file as an input to the compiler.
The reality of this is that using notepad and the command line compiler is possible but very cumbersome and almost never used outside of showing simple "Hello, world" type examples.
I am going against the grain here... But I think that your idea is not such a bad one... especially for a small project.
But using Notepad (or at LEAST use Notepad++) will teach you more about MSBuild and the VBC or CSC compiler syntax than it will teach you about the language features. The best way to learn the language, is, as other have said, using Visual Studio. The intellisense is a great way to learn.
But it also makes us lazy and it is true that we don't have to memorize as much...and sometimes having things memorized comes in handy. (ie.... I am at a customer and logged in remotely to the servers... no visual studio is installed... BUT... yippee... .NET 2 is there... at that moment you will have appreciated the exercise...)
Honestly, to do this for a reasonably small project I think would be a good exercise in learning. I say go for it. Hell, I might even join you.
But, that said, I think the very best way to do it would be to use both methods side-by-side. For example... If you want to use multiple files the way to do that is to create a folder and put an vbproj (or csproj) file in it. MSBuild.exe receives vbproj files (and sln files for that matter) as arguments. So, one of the quickest ways to learn the vbproj file syntax is to use visual studio to create a project... and then open the vbproj file in Notepad++.
The problem is that Visual Studio IS SO AWESOME BECAUSE it abstracts so much away from the developer. But it is silly to not acknowledge there is a downside to that. That abstraction means that we don't need to have as deep an understanding. Things just work automagically. So I say dig a little deeper. I don't think you will regret it.
Assuming that the thing you want to avoid is magically-generated-code and visual designers, you can just open the System.Windows.Forms namespace and start coding against the APIs. Start with that first example, and then programmatically add buttons and textboxes and whatnot. You don't have to create a forms project or work with the designers, you can just 'write code' in VS and turn off all the magic.
If you're looking for example code, you might consider looking at F# samples, e.g. the UI stuff at
http://code.msdn.microsoft.com/fsharpsamples
for ideas of a few basic controls you can add to forms to do basic UI stuff.
You can write multiple classes in a single C# file (despite the generally accepted best-practice of putting one class per file):
using System;
namespace Test{
class Class1{ }
class Class2{ }
}
You also could look into how the MSBuild system works from the commandline. I believe you will still have to maintain a project file (xml type syntax, use visual studio to create a project and then open that in notepad for an example) but i don't have any experience with it personally.
It's possible to do it all from notepad and the command prompt. You will probably find it to be a little more time consuming however.
If you want to learn c# and winforms, part of the skill set you need is being proficient in Visual Studio.
You can do things in Notepad for awhile (I wrote some web services in notepad once because I didn't have VS available), but eventually you will want to take advantage of the tools available in VS.
I highly recommend you use Visual Studio (Microsoft offers free Express versions that will meet your needs). Learning the syntax of the language is wonderful, but you must be able to work within the VS environment to be truly successful in C# (and any of the .NET languages). It benefits you more to do it right and learn it all together rather than try and piece it together later. Just my own two cents.
Just to repeat what's already said, again with no disrespect, you are not going to learn .NET in notepad. It's just not probable. Not only are you not be productive, but you're also not going to learn the tools used in the industry, best practices, and other important factors about .NET. It's not just about sitting down and writing code. By limiting yourself to notepad, it's like limiting yourself to one meal a month: you lack the nutrition needed to keep moving forward at a good pace.
Utilize the tools and resources available to you. Limiting yourself like that is a kick in the rear end.
Use sharpdevelop (Windows) or monodevelop (*nix). Both have Windows.Form support. Although they dont offer as much as VS, they'll at least get you started. I've never used the VS Express edition, so I don't know what it's limitations are.
Note that notepad is not even the equal of vi not to speak of vim.
If you want to use a text editor then you could try it but I don't see the point of using notepad. Use a real text editor, not necessarily vim/emacs, you could pick a nice gui text editor like notepad++ or kate.
Notepad can't even display unix line endings(I think).
Go download an Express edition of Visual Studio. I understand the possibility of thoroughly learning this via notepad, but with a free IDE out there, it makes no sense.
if u have something against MS or VS.net u can try sharpdevelop
http://www.icsharpcode.net/OpenSource/SD/
last time i looked it was xcopy deployable :)
I don't know where to find tutorials, but the approach is pretty straightforward: import System.Windows.Forms, derive a class from Form, and give it a .Show(). Your components are members of the class, and can be positioned using their respective position/size properties. Events are handled through delegates.
I do see where this technique is useful, though I'd use a decent IDE instead of Notepad. .NET is just too prolific. Knowing how to construct forms on the fly can come in handy.
If you're looking for an alternate IDE, check out icSharpCode's SharpDevelop.
Also, look into JScript.NET tutorials - there is no forms editor for that language, as inheritance simply isn't possible. But it's still based on .NET, so the basic motions are the same. Here's a decent one:

I know this is answered by strangely I haven't seen anyone talk about NAnt.
For years I developed in TextPad, with some syntax highlighting, + NAnt to do my builds. These days it'd be even easier as you can have your buildserver prep a proper msbuild for you (CC.NET + NAnt).
I also learned about a few things that physically couldn't do in Visual Studio (at the time it was .net 1.1). Definitely a good experience, and I'd recommend it really. Probably not for winforms though, because the designer is actually useful for that.
i am a notepad user. :) i don't have visual studio installed on my computer.
this is what im doing.
1st u must register your .net framework folder on Environmen Variables.. Path
or run on CMD this lines
path=%path%;(this is where ur .net framework address were)
(ex path=%path%;C:\Windows\Microsoft.NET\Framework\v4.0.30319)
then hit enter
2nd to compile a single notepad(save as .cs), locate the destination of the file using cmd. then. type "csc nameOfCS.cs"
for multi file.. "csc ManinCsForname.cs classes.cs classes.cs"
it will compile as exe.
for more command.
"csc /?"
its ok to use Visual Studio. but if you want to become more familiar with C# and structure. or can make a system on any PC. without using any IDE. u can do this.
Not using Notepad will help. Crimson Editor or TextPad or others have line numbering, syntax highlighting and many features you'd need. I'm sure Notepad has file size limitations which you might run into.
The sans-IDE element I can only fully answer from a Java point of view. I've done a fair amount of Java UI development using Crimson Editor, the Java SDK, batch files and/or either ANT or Maven at times. If you developing UI code that's generic or does a fair amount in dynamically then its ok. If your work involves designing many different specific Forms (i.e. screens that have many customer forms and aren't subject too much reuse) then the Designer features of the IDE are extremely useful.
However, I have found .NET IDE development a little frustrating coming from the above model of Java development.
yes, this is a very noobish question. I'm a .NET developer and I need to step through some java code to see exactly what is going on so i can port some java into some c#. So far i've not needed to do that .. until now.
So .. i have absolutely zero knowledge of java debugging. So can someone please explain in blond-speak how i can debug the following java program, and specifically ... this line/method in the following
=> code source zipped, found here.
=> line of code: \src\com\yahoo\platform\yui\compressor\JavaScriptCompressor.java :: line 550 ... buildSymbolTree();
Now, to add to my embarassment, I have no idea what program i need to download, what steps i need to do to add this java project, add a breakpoint, start debugger, etc.
I would appreciate it if someone could provide some steps to doing this.
Oh .. this will be all installed on a virtual pc running windows xp.
The only thing this virtual pc has installed on it (currently) is windows xp & the java runtime (jre-6u12....)
Thanks kindly!
Steps (will update when more info comes in)
Grab/install NetBeans Ide from here. (Program to debug java with).
(how to open an existing project?)
(how to make a break point?)
(how to start debugging .. including defining the command line args to read in the file?)
(how to make a watch item?)
Wiki Mode
Made this a wiki so other people can edit/update the steps.
Pick up netbeans or Eclipse; they're decent IDEs with decent debuggers. If you're an old fart like me, you can also use jdb, which ships with the rest of the java stuff. That's a command line tool, similar in concept to dbx and gdb.
Okay, looks like maybe it's even more detail needed.
You're going to need a Java environment. if you grab either of those IDEs you'll be able to pick one up. However, you can go to http://java.sun.com and download a JDK for your environment. You want a JDK, not a JRE (Java Runtime Environment) because you want the compilers and tools.
Another good resource is the Java Tutorial, which will lead you through the basics of setting up aqnd such (and teach you the language if you want to go into it more deeply.)
One warning: C# is almost but not quite wholly unlike Java, but it's hidden under very similar syntax. Be careful in your translation that you're getting Java that means what you think it means.
You should be able to transfer your debugging skils from VS, since the debuggers across netbeans & eclipse are very smiliar. Assigning breakpoints is very much the same and I'm almost certain the same hotkeys are used to step through the code.
Below are some nice tutorials which may be of use to you.
Eclipse Debugging Tutorial
NetBeans Debugging
I have not used this in a long time... but it is a stand alone debugger: http://code.google.com/p/jswat/
I use Netbeans myself. For what you want to do, if you try Netbeans make a new Java project from existing sources and go from there.
If you have used the Visual Studio debugger then Netbeans, Eclipse, JSwat, etc... should be easy enough to figure out.
