Attempting to run C# on cloud9 IDE but receiving errors

I’m new to Cloud9 and I’m facing some issues.
I’m attempting to run the C# code on the IDE and am failing to do so, I think I know why but I cant seem to be able to resolve the issue.
The picture uploaded below should have everything needed to solve the problem
enter image description here
Upon further research, I found a link that goes through a step by step process on how to install .NET core. However, I'm having issues, with setting the project template using this code for the terminal dotnet new console -lang C#
It starts decompressing then stops at 99%. (as indicated in image below) The first error that pops up states that System.IO.IOException: No space left on device not sure what to do with this though.

I kept on attempting the same code and it has managed to complete the decompressing stage only to start resetting again at the Expanding stage. (Refer to image below).

Run C# is not yet supported on Cloud9 IDE
https://docs.c9.io/docs/supported-languages

I think #shingo is correct to say C# is not supported BY DEFAULT. It is possible, however, to make it happen as shown in the links below, but not advisable as there is little help out there. I wouldn't do it if I were you.

Workflow designer asking for generated file reload every time C# expression is edited in VS 2012

I'm using VS2012 and .net 4.5. Whenever I edit C# expression in properties window I get message as shown in below image
Update:
I did not open this file. Neither in VS nor in other program. I think VS loads this file for some reason.
If I open C# expression dialog I get similar behavior to the one described here
I also often get error saying that VS cannot access this 'TemporaryGeneraterdFile_' cos it's being used by another process.
This post describes that error.
Did anyone experienced similar behavior?
It's realy anoing as it happens very often.

How to check in only some parts of the program in Visual Studio Team Services?

Additional info: I thought it might be helpful to say that my forms and classes are in the same solution as the already updated forms.
In our company we have this project which 3 people are working on it. One works on the database part, me and another colleague of mine are working on making the UI ready and relating it to database which is MS SQL Server 2012 and we are programming in C# in VS 2012.
The problem is that I made this one form ready, but the server version is ahead of me. That is, if I check in the whole program, I will damage the project as some forms has changed and the version I have is older. I tried right clicking and checking in only the forms and classes which I, myself made and I have their latest version. They check in without any error or anything, but the problem is, when my colleagues or myself(after deleting my source project) try to get latest version, my forms or classes doesn't show up.
We also tried to check in the whole program but only accept those pending changes which are made by me, still no success.
The problem is, we are kinda afraid to play with the server version as a lot of effort has gone into it.
Any help will be really appreciated as I'm stuck with this problem and the manager won't give me more parts of the program to make until we can come up with some way to deal with this.

You haven't mentioned merging at all but I think this is the answer to your question.
When you work on an older version of the code (because your local code is older, or maybe the whole branch of the code is older), you need to merge the code into the newer version. When you merge, any potential conflicts are detected and you can resolve all of them manually. There's obviously tools to help you - one is built into Visual Studio but you can replace it with an external tool which may work better for you. Either way, you need to decide how to merge the code. You have a few options:
take the whole code from the source (old code in this case),
take the whole code from the target (new code in this case),
merge the changes and take bits from each version based on your knowledge of the changes and how the code should look like.
As for why the forms don't show up, you probably didn't check in the changes to the project file so the new files are not part of the project as it exists in Team Services.

Error 1001 An error occured in sending the command to the application

COM Excel AddIn, C#, VS2008
The error happens occasionally when I install/uninstall my AddIn.
sometimes I see Error 1001 the specified file can not be found
Anyone know what causes these and how to fix? thanks
I use windows installer
http://msdn.microsoft.com/en-us/library/2w2fhwzz%28v=VS.90%29.aspx says if use [TARGETDIR], it should be like "[TARGETDIR]\" or "[TARGETDIR] ". I simply use /filepath = "[TARGETDIR]myinstallfile" in CustomActionData
What I do not understand is it works almost all time and fails occasionally
Also even if I change this to including space or backslash, I can't tell if that fixes issue since the issue does not happen every time. Anyone has experience? thanks

I found this and it fixes the issue though I am not sure I ever use DDE in my program
http://sympmarc.com/2010/02/04/microsoft-excel-error-there-was-a-problem-sending-the-command-to-the-program/

Then I found this http://www.opendylan.org/documentation/opendylan/interop2/inte_278.htm
It talks about COM Server
so I went to cmd, type in "Excel.exe /RegServer", then the error disappears.
I am not really not sure if this solution works for all cases.
In fact, I am concerned that I miss sth in installer.

Here is a Microsoft Support page related to an issue which looks quite similar to yours. So for me it looks like a bug in Excel rather than in your installer.
The article is quite large, but it boils down to making sure that:
your Excel app is not running with elevated rights
advanced setting "Ignore other applications that use Dynamic Data Exchange (DDE)" is unchecked
Other than that you might try to repair Excel installation or follow the advice given in this thread of ASP.NET forums to fix the registry for Excel installation.
I hope it helps someone facing similar issues.

If you get this type of error when uninstalling a VS setup project MSI, then the most likely reason is that TARGETDIR is not preserved between the install and the uninstall, therefore it has no value, and attempts to use it in an uninstall custom action will result in failure to find the file. The easiest solution (apart from always installing to known locations such as common files etc) is to save TARGETDIR to the registry and retrieve it later. In the VS IDE you can create a registry item with the value [TARGETDIR] to have it resolved at install time.

Getting csharp-mode Emacs syntax highlighting working

Googling "csharp mode emacs" yields the page
http://www.emacswiki.org/emacs/CSharpMode
which includes a few links to various downloadable emacs lisp files. The 2005 link (DylanMoonfire) is broken, so I downloaded:
http://lists.ximian.com/pipermail/mono-list/2002-May/006182.html
as ~/.emacslib/csharp-mode.el
and added:
(autoload 'csharp-mode "csharp-mode"
"Major mode for editing C# code." t)
(setq auto-mode-alist (cons '( "\\.cs\\'" . csharp-mode ) auto-mode-alist ))
to my .emacs file (anywhere, beginning, middle or end). I attempt to edit a new text file called "t.cs" and I get the error:
File mode specification error: (error "Buffer t.cs is not a CC Mode buffer (c-set-style)")
and no syntax highlighting. I'm not well versed in emacs-lisp but I know enough to install support for loads of language modes and csharp-mode is just not playing nice compared to every other language mode I've installed.
I was getting excited to play with Mono on my Mac and ran into this ridiculous barrier! Anyone out there know how to get decent support for C# syntax highlighting in emacs?
Note: I'm using a MacBook Pro running Emacs 22.1.1 on OS X Leopard.

I found a more recent version of csharp-mode 0.7.0, go to the end of the page and download as plain text. Haven't tried loading the mode however.
Just uploaded the code to emacswiki as well: charp-mode.el

What you have seems to be very outdated. It's too bad that the more up-to-date version was not hosted somewhere safer, like the Emacs core, EmacsWiki, or Github.
But anyway, you might as well try asking on #emacs (Freenode) and see if someone can send you the more up-to-date file.

I made a slight modification to make Tab indent 4 spaces and deal with braces correctly, so now hitting tab on any line "does the right thing" with respect to conventions in Visual Studio.
http://www.updike.org/files/csharp-mode.el

The EmacsWiki page for CSharpMode says that the most current version of this package can always be found on github (josteink/csharp-mode).
Maybe you would like to use OmniSharp-Emacs that provides IDE-like features for editing files in C# solutions in Emacs.
