I am running a script in R Studio that I expect takes pretty long, how can I see if the script is still running though, as opposed to R Studio crashing? Right now R Studio just has that '+' sign in console, so I think that means it's still running.

I've been looking into running some F# scripts to automate some things. But I can't seem to be able to find a way to run the scripts. I've to an F# file.
Test.fsx
let helloWolrd = "Hello World"
printfn $"{helloWolrd}"
I know I can run it by selecting and running it with Alt+Enter but this just seems unpractical. How can I run an entire F# file in Visual Studio? Not by selecting the part I want to run.
As you noted you can send individual snippets of F# files to F# Interactive by highlighting the lines you wish to send using Alt + Enter keyboard combination in Visual Studio. The same works with VS Code.
You can run entire scripts using dotnet fsi script.fsx from the command line. This works from Developer PowerShell within VS or other CLIs.
I haven't used my VS in few months, but today I got the need to. So I wrote some code, pressed F5 to see if it compiles and works properly, it started showing compiling process in the bottom window, at the very bottom a Build Successful message shows up, and nothing. The app doesn't start up, I can't click anything in VS (isn't considered as "not responding" by windows), and Task Manager shows three processes named like my app, all having 112K memory usage. After I kill VS process, one of them closes, but I absolutely can't get rid of remaining two, until I restart my PC. Trying to run the exe in project directory also didn't work.
I'm reinstalling Visual Studio to see if it gets fixed from just doing that, but ideas on how to fix it are still welcome in case it doesn't.
Every time I run a program in Visual Studio 2013 it closes the console window directly after it asks for any more input from the user for the last time it's told to. I have put return 0; at the end of it, but that too doesn't fix it. And yes, I always run it with the StartWithoutDebugging option (ctrl + F5) as many people have resolved it with.
I've searched high and low for an answer on this webiste but with no avail. Any answers it seems that anyone gives is for a different IDE or I have already implemented it.
I'm trying to use the parallel debugger on visual studio 2010 for a project written in C using MPI. I set it up using instruction I had for setting it up in VS 2008, which I know worked, however when I run I see no output to the screen. Break points are still hit by every process, and I can step through the code and everything appears to process fine, however none of the standard output (ie printf statements) is printing to the screen. Never had this problem with 2008, and I can't figure out how to fix it. Any help is appreciated.
I am interested in programming c# in visual studio and I have a problem here. I have a mac book pro and installed parallel 7 and then windows 7. now I have visual studio 2008 installed on the machine but when i try to execute the command Console.Writeline, console would not stay open. it would just execute the command and in less than a second closes it down. is there any solution that I can use to fix it?
A console application exist after it exists the Main() method, that's most likely why the console window is getting closed immediately.
Try running the application using Ctrl + F5, or add Console.ReadLine() at the end of your Main() method.
You can run your application in debug mode with a breakpoint on the last line to get it to pause so you can read the console output.
This is a pretty common issue with Visual Studio development in all languages and there are several other ways around it. See the answers to the following questions on Stack Overflow for more options:
