I have been using Visual Studio 2010 Pro for my vb.net desktop application development. I publish the apps via clickonce to a web server with ftp. My settings look like this:
Publishing folder location: ftp://www.webaddress.com/folder/
Installation folder : http://webaddress.com/folder/
This works perfect in VS2010.
I am now trying to upgrade to Visual Studio 2015 community edition. When I try to publish my app, I get the error "The components for communicating with FTP servers are not installed". I am getting this error on both computers I have installed VS2015 on.
Strangely enough, there isn't much info on this error. The only solution I've seen is to repair the installation. I did this but still a no go.. Another cause I read about is having Xamarin installed, but I have never had that installed.
Has anybody run into this and know what the fix is??
EDIT:
It appears to not actually have anything to do with installed components. After I posted this question, I realized the publish via FTP had worked earlier on a little sample Hello World project i made (brain fart). It was only once I loaded my existing project that this error started showing up.
I closed the solution, created another simple project, and still got the error. I closed visual studio, reopened the sample project, and ftp worked! I then opened my existing project and ftp worked there too?! So I don't know what the trigger is, and I haven't had it fail again yet, but maybe this info will help figure out what is causing the failure.
EDIT (3/30/2017)
Just an update - I am still having this issue. This issue happens on visual studio 2013, 2015, and 2017. I have tried reinstalling the c++ redistributable, still nothing. It seems others are having this issue with a web project but mine is a desktop app publishing with clickonce via FTP. It must be something to do with solution I am working on that was originally created in 2010, as the issue is not present in any other project.
I had the same issue with Visual Studio 2017. What fixed it for me was to start the Visual Studio Installer and install the ".NET Core cross-platform development" workload.
I had the same issue in Visual Studio 2015 / Update 3. It was resolved after installing the 32-bit version of Visual C++ Redistributable Packages for Visual Studio 2013 (https://www.microsoft.com/en-us/download/details.aspx?id=40784)

I had the same problem with Visual Studio 2015. And Publish used to work fine so I went going crazy looking for and trying different solutions. Then I read on another thread of doing a Setup-> Repair (submitted by Erikest). I did a Setup->Repair and the publish process now works! I think it's also possible that the Repair not only did the trick on the FTP components but also replaced the C++ redistributable (often mentioned as a solution to this problem),
This is a total work around, but I've noticed I get this error every time I open my app (that originated in VS2010) and try to publish without first opening a sample app. I created a new project and published it to my FTP server. When I receive this error, I close Visual studio, reopen and the open the sample project, publish that app, then open my real app. The publish then works.
This works every time, and seems to be a bug in Visual studio, and probably has something to do with the fact that my app was originally built in 2010.
Maybe this will help somebody else with the same issue. It's a big pain so hopefully MS gets a fix in for this.
I have been banging my head against this problem for many months, re-installed VS over and over and just did a clean install of Windows 10 in the hope it would work but to no avail. By chance I cleaned some old .accdb files from the App_Data folder that I no longer need since I converted to SQL Server database and FTP publishing now works.
So it seems VS does not like the .accdb files but was happy with .mdb files when publishing with FTP.
As soon as I put the file back in App_Data the problem returns. Hope this is some help.
I had the same issue here, I was using the Publish right click option on the project, which had been working fine. What fixed it for me was going back through the publish options and re-testing the connection. Publish seemed to work after that. Maybe it forgot a password or settings?
I also installed the x86 C++ Redistribution Package.
Hope this helps someone who is in the same boat.
After many successful website publishes with Visual Studio 2015 Community Edition, we experienced the "components for communicating with ftp servers are not installed" issue. :(
First attempt at resolution was uninstalling VS Community 2015, then installing VS Community 2017. Received the same error: "components for communicating with ftp servers are not installed" when attempting to publish our business website.
With some work, we found that by uninstalling Microsoft Web Deploy and re-installing, this seemed to fix the problem. We can now use Visual Studio > Publish function to our ftp without problems.
See this link for download of Microsoft Web Deploy components.

Dont know what broke this VS IDE functionality, but hope this fix helps some.
I encountered the same error with Visual Studio 2019
I fixed it by using the Visual Studio Installer to install the Web Deploy (inc .netcore 2.1) under individual components
I just did a simple "repair installation" in the installer. Worked for me.
I am using Microsoft Visual Studio Community 2019 and had this problem for a while.
The problem went away after I updated about 10 NuGet updates that were over due.
I had the same problem, I closed all the open windows I closed Visual Studio and then I opened again and published and then it worked!
I've created a C++ UWP Windows 10 app using Visual Studio 2015. However, I'm not able to visualize any xaml in the designer because I'm always getting a System.NullReferenceException error. How can I fix this?
That's very odd but I solved following these steps:
Close any instance of Visual Studio
Open Visual studio and create a new C# UWP empty project (name it as you like, do not matter)
Run the "useless" created project then close it as Visual Studio
Open again your previous C++ UWP project
In my case everything started working!
Switching solution platform to x86 worked for me.
I'm experiencing exactly the same problem on my primary development machine but not on another. The reason is... I think... When I installed Visual Studio 2015 on the 2nd machine, the first time I created a Universal Solution (C#) I was shown a dialog asking me to OK "elevated permissions" (custom permissions) for the VS2015 installation folder. I OK'd it and Designer works on that machine in both Blend2015 and VS2015 (community edition)
On the other machine I was never shown the dialog asking me to confirm elevated permissions and Designer does NOT work on that machine (VS2015 Enterprise). This machine also has VS2013 update 5) on it.
I am thinking that I might have to completely wipe off VS2015 and try to clean the registry of all VS2105 references AND remove the VS2015 installation directories on C:\ AND when I reinstall, create a installation directory with a different name (if I can). What a PAIN though... I'm waiting to see if MS delivers a simple solution since I'm quite positive that this whole issue boils down to a bug (feature... grrr) having to do with custom permissions that can't be changed (or added) after installation.
Would be nice is MS would confirm this...
(please note, none of this involved c++... it was all C#)

this is the dialog I was shown on the machine where Designer works]1
Installing the Windows Software Development Kit (SDK) for Windows 10 solved the issue for me. It may ask to unistall the previous version of Windows 10 RTM SDK
https://developer.microsoft.com/en-us/windows/downloads/windows-10-sdk
This is fixed in Update 1 of Visual Studio 2015

So I have a program I've been making in VB for my company through Visual Studio 2013 Express for Desktop and have not worked on it in a couple of months. When I try to open it, I get the following error:
"The VB project "WindowsApplication1" is targeting ".NETFramework,Version=4.5" which is not installed on this machine."
http://imageshack.com/a/img661/6001/DGAfuk.png
I have all of the .NET frameworks installed including all developer and service packs (even language packs). I uninstalled all .NET frameworks and re-installed each of them without any resolution.
I tried to re-install Visual Studio and even tried changing the Framework (one of the options I have) but I cannot view any code or open designer view if I do so. (http://imageshack.com/a/img633/2109/OJaXbr.png)
The strange thing is this computer is the same one I have been developing this application on for months, so I'm not sure what happened over the last 60 days since I launched it.
Does anyone have any clues as to how I can resolve this issue?
Thanks in advance,
Matt
The path to your project must be Les then 256 Character.
That can be the reason of it.
Make sure the path is short "Copy the project to your c drive "C:\ProjectFolder" and try again".
i've got computer with Windows 8 and fresh installation of Visual Studio 13 Express.
I'm working on project which runs on .NET 4.0 Client profile.
Problem is when i try to complile, this error message is shown:
Solutions:
social.msdn : This one says:
try to restart your VS and rebuild - not working
check MSbuild from promt - not working (Message is shown twice)
I also checked project configuration vsproj and tried to make sample project
Reinstall framework:
i tried ot reinstall almost everything, framework, sdk.
when i've installed .NET Framerork v4.5.2 my VS was unnable to start and anoter .NET apps complied before had missing library
I haven't tried to reinstall VS, yet. (But i dont think if it helps)
Edit: Temporary solution shoud be Visual Studio Express 2012, but it not solves problem.
Reinstalaion of VS didn't help.
Background
We're using System Center 2012 to deploy a Windows 8 Metro-style application to Samsung slates in the field running Windows 8 Enterprise x64. The slates are joined to the domain and have a persistent DirectAccess connection back to it, allowing System Center to push applications and updates to the devices.
We have to deploy our application to potentially hundreds of devices in the field, which is why we went the System Center route. The code signing cert is installed on every device using Group Policy. To deploy the application, you simply provide the package output and specify the collection of devices to install it on. The app just shows up on the device in a few minutes.
The problem we're having is that when System Center deploys our application, the SQLite dependency is lost and none of our data access works.
About our project
Our application is a WinJS application that uses SQLite as a backend. However, all our data access code is in a C# WinMD project which the WinJS project references. We're using the sqlite-net library to talk to SQLite - we included the source for that in our C# project.
In Visual Studio, we installed the SQLite for Windows Runtime extension as described in Tim Heuer's article. The Metro application references this.
Testing using other deployment methods
SQLite data access from the application works fine when you debug or run it locally - in both Debug/Release and x86/x64.
The app packaging process provides a PowerShell script that you can use to install the application and a developer license if necessary. When installing our app using the PowerShell script, SQLite data access also works fine. Verified this by packaging and installing both Debug/Release and x86/x64 versions of the app.
Troubleshooting
When the application first tries to use SQLite, we see an exception about it not being able to find the sqlite3.dll.
We've tried/verified the following:
Confirm that we're deploying a Release/x64 build
Examine the appx in WinRAR and verify that it contains the sqlite3.dll
Reference the "SQLite for Windows Runtime" extension from the C# project instead of the WinJS project
Also reference the C++ runtime, this caused System Center to fail when deploying the app. Don't know why yet, but looking into it.
UPDATE
The issue is that System Center is having trouble deploying the Visual C++ Runtime Library dependency that the SQLite library needs. So unfortunately this isn't a programming question anymore. We're getting some help on this and I'll post the fix.
I wanted to post the details of a temporary fix that we're going with. We've also gotten closer to the root of the problem, so I wanted to provide those details as well.
Recap of Issue
When referencing the Visual C++ Runtime Package from our Metro project, System Center is unable to deploy the application to the devices because there is a problem deploying the proper version of the dependency for the appropriate architecture and build flavor.
Our development machines running Visual Studio 2012 (and packaging the project for deployment) are using a newer version of the Visual C++ Runtime (50727) than what is available in a fresh installation of Windows 8 (50712).
Worked with the System Center team and confirmed that this was a bug in the version we were using and has already been addressed in future builds. We're going to work on upgrading the environment but that will take a couple of weeks.
Workaround
I confirmed and tested the following workaround:
Remove the reference to the Microsoft Visual C++ Runtime Package from the Metro project
Install the x64 version of the Visual C++ Redistributable for Visual Studio 2012 - http://www.microsoft.com/en-us/download/details.aspx?id=3
Deploy the application
Works like a charm because the correct version of the dependency is there already. Obviously not a long term solution if we choose to also target x86 and ARM, but will get us over this hump.
