I have an ASP NET MVC 4 project that "works on my machine(old)". When I load a project in a fresh installation of VS 2015(on a new laptop) - a lot of assemblies are missing and when I try to build the project it complains that classes like ActionResult, Controller are missing.
I checked that on the old laptop the missing dependencies are coming from C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 4\Assemblies. On the new laptop I have only the xml descriptors of the packages but not the dlls.
What I have to install to use MVC 4 in Visual Studio 2015?
Edit: missing dependencies are:
System.Web.Helpers
System.Web.Mvc
System.Web.WebPages
System.Web.WebPages.Deployment
System.Web.WebPages.Razor
I Recommend getting them again from Nuget for your ActionResult Issue its Microsoft.AspNet.Mvc which is making issue.
Open Package Manager Console and insert the command below:
Install-Package Microsoft.AspNet.Mvc
Nuget has this feature that allows you to restore all the missing Assemblies which exists in nuget. you can try that out as well.
Anyway for the rest of them install these packages below as well:
Install-Package Microsoft.AspNet.WebHelpers
Install-Package Microsoft.AspNet.WebPages
Install-Package Microsoft.AspNet.Razor
Check if you have install update 3 for VS2015
also check if Microsoft web developer tools are installed correctly
I have had the same issues when using source control or moving projects from one PC to another.
There is a work around that I use quite often and it works.
Go to YourProjectFolder -> packages.
Remove all the folders except for the xml, repositories.xml, file which is the xml config file for packages downloaded from Nuget.
On your solution in Visual Studio Right click and select Enable Nuget Packages Restore.
Then build the application it will re-download all the required packages.
Hope this helps
For Me what solved the issue is to install ASP.NET MVC 4 for Visual Studio 2010 from Microsoft Web Page

I'm trying to install emgu.CV.runtime.windows from within Visual Studio 2017, and installing by the recommeded method of right-clicking references and installing via NuGet.
However I am getting the error below.
Could not install package 'Emgu.runtime.windows.msvc.rt.x64 19.28.29336'. You are trying to install this package into a project that targets .NETFramework,Version=v4.7.2, but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.
According to the package information, its dependencies are
enter code here.NetStandardVersion=2.0
enter code here.Engu.CV (> 4.5.1 && < 4.5.2)
enter code here.Engu.runtime.windows.msvc.rt.x86 (= 19.28.29336)
enter code here.Engu.runtime.windows.msvc.rt.x64 (= 19.28.29336)
I checked and c:\windows\Microsoft.NET\Framework contains a folder for v2.0.50727, so it seem .net 2.0 is installed (as is v3.0, v3.5, v4.0.30319)
I have emgu.CV 4.5.1.4349 installed.
I need this library so that I can have the enter code herebitmap.ToImage<Bgr, byte>(); function.
Why am I getting this error?
Any help would be greatly appreciated.
The solution is migrating from package.config to package references for every project you have. Simply right click on package.config and click "migrate package.config to PackageReference".
Then, install the runtime package again and it will work.
For the new Emgu Nuget package you do need to use PackageReference instead of the traditional package.config.
What worked for me on Visual Studio 2017:
Uninstall all NuGet Packages [This removes the package.config file]
Go to Tools --> Options --> NuGet Package Manager --> General
Change the default package management format to "PackageReference"
Check "allow format selection on first package install"
Click OK
Install Emgu.CV, Emgu.CV.Bitmap, Emgu.CV.UI and Emgu.CV.runtime.windows
These Emgu packages should now appear under your references and you should not see a package.config file.
Nuget Options Image
I encountered the same error. I don't know why we're getting it, but I was able to find a workaround.
Visit the nuget page for the package.
Click "Download Package" to download the nuget package directly.
Open the downloaded file using your archive utility of choice and navigate to the "\runtimes\win-x64\native" folder.
Copy both dll files into the output directory of your project.
After doing this, my code executed without error. Make sure to install emgu.CV.Bitmap as well.
I changed my projects Target Framework to ".NET Framework 4.6" and then went to "Manage NuGet Packages", selected "Browse", typed in "emgu.cv.runtime" then installed version 4.5.1.4349 and it worked.
Here is how I solved it,
1- downgrade .Net framework to 4.6 from project properties
2- Uninstall Emgu.CV and related ones (you will see which ones needed to be uninstalled in Errors List)
3- Install Emgu.CV.runtime.windows from Solution Nuget Manager ( it should install fine now)
3- upgrade .Net framework to 4.8
4- install Emgu.CV 4.5.1 (latest)
5- install Emgu.CV.UI 4.5.1 (Emgu.CV.Bitmwp was installed automatically for me)
and that's it, now you can use bitmap.ToImage<Bgr,Byte>(), note that the Image<Bgr,byte>(bitmap) doesn't work anymore.
I am trying to make Newtonsoft.json available for use in my local Visual Studio 2010 projects. I installed NuGet.Tools on my system. Now I see an item in the Solution Explorer called Service References that wasn't there before, but I don't understand how to use that to reference the Newtonsoft package I also downloaded, which is currently in my Downloads folder. Do I need to move the package to a different location to reference it?
Thanks for your help.
You can right click on the project where you want to install newtonsoft nuget package.
You will find an option "Manage NuGet packages".
Then search online for "newtonsoft".
This would add a packages.config file in your project (depending on which framework you are targeting to ).
this new file contains all the nuget dependencies required for this project.
Refer this blog for more details
VS2010 is old and is unable to update to the latest NuGet version. This means that adding recent packages will often fail; however, you can often add an older version of a package that has a compatible NuGet version and it will work. This causes the suggested answer by #ManojChoudhari to fail for me. In the case of Newtonsoft.Json, the following worked using the Package Manager Console:
Install-Package Newtonsoft.Json -Version 9.0.1
After I download my project from GitHub and try to compile it I am running into the issue of "package requires NuGet client version ... or above" but I am using Visual Studio 2017 with the latest NuGet version for that version. The issue is fixed after building the package twice but is there a way that I could stop this from happening in the first place and have it so that these issues go away after the first compilation of the code?
I had a similar problem while adding NUnit via Nugget Manager. Instead of adding the package via Nuget Manager, I downloaded the framework's dll files from their website and add them as a reference to the project.
If you still want to use the NuGet manager, you have to upgrade to a newer version of Visual Studio
I have a project that i cannot compile. When i try to do so I get the following error:
The 'Microsoft.Bcl.Build 1.0.14' package requires NuGet client version '2.8.1' or above, but the current NuGet version is '2.7.41115.310'.
Normally this would be simple. After searching I found this guide:
http://www.daimto.com/package-requires-nuget-client-version-x/
That explains how I can upgrade my Nuget client version. However, when i follow those steps, I find that I am already using the latest version of Nuget: 2.8.5
For some reason however, Visual Studio 2013 Ultimate is using an older version, and I don't understand why.
My install of Visual Studio Ultimate 2013 is a fresh install, after unninstalling Visual Studio for Web Express 2012. The previous version was giving me a considerable amount of problems and so I deleted it and moved on to 2013. I wonder if some cofig files were passed through, but I cant be sure.
How can I fix this problem?
From Tools → Extensions and Updates → Installed, uninstall “NuGet Package Manager” and install it again.
So, after searching around I found no answers, so I decided to look into the project folders. It happens that I have the main version of NuGet.exe, 2.8.5 in main folder, but the project was nowhere near that main folder.
This way, when I downloaded the project it simply used the NuGet version pulled from TFS (or so I assume), and that was the problem - that verison was Nuget.exe 2.7.4.
After replacing the "Nuget.exe" files (found in /.nuget folder of the project) the project finally compiled and everythign started working again.
You can also try update Nuget Package Manager directly from Tools > Extensions and Updates
In my case, a pending update of Visual Studio fixed the nuget version.
The update was the "Update 5" for VisualStudio 2013.
The update was listed under the menu Tools → Extensions and Updates, on the tab Updates.
I was getting this error from a recently cloned branch, but (in contrast to the above solution) found that my Nuget version in the project directory was the same as that in my solution directory.
I solved this by right clicking on the solution and Managing Nuget Packages for the solution. The Nuget dialog that popped up said that packages were missing and asked me to restore them. Once downloaded, the project built successfully.
I had the same issue when trying to install System.Net.Http and it said the nuget version needed to be version 3.0 or above. I tried few things but in the end, used Tools and Manage Nuget Packages and did a search and tried to install it from there when it said exactly the same thing - wrong version of nuget, but it popped up with an upgrade Nuget button too!
Hope this helps someone
Simply reinstall nuget in visual studio
I am following this article on RazorGenerator and it say's that I must add references to:
System.Web.Helpers.dll
System.Web.WebPages.dll
System.Web.Razor.dll
The only one I can see when I do Add Reference is System.Web.Razor, but I don't know where the other ones are.
You will find these assemblies in the Extensions group under Assemblies in Visual Studio 2010, 2012 & 2013 (Reference Manager)
To sum up all of the options for VS 2017, WebHelpers was installed by installing MVC in previous versions of Visual Studio. If you're getting this error, you probably don't have the older versions of VS installed anymore.
So, installing the Microsoft.AspNet.MVC NuGet package will require Microsoft.AspNet.WebPages and Microsoft.AspNet.Razor, and the Microsoft.AspNet.WebPages includes System.Web.Helpers.dll.
If you've got direct references to System.Web.Mvc.dll and you don't want to use NuGet for MVC, you can get the Microsoft.AspNet.WebPages NuGet, or there are some other NuGet packages that only contain System.Web.Helpers.dll, like the microsoft-web-helpers or System-Web-Helpers.dllpackages.
There appear to be 2 versions of System.Web.Helpers.dll, one for .Net 4.0 and one for 4.5. Choosing the correct version of MVC or AspNet.WebPages will ensure you get the right one.
As for VS2017 I didn't find it in "extensions", there's a Nuget package called "microsoft-web-helpers" that seems to be equivalent to System.Web.Helpers.
I had the same problem , first I couldn't find those dlls in the list of .NET components . but later I figured it out that the solution is :
1- first I changed target framework from .NET framework 4 client profile to .NET framework 4.
2- then scroll down the list of .NET components , pass first list of system.web... , scroll down , and find the second list of system.web... at the bottom , they're there .
I hope this could help others
In VS 2010 just right click on project or on reference and click add reference.
On the popup window Select Assemblies - > Extensions -> System.Web.Helpers
Installing ASP.NET MVC3 from here should help.
On VS2017 I installed the NuGet package: Microsoft.AspNet.WebPages
That did the trick.
This particular NuGet package has a habit of losing its references in one of our projects. From time to time I will need to run the following command in the Package Manager Console to restore the references and everything is OK again
Update-Package Microsoft.AspNet.Webpages -reinstall
I had to install RazorGenerator.Templating to get it all to work. From the NuGet console, type:
Install-Package RazorGenerator.Templating
They should be under C:\Program Files\Microsoft ASP.Net (or C:\Program Files (x86)\Microsoft ASP.Net if you're on a 64-bit OS) in a subfolder for MVC3 or WebPages.
The issue is a missing or outdated version of MVC. I was running VS 2015Preview and could resolve the issue by installing the latest version of MVC via NuGet.
Just in case anyone is still coming across this one.
When you install this nuget package Microsoft.AspNet.WebPages they can be find in C:\Program Files (x86)\Microsoft Visual Studio\Shared\Packages\Microsoft.AspNet.WebPages.x.x.x\lib\net45
