Assembly Conflict in Newtonsoft.Json - asp.net

We are getting an assembly conflict after we updated Newtonsoft.Json. I am having trouble understanding where the specific version that is referenced in the error is coming from. There is nothing in the web.config that points to a specific version.
System.IO.FileLoadException: Could not load file or assembly
'Newtonsoft.Json, Version=3.5.0.0, Culture=neutral,
PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The
located assembly's manifest definition does not match the assembly
reference. (Exception from HRESULT: 0x80131040)
Would GAC-ing the two versions of the assembly work to solve the issue?

As #jammykam commented in marto's answer you can redirect the assembly. I have done this in the past with Newtonsoft and Sitecore without a problem. You can take a look at my Sitecore Content as Service code where I have it working.
You are specifically interested in these lines in the web.config file:
https://github.com/HedgehogDevelopment/sitecore-content-service/blob/master/Sitecore/Web/Web.config#L3499
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.0.8.0" newVersion="4.5.0.0" />
</dependentAssembly>

GACing them might work but it will create a maintenance nightmare. Don't do it!
I think you have 2 options:
Use the version that came with Sitecore which will depend on which version of Sitecore you are running.
Leave the one sitecore version untouched and use ilmerge to combine the Newtonsoft.Json version you need with your own assembly.
I would recommend 1 if you don't need any of the most recent features of the library like (dynamics... etc)

Newtonsoft.json dll issue in ssis

Can anybody help to resolve this.
I have added third party reference (Json newtonsoft) dll in my script component, but when i run the package through sql server agent, I am getting an error
Could not load file or assembly 'Newtonsoft.Json, Version=10.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The system cannot find the file specified.
I have registered the dll in gac and same dll (even same version) is also used in uat but while executing on prod it is getting failed.
Any suggestions?
Firstly I would check that the version in the web.config matches the version of the DLL. Right click on the newstonsoft.dll and go to details tab, product version.
You should then have a corresponding assembly identity in your web.config like
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json"
publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-10.0.0.0"
newVersion="10.0.0.0" />
</dependentAssembly>
Also if you have multiple projects in your solution then right click your solution, manage nuget packages for solution and go to the consolidate tab to check that you don't have multiple versions of newtonsoft
Finally resolved the issue-
The command to register DLL was having space before the DLL name. While registering through cmd it showed registering success however the folder was not created in gac_msil location I. E. dll was not registered.

Could not load file or assembly error (System.Web.Helpers)

When trying to run my project/website I get the error message:
Could not load file or assembly 'System.Web.Helpers, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
I don't know where the System.Web.Helpers is coming from it is not even referenced in my solution. I did a find all for System.Web.Helpers and on 3.0.0.0 and it found neither. Also this project is working for other people on my team on the same branch.
I've looked around the internet and tried a lot of the solutions. Running out of ideas.
For myself, I had to remove all <dependentAssembly> references to the DLLs being complained about from:
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
Once removed this issue was fixed. I also ensured MVC 3 and MVC 4 were installed via the Web Platform Installer

Project stops working after installing signalr

After I install signalr to my project and try to run the project I have this error message
Error message:
Could not load file or assembly 'Newtonsoft.Json, Version=4.5.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
How can I solve this problem.
After I search in the Internet for any solution, I didn't find any solution.
The only way that solve the problem is to install old version of signalr.
I install version 2.1.0. This version doesn't change the version of Newtonsoft.Json.
Thanks for all replies.
reinstall Newtonsoft.Json dll again, SignalR installs an old version of Newtonsoft.Json dll, and make sure that your web config file references the newer verion.
I think this is the error you meant (I remember encountering this as well but that was quite some time ago).
Try adding the following
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.1.0.0" />
</dependentAssembly>
under
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
....
in your hub's web.config file and try

Could Not load NewtonSoft.JSON after deploying MVC app to Azure

I've deployed a MVC 4.5 web site here
However, when I view the site in browser after deployment, I have to turn custom errors off to see the following error:
Exception Details: System.IO.FileNotFoundException: Could not load file or assembly
'Newtonsoft.Json, Version=4.5.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or
one of its dependencies. The system cannot find the file specified.
I ensured that CopyLocal is set to True for the DLL in my References folder. What other changes need to be made for a successful deployment?
I was having this same issue today and I'm not completely sure what I did to fix it. So I'll try giving a detailed walk through of my process.
I tried deploying a default app out of VS13 and it was too bombing with this message. FAIL.
I then removed the Newtonsoft.Json assembly and manually added the 5.0.6 version I needed. I also made sure CopyToLocal was set to true. FAIL. My sadness grows.
I enabled NuGet Package Restore. FAIL. My sadness turns to anger.
I deleted my Azure site in a fit of rage, recreated it, and the republished out again. SUCCESS!!!
So, the only logical(ish) answer I think I can give is to delete your Azure website, recreate it, and then publish again.
I hope this helps someone.
I fixed this problem by redirecting the assembly version from 0.0.0.0-6.0.0.0 to 6.0.0.0
by adding a depententAssembly in Web.config:
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<!-- Add these 4 lines to Web.config, under runtime/assemblyBinding -->
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
</dependentAssembly>
<!-- End of copy -->
</assemblyBinding>
</runtime>
<configuration>
You will find other dependentAssemblies there too, like System.Web.Mvc, WebGrease.
The newest version of Newtonsoft.Json is now 6.0.3. You may have to increase 6.0.0.0 later. Find the current newest version by looking at the version in the Solution Explorer. References -> Newton.Json -> (right click -> Properties) -> Version in the Property view
If you're sure CopyLocal is true, then the only other possibility is that you have project reference to a different assembly version than what's listed in your packages.config. Make sure the DLL version matches the version in the packages.config.

Add reference to .dll asp.net

I have a simple question about adding references to a .NET project. I'm adding reCAPTCHA to a website and i have downloaded the dll.
After setting the reference to the dll i build and run the project and gets this error:
[ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.]
System.Reflection.Module._GetTypesInternal(StackCrawlMark& stackMark) +0
System.Reflection.Assembly.GetTypes() +96
StarSuite.Core.Settings.GetSingletonInstancesOfBaseType(Type baseType, String staticMethodName, Type returnType) +149
[ApplicationException: Unable to load types from 'Recaptcha, Version=1.0.5.0, Culture=neutral, PublicKeyToken=9afc4d65b28c38c2'. LoaderExceptions: [FileNotFoundException: Could not load file or assembly 'System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.]
]
What am i missing, why do i get this error?
Sorry if the question is silly...Is it your web project MVC? It seems that If you're using web form based project you shouldn't use that component since it relies on mvc assemblies (maybe there is a web form version?).
File Not Found:
This is you reason - its in the output:
FileNotFoundException
Double check where your reference is pointing to
Have you added the DLL under references in your project so it will be included in the build?
For people finding this whilst searching for a fix for Umbraco, the fix can be found here:
http://our.umbraco.org/forum/developers/xslt/19383-referencing-catcha-dll-breaks-xslt
The same fix can be applied to websites that are not running Umbraco.
Summary to save you having to read the whole forum post, add this to your web config:
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35"/>
<bindingRedirect oldVersion="1.0.0.0"
newVersion="2.0.0.0"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
