Problem: I want to deploy modified code into web server. web server is having IIS version set to V2.0. and now I have developed and published code on my local machine with version 4.0. (there is App_code.dll as part of all dll files).
Now whenever I am deploying all files along with App_code.dll I am getting following error:"
Could not load file or assembly 'App_Code' or one of its dependencies.
This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded"
1) My question is how do I build App_code.dll in older version.
2) I tried changing target framework to V2.0 while publishing but then its not working because AJAX functions from other dll are not compiling..
can anyone please suggest what to do to run the site..
Help is appreciated.
Thanks
Sorry about the answers I've given... But try this...
Try adding <codeBase> elements to the application config file to specify the exact location of each dll, and the version of .Net it requires. Apparently this works because <codebase> is checked BEFORE the probing heuristics kick in each time an assembly needs to be loaded.
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="sharedlibA" culture="neutral" publicKeyToken="..." />
<codeBase version="1.0.0.0" href="bin\sharedlibA.dll" />
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="sharedlibB" culture="neutral" publicKeyToken="..." />
<codeBase version="1.0.0.0" href="bin\sharedlibB.dll" />
</dependentAssembly>
</assemblyBinding>
</runtime>
If that doesn't work try this.
Late answer but, I'm writing this for future viewers.
I had same error after publish the application to the Server.
I figure it out doing like this.
While publish there is configuration in Setting.
In publish section there is option called
Precompile during publishing
you have to check the checkbox and save then Publish. This will takes your code files .vb/.cs and converts them into a compiled DLL files.
In my case it was unchecked.
I've just uploaded a Asp.Net Web Api 2.2 project to production server and I got the error stated in the title.
In my Web.config I already have this:
<dependentAssembly>
<assemblyIdentity name="System.Web.Http" publicKeyToken="31bf3856ad364e35" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-5.2.2.0" newVersion="5.2.2.0" />
</dependentAssembly>
The file does exist in the bin. What would cause this?
All my Asp.Net Web API files are up to date and show 5.2.2 as the version. It works fine on my dev machine.
Set Copy Local to true in the properties for the System.Web.Http and System.Web.Http.WebHost assemblies and redeploy the package.
If this doesn't solve your problem completely try reinstalling the NuGet package. This will hopefully correct broken dependencies. From the package management console, run this command:
Update-Package Microsoft.AspNet.WebApi -reinstall
Make sure to install System.Web.Http.WebHost as well.
For me, from "Solution Explorer" I checked the ver of "System.Web.Http" in the project references, which was 5.2.3.0 so, in the web.config, I changed:
<bindingRedirect oldVersion="0.0.0.0-5.2.2.0" newVersion="5.2.2.0" />
to
<bindingRedirect oldVersion="0.0.0.0-5.2.2.0" newVersion="5.2.3.0" />
then build. It worked for me!
Adding below config inside web.cofig solved my issue.
<dependentAssembly>
<assemblyIdentity name="System.Web.Http" publicKeyToken="31bf3856ad364e35" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="5.2.5.0" />
</dependentAssembly>
If you have an assembly in GAC with a different version, it will always be loaded, not the one from bin folder.
Make sure you are referring the correct version of System.web.http in
your project (check web.config).
If System.web.http is not present in reference, try to install it
using nugets.
If both the above points are correct at your local then try to restore your nugets from
package manager console
I ran into the same exact error. It was caused by a script I was using to deploy the application which replaced the Web.config with a previous version. The Web.config was specifying the wrong version of System.Web.Http. Removing that step solved the problem.
I solved the problem into the following steps:
Stopping the site into the remote web server
Cleaning the site folder
Publishing it again
Starting the site
One click publishing did not replace the correct version of dll or the remote site was keeping the file in use.
Silly advise, but in my case restart Visual Studio helped me.
Another way to do this, which do not require a New build or update/reinstall With Nuget is to do the following in config.web:
For the dll you have issues With, do the following:
<bindingRedirect oldVersion="0.0.0.0-65535.65535.65535.65535" newVersion="5.2.2.0">
I had an issue today, and this little tweak solved it...
I am getting the Error
System.IO.FileLoadException : 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)
for my CI build
Solution which I tried
<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>
It also did not work
In package manager console execute: Update-Package –reinstall Newtonsoft.Json.
UPDATE
I originally posted this as a comment but as #OwenBlacker suggested I'll just put it here:
If you still get an error after doing this, then what worked for me eventually is that I deleted Json.Net's <dependentAssembly> section from my .config file. Reinstall brings it back if it's not there and apparently you need to delete it. Until there will be a normal solution in the package itself, I'm afraid this manual step is a must.
Note: Please read the comments below before doing this.
As per René's comment below BE AWARE that the command posted in the answer will reinstall the package in every project in your solution. So if you use the Newtonsoft.Json package in several projects and maybe use different versions, just executing the above command might have unwanted consequences.
To everyone having problems with Newtonsoft.Json v4.5 version try using this in web.config or app.config:
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<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>
</assemblyBinding>
</runtime>
IMPORTANT: Check that the configuration tag of your config file has no namespace attribute (as suggested in https://stackoverflow.com/a/12011221/150370). Otherwise, assemblyBinding tags will be ignored.
The key point is referencing right version in your config file.
Steps;
1- look at what is the version of your Newtonsoft.Json.dll in the project reference property what ever the version in your package folder (For example mine is 7.0.1 and the reference Version is 7.0.0.0)
2- look at what the project expect from you in the exception (mine is 6.0.0.0)
3- Add dependent assembly to your config file as it should be..
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30AD4FE6B2A6AEED" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="7.0.0.0"/>
</dependentAssembly>
I had no luck with any of the solutions presented here (uninstalling, reinstalling, deleting references, creating bindingRedirects etc.) I had to go back to an old version of Newtonsoft. Version 5.0.6 had been working before, so I tried that one. I had to enter these two commands in the Package Console:
uninstall-package newtonsoft.json -force
install-package newtonsoft.json -version "5.0.6"
The -force option in the first command is required to force the uninstall. Dependencies with other assemblies prevent the uninstall without it.
I fixed the problem adding this binding redirect to my .config file:
<runtime>
. . .
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed"
culture="neutral" />
<bindingRedirect oldVersion="4.5.0.0" newVersion="6.0.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
The error message complains about not finding version 4.5.0.0, the current version of Newtonsoft.Json is 6.0.0.0 so the redirect should go from 4.5 to 6.0, not viceversa
I think you are pointing to the wrong target, change it to 4.5 instead of 6.0
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed"
culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="4.5.0.0" />
</dependentAssembly>
This should work.
I've spend couple of days trying to resolve this frustrating issue. I've tried pretty much everything that can be found on the web. Finally I found that this error could be caused (like in my case) by the different target .Net project versions (4.5 and 4.5.1) in one solution. The steps bellow fixed it for me:
Double check the .Net version of every project that's in your solution. Just right click on project and go to Properties.
If possible set the same .Net version for all projects. If not at least try to change the Startup project one (for me this was the one causing the issues).
Remove all Newtonsoft.Json packs from the solution.
uninstall-package newtonsoft.json -force
Update all Newtonsoft.Json versions in all packages.config files, like so
<package id="Newtonsoft.Json" version="7.0.1" targetFramework="net451" />
Reinstall Newtonsoft.Json from "Package Manager Console" with:
install-package newtonsoft.json
Rebuild the solution
(Optional) 7. If you changed the Startup project, return it again
uninstall-package newtonsoft.json -force
install-package newtonsoft.json
Did the trick for me :)
if you using multiple project in same solution
and library of the one other
check is all projects has same version of Newtonsoft.Json
Remove the Newtonsoft.Json assembly from the project reference and add it again. You probably deleted or replaced the dll by accident.
I was writing a WebApi REST service client, so for me this error was caused by adding References to the System.Net.Http and System.Net.Http.Formatting assemblies manually via Add Reference, when I should have added the Microsoft.AspNet.WebApi.Client package via NuGet.
See also this answer to another question.
You have 2 different versions of JSON.NET library in your solution. To solve this you should upgrade them to latest version. Follow these steps:
1-Open solution explorer
2-Right Click on solution name
3-Select Manage Nuget Packages for Solution
4-Select Updates from menu
5-Update JSON.NET package
This will resolve your issue.

Could not load file or assembly 'Newtonsoft.Json, Version=7.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies
Deploy the correct version to the CI machine
This is telling you that the assembly loader found a different version of the Newtonsoft.Json assembly, that does not match the reference you created in your project. To load the assembly correctly, you must either deploy the assembly side by side with your compiled code, or install the correct version of the assembly in the destination machine (i.e. in the GAC).
Alternative: make sure the configuration is in the correct file
If you want to keep the current solution, and load an assembly with a different version, make sure that the configuration you posted is in the correct .config file. Remember that there is no xpto.dll.config, a DLL loaded by an application always uses the config file of the running application.
Normally adding the binding redirect should solve this problem, but it was not working for me. After a few hours of banging my head against the wall, I realized that there was an xmlns attribute causing problems in my web.config. After removing the xmlns attribute from the configuration node in Web.config, the binding redirects worked as expected.

Works for me.... just put the version you are using in newVersion i.e(newVersion="7.0.0.0")
I was getting same error and by adding below code error resolved on production.
Answer is too late but might help someone.
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-12.0.0.0" newVersion="12.0.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
Close solution.
Open packages.config and *.csproj with text editor and delete any line have Newtonsoft.Json
Ex:
<Reference Include="Newtonsoft.Json,Version=9.0.0.0,Culture=neutral,PublicKeyToken=30ad4fe6b2a6aeed, processorArchitecture=MSIL">
<HintPath>..\packages\Newtonsoft.Json.9.0.1\lib\net40\Newtonsoft.Json.dll</HintPath>
<Private>True</Private>
</Reference>
Or
<package id="Newtonsoft.Json" version="9.0.1" targetFramework="net40" />
Open solution again and re-install Newtonsoft.Json by Install-Package Newtonsoft.Json
It work for me.
We had the exact same issue that you mentioned. We're using nunit to run tests through CI, and we have nunit running a file called tests.nunit, which describe a list of test dll fixtures to run.
Each test fixture had their own config file, but when run through the "tests.nunit" file the binding redirects seem to be ignored. The solution was to add the binding redirects to a new config file, "tests.config" that was beside the "tests.nunit" file.
I have got the same type of problem. And I also solved it just doing the following:
Go to TOOLS > NuGet Package Manager and Select Package Manager Console. Finally, execute the following two commands :)
uninstall-package newtonsoft.json -force
install-package newtonsoft.json
You should update the web.config file in the server.
When nuget install NewtonSoft update this file including this code
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<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>
</assemblyBinding>
Just check the version of Newtonsoft.Json Newtonsoft properties
Then you need to add that version in your web config (in my case 8.0.0.0)
Web config
I made the mistake of adding a NewtonSoft .dll file for .Net 4.5.
My main project was 4.5, but when I added an extra project to my solution, it strangely added it as a .Net 2.0 project... and when I attempted to use NewtonSoft's 4.5 dll with this, I got this "Newtonsoft.Json couldn't be found" error.
The solution (of course) was to change this new project from .Net 2.0 to 4.5.
I was facing the same error and struggled with it for hours. I had a web API project which is using Newtonsoft.json and another UnitTest project for the web API project. The unit test project also needed the Newtonsoft.json reference. But on adding the link I was getting the above exception.
I finally resolved it by adding the below code snippet in the app.config of the unit test project:
<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>
In my case, the main project was still referencing an old version of Newtonsoft.Json which didn't exists in the project any more (shown by a yellow exclamation mark). Removing the reference solved the problem, no bindingRedirect was necessary.
I had the exact same problem with version 7.0.0.0, and the lib causing my problem was Microsoft.Rest.ClientRuntime which somehow was referring to the wrong version (6.0.0.0) of Newtonsoft.json, despite the right dependency management in nugget (the right version of newtonsoft.json (7.0.0.0) was installed).
I solved this by applying the redirection above from 6.0.0.0 to 7.0.0.0 (from Kadir Can) in the config file:
<bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="7.0.0.0" />
----> After a few days without changing anything it came up again with the same error. I installed version 6.0.0.0 n updated it to 7.0.0.0 it works fine now.
Reinstall newtonsoft package through nuget did not worked for me.
I had to manually call JsonConvert.DeserializeObject to bypass this issue
I changed
HttpResponseMessage response = await client.GetAsync(url));
response.EnsureSuccessStatusCode();
MyObject data = await response.Content.ReadAsAsync<MyObject>();
For
HttpResponseMessage response = await client.GetAsync(url));
response.EnsureSuccessStatusCode();
string jsonStr = await response.Content.ReadAsStringAsync();
MyObject data = JsonConvert.DeserializeObject<MyObject>(jsonStr);
In my case, after downloading the assembly and adding the reference to the project, I solved this by 'unblocking' the DLL before adding the reference to the project.
Using Windows explorer, browse to the DLL location, right-click on the DLL and then select 'properties'. You'll find an 'unblock' button on one of the tabs and then you can add the reference and the assembly will load correctly.
Nothing from above helped me, but what actually fixed it is the following:
Remove all dependency bindings in app.config (from all app.config files in the solution)
Execute the following command from "Package Manager Console"
Get-Project -All | Add-BindingRedirect
Rebuild
Reference:
http://blog.myget.org/post/2014/11/27/Could-not-load-file-or-assembly-NuGet-Assembly-Redirects.aspx
Right click your project select manage Nuget packages, type newtonsoft in the search box and install the latest version. Then Run your App
Another insidious problem is that it appears that binding redirects can just silently fail if the element has an incorrect configuration on any other dependentAssembly elements.
Ensure that you only have one element under each element.
In some instances, VS generates this:
<dependentAssembly>
<assemblyIdentity ...
<assemblyIdentity ...
</dependentAssembly>
Instead of
<dependentAssembly>
<assemblyIdentity ...
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity ...
</dependentAssembly>
Took me a long time to realise this was the problem!
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.
