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 am adding a Web Reference in my website. Reference is added successfully. But when i add namespace in my webpage it give me following error.
Error 22 Reference.svcmap: Could not load file or assembly
'Newtonsoft.Json, Version=6.0.0.0, Culture=neutral,
PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The system cannot
find the file specified. App_WebReferences/FaxService/
Namespace name I give to my web reference is "FaxService".
In pages.aspx.cs page I have added
using FaxService;
What I have tried.
1) Removed web reference and add it again.
2) Update web refernce
3) Uninstall newton soft from "Pakage Manager Console" and removed all the dll's of newtonsoft from my solution.
PM> UnInstall-Package Newtonsoft.Json
4) Installed newton soft again through "Pakage Manager Console".
PM> Install-Package Newtonsoft.Json
5) Adding following lines in web.config
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-7.0.0.0" newVersion="7.0.0.0" />
</dependentAssembly>
</assemblyBinding>
This web reference is not newly added. It was working fine before.
Error says about Version=6.0.0.0, try to find where is reference to it? But your web.config uses 7.0.0.0. Try to find reference to 6.0.0.0 and delete it.
My thoughts are:
- maybe one of dependencies of it was updated and now it cannot be loaded?
- use option "DELETE ALL" before deploy, maybe something old is there in deployment directory.
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.
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)
I have a bit of a weird problem.
I developed an app with MVC 4 and the new Web API and it works fine locally.
I installed MVC4 on the server and deployed the app. Now I get the following error:
Could not load file or assembly 'System.Net.Http, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in
Funny enough, the version of System.Net.Http that I locally have either in my package folder or in the ASP.NET MVC 4\Assemblies folder is 1.0.0.0.
I actually removed the reference to System.Net.Http from my project, but I still get the same message. I'm a bit confused about where it gets the 2.0.0.0 reference from and why it would work locally but not on the server.
Looking at the nuget dependencies:
ASP.NET WEb API Core Libraries (Beta) depends on System.Net.Http.Formatting.
And System.Net.Http.Formatting depends on System.Net.Http.
I guess that is where this comes from. But I do have Version 2.0.20126.16343 of this package installed, it's just that the dll inside has version 1.0.0.0
Am I missing something?
UPDATE:
This is a sub-application of another ASP.NET app, but the other one is still based on WebForms. So, something is getting messed up. But if I do a clean under the assembly section in the web.config if does not even find the app itself anymore.
I had the same error while deploying previously converted (from .NET 4.5 to 4.0) web app on IIS 6.0.
In the web.config runtime section I've found
<dependentAssembly>
<assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0"/>
</dependentAssembly>
which I've changed to
<dependentAssembly>
<assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-1.0.0.0" newVersion="2.0.0.0"/>
</dependentAssembly>
Now works like charm.
I had the same problem with deployment my app to appharbor. The problem it does not support .NET 4.5 yet. What I did.
Switched my project to .NET 4.0 profile.
Uninstalled Web API NuGet package.
Installed Web API (Beta) NuGet package again.
Verified that .csproj file contains for ALL referenced assemblies, so it will always take it from Bin folder, instead of GAC.
Mine worked with:
Note the redirect of 1-4 to 2.0
<dependentAssembly>
<assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="2.0.0.0"/>
</dependentAssembly>
In your project's References folder there should be a reference to this dll, and the version should be 2.0.0.0. Make sure this is set to Copy Local = true. And then make sure it finds its way to your server app's bin folder.
This is one of the libraries that is now managed by nuget. So open Nuget and make sure everything is up to date. And in your projects packages directory the file should be here:
\packages\System.Net.Http.2.0.20126.16343\lib\net40
You could also try creating a new MVC4 app and see if the file shows up for that one.
In my case I fixed it in a much easier way, just give a HintPath to the reference to the nuget package:
<Reference Include="System.Data.Entity" />
<Reference Include="System.Net.Http, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">
<Private>True</Private>
+ <HintPath>..\..\packages\Microsoft.Net.Http.2.0.20710.0\lib\net40\System.Net.Http.dll</HintPath>
</Reference>
<Reference Include="System.Net.Http.WebRequest, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">
<Private>True</Private>
+ <HintPath>..\..\packages\Microsoft.Net.Http.2.0.20710.0\lib\net40\System.Net.Http.WebRequest.dll</HintPath>
</Reference>
<Reference Include="System.Numerics" />
<Reference Include="System.Security" />
In my case I unintentionally added a dependency to System.Net.Http version 2.1.10.0 through NuGet. I couldn’t get rid of it in the NuGet Package Manager (because other packages seemed to be dependent on it). However those packages aren’t dependent on this particular version.
Here's what I did in order to get rid of it (you can also use the NuGet console instead (using the –force parameter):
Change version of Microsoft.Net.Http in packages.config from 2.1.10.0 to 2.0.0.0
Uninstall BCL Portability Pack in NuGet Package Manager
Manually get rid of dependent libraries (System.Net.Http.* which have version 2.1.10.0)
Add a reference to System.Net.Http 2.0.0.0
In file config I deleted dependent Assembly:
<dependentAssembly>
<assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="2.0.0.0"/>
<dependentAssembly>
Now it works fine.
I was facing this issue on a test server (Windows 2008 R2) which was supposedly "ready" for deployment ;)
The hint was that when I checked the versions of System.net between my DEV machine and deployment server, they did not match.
Fixed using the steps below:
Downloaded .NET Framework 4.5 Standalone installer from HERE
Ran the installer on the deployment machine
Post installation of the framework, server wanted a reboot, so did that and volla! We are good to go!!
We are using VS 2013, created a new MVC 4 Web API and had a problem with the system.net.http.dll not being the correct version when built on our TeamCity server but it builds fine on our local developer machines that have VS 2013 installed.
We finally determined the problem.
When creating a new MVC 4 Web API and choosing the framework 4.0 on project creation we found the the correct NuGet package version for DLL was being put in:
..\packages\Microsoft.Net.Http.2.0.20710.0\lib\net40\System.Net.Http.dll
However the .csproj file for this project said the path for this system.net.http.dll file is:
..\packages\Microsoft.Net.Http.2.0.30506.0\lib\net40\System.Net.Http.dll
So when the build is attempted is fails on this path difference but is finding the correct framework version of the file elsewhere on the developer machine but not on our TeamCity build server.
So far this is the only difference we found. Changing the path in the .csproj file and building on local Dev machine with VS2013 still works find.
Checking that into version control and having our TeamCity build server (without VS 2013 installed locally) now finds the correct version of the .dll in its NuGet package folder for the solution and builds successfully rather than searching for another version of system.net.http.dll and finding a newer version which doesn't match the framework hence causing build failures.
Not sure if this helps.
Check your project file path for the DLL and make sure it matches your package folder path for the DLL.
Just simplifying the other answers for what worked for me.
I went to the NuGet manager, uninstalled the related packages (In my case, "Microsoft ASP.NET Web API 2.1 Client Libraries" and "Json.NET") and reinstalled them. Just took a few clicks.
Close the project, Open it again. Then, Clean Solution + Build. Works for me
For version 2.2.15.0, I did this:
<dependentAssembly>
<assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="2.2.15.0"/>
</dependentAssembly>
I had this exact same issue! I took a look at my Warnings tab in VS and noticed that one of my nuget packages was INDIRECTLY referencing .NETFramework Version 4.5.0.0. I had to uninstall this package and then reinstall the 4.0 version but be sure to specify the package versions that support 4.0(it'll default back to 4.5 i believe if you don't specify when installing the package). Hope this helps!
We had this happening on a server after deployment. It was caused either by:
A) Old files in the bin folder still hanging around that ought to have been deleted
or
B) Not having read access to the folder for the Application Pool Identity user.
In other words, for us this was resolved by fixing permissions on the folders for the site and wiping out the bin folder and redeploying.
I had the same issue with Gembox.spreadsheet.dll version 31.
" Could not load file or assembly 'GemBox.Spreadsheet,
Version=39.3.30.1095, Culture=neutral,
PublicKeyToken=b1b72c69714d4847' or one of its dependencies. The
located assembly's manifest definition does not match the assembly
reference. (Exception from HRESULT: 0x80131040) "
I tried almost everything from these articles and none of them worked. It just got fixed with simple step.
I tried building individual projects that basically set up the correct version reference to the dll and the error was entirely gone from the solution.
Go a similar issue and the directive mentionned in many comments worked fine
<dependentAssembly>
<assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="2.0.0.0"/>
<dependentAssembly>
Although, you have to ensure the old version coverage is high enough otherwise newer versions may not be redirected to the specific version you need and location using that newer reference won't work properly since the older reference is already in the bin directory.
For this error (and similar) it's worth going through NuGet Consolidate (Solution > Manage NuGet Packages...) to ensure the same referenced component versions are consistent in each class library referenced in the solution, since even a slightly older version may have dependencies on other older components. It's straightforward to use in conjunction with Updates and can save a lot of pain.
This solved this issue for me and I would say it's a must to get familiar with if you're creating helper libraries that also reference MVC or other web-based NuGet components.
