I am using Newtonsoft.Json in my Windows Service project.
My Newtonsoft.Json version is 6.0.0.0 and I have it referenced in my Project's References.
Installation and compilation go through just fine. But when I start my service from Services it throws an exception:
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.
I also searched the web and added the following in my app.config file:
<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>
But still getting the same error.
What am I doing wrong?
If you are planning to convert array into Json, no need to use outsourced dll's. VS 2010 has JavaScriptSerializer to approach this task.
The example is as follows:
using System.Web.Script.Serialization;
JavaScriptSerializer js = new JavaScriptSerializer();
var json = js.Serialize(strYourArrayString);
Probably the problem is related to startup directory (is 'Newtonsoft.Json' in GAC?).
You can try to work on services to set the directory but I gave up.
Actually I set always copy local for non Microsoft referenced assemblies and I use a source code similar to this

I'm getting the following exception when trying to call GetDatabase method of the MongoClient class after adding a new configuration using VS config. manager:
Could not load file or assembly 'System.Buffers, Version=4.0.2.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
I installed the latest System.Buffer nuget package v4.5.1, created dependentAssembly in my app.config and Reference in my .csproj file, but I still have the same issue. For some reason it tries to reference System.Buffer with v4.0.2. Has anyone had a similar error and how did you solve it?
Could not load file or assembly 'System.Buffers, Version=4.0.2.0…'
Solution
1) use CMD(run as Administrator ) and type
cd xxxx(xxxx\packages\System.Buffers.4.5.1\lib\netstandard2.0))
run
gacutil /i System.Buffers.dll
Then, when you finish it, please run update-package -reinstall under package manager console to reinstall the package.
2) you can try to change Version=4.0.2.0 to Version=4.0.3.0 in csproj file.
Besides, there is a similar issue you can refer to.
The easiest way is to use Nuget package manager, downgrade system.buffers to any lower version, and then upgrade it to the latest again.
In my case, I had to add the assembly reference in the web.config that was already published in the Azure App Service, inside the <configuration></configuration> tag:
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="System.Buffers" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.0.3.0" newVersion="4.0.3.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
I ran into this issue when adding the Azure.Storage.Blobs package to a Class Library where I was attempting to create a blob uploader client. When I added the package, it created an app.config with the correct binding redirect:
<dependentAssembly>
<assemblyIdentity name="System.Buffers" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.0.3.0" newVersion="4.0.3.0" />
</dependentAssembly>
<dependentAssembly>
The issue, however, is that this binding redirect needs to live in the app.config of the application, not the class library: Can a class library have an App.config file?
So, adding the binding redirect is the correct way to solve this issue. Just make sure the binding redirect is specified in the calling web/console/etc app.
Another solution: just remove references to the assembly in the Web.config files of the projects generating the exception.
The references can look like:
<dependentAssembly>
<assemblyIdentity name="System.Text.Encodings.Web" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.0.4.0" newVersion="4.0.4.0" />
</dependentAssembly>
I ran into a similar issue, tried all the steps above. In the end, another project had an older version of the same library. Too many projects in the solution, the other reference was scrolled out of view.
The following error appeared after deploying the application to IIS, although it's NOT the first time to deploy this web application, but this is a new update to it!
Could not load file or assembly 'System.Web.Mvc(1)' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
It looks like you tried to install the ASP.NET MVC dependency twice since you have System.Web.Mvc(1) instead of plain System.Web.Mvc, so please take note of that. More than likely, that other assembly you are using is referencing the old dll, so make sure you have the right newVersion value under BindingRedirect in your Web.config file, as it should look something like this:
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35"/>
<bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="5.2.3.0"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
I have a application running on a windows server 2012 that was using Telerik.Web.UI.dll version 2014.1.403.45.
During the latest deployment the Telerik dll under /bin folder got updated with 2015.1.401.40.
Because of new dll some functionality stopped working.
When i replace the dll on server with older version i get following error
Parser Error Message: Could not load file or assembly 'Telerik.Web.UI, Version=2015.1.401.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies.
The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
I also tried to assembly binding
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Telerik.Web.UI" publicKeyToken="121fae78165ba3d4" culture="neutral"/>
<bindingRedirect oldVersion="2015.1.401.40" newVersion="2014.1.403.45"/>
<assemblyIdentity name="Microsoft.WindowsAzure.Storage" publicKeyToken="31bf3856ad364e35" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-2.1.0.4" newVersion="2.1.0.4"/>
</dependentAssembly>
</assemblyBinding>
I am still getiing the same error.
Is there any way to handle this without deplying the entire code again?
i got this type of issue, but in different case(in Unit Testing). for that I cleared the Bin. then did a build. then issue resolved for me.
Maybe there is a way, but I would redeploy. Build it again with the reference to the older version. That's the safest way and the best way to make sure all references point to the same assembly.
To be absolutely sure about the right references, set the dll to copy to local is true, and copy and replace it with the one on your server.
I'm trying to add Elmah to my MVC3 project. After installing via Nuget, when I try to access elmah (via localhost:port/elmah.axd), I get an error containing this:
Could not load file or assembly 'MySql.Data, Version=6.1.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d' or one of its dependencies. The system cannot find the file specified.
I've removed the mysql.data dll and added my own copy (version 6.4.4.0 - the documentation says you can override the dll provided with a newer version), but this error remains. Has anyone else encountered this?
My solution was to add this to my web.config:
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity
name="MySql.Data"
publicKeyToken="c5687fc88969c44d"
culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-6.4.4.0" newVersion="6.4.4.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>
This basically says to the compiler that whenever something requests a version of the MySql.Data assembly that's between versions 0.0.0.0 and 6.4.4.0, it should instead be supplied with the version 6.4.4.0 assembly instead.
I am trying to use JSON.NET and after including the .dll and trying to use one of the methods I get this error:
Could not load file or assembly 'Newtonsoft.Json.Net35, Version=4.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The system cannot find the file specified.
Any know why I might be this error?
Two things to check:
(1) You may have to "Unblock" the DLL. By default, when you download a .zip file from the Internet, that file, and all .dll or .exe files extracted from that .zip file, are given a file system attribute that prevents them from loading and executing. Right-click on the DLL in Windows Explorer, choose "Properties", and in the resulting dialog box click on the "Unblock" button. Or better yet, do that for the .zip file, and then re-extract all the files.
(2) The Newtonsoft JSON.NET library comes in five flavors: one each for .NET 2.0, 3.5, 4.0, Silverlight, and Windows Phone. You need to use the right one for your particular environment. I presume that this is a .NET 3.5 project?
In my case, I resolved this problem once I realized that a library that I was using was itself using the Json.NET but with the earlier version (3.5). Linking the second library to the new Json.NET version solved the issue.
Hope this helps.
You need to download release 1 instead of release 2 of the Newtonsoft.Json.
