Wrote an application using the Newtonsoft.Json library. When you try to launch an application from Visual Studio 2015 or 2013, everything works, when you try to run on three different PCs (different versions of Windows and different system digits) outside the VS environment, everything works, but when you try to run on two different computers (they were ordered from different hosting providers) VPS KVM with Windows Server 2012 R2 x64 (.NET Framework installed) - the application cannot load the Newtonsoft.Json.dll library. The problem arises only with this library. I tried to add the library to the resources and upload them to them - the effect is the same. If you remove parts of the code responsible for working with JSON from the application (that is, remove the use of the library itself), then everything works fine everywhere.

Below is the error that occurs during startup:

Such an error may be in case you have built a project with AnyCpu, while some of the connected libraries are built with x86 \ x64.

How to solve this problem can be found here: https://stackoverflow.com/questions/270531/how-to-determine-if-a-net-assembly-was-built-for-x86-or-x64

I also recommend checking the version of the .net framework and checking the runtime version in the config:

 <startup> <requiredRuntime version="v4.0.20506" safemode="true"/> </startup>

Also check the bindings:

 <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-xxxx" newVersion="xxxx" /> </dependentAssembly> </assemblyBinding> </runtime>

    The answer above did not help me at all (probably because I have Sharepoint 2013, and not a separate application), it turned out that it only cost to add the assembly to the global assembly cache:

     gacutil -i Newtonsoft.Json.dll

    The gacutil utility should be called from the Developer Command Prompt in the Visual Studio folder.
