SOLUTION

The best long term solution is to switch to using REST instead.

Until you have switched to REST please edit web.config which you find under C:\GpsGateServer\IIS. And add the following inside the <configuration> tag.

 
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30AD4FE6B2A6AEED" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-9.0.0.0" newVersion="10.0.0.0"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
