Hi Rick,

Once I added the vfp9.exe.config file into my VFP directory with the following content:

<?xml version="1.0"?>
<configuration>
  <startup>   
	<!-- <supportedruntime version="v4.0.30319"/> -->
	<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
	<!-- supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" -->    
    <!-- supportedRuntime version="v2.0.50727"/ -->    
  </startup>
  <runtime>
      <loadFromRemoteSources enabled="true"/>
  </runtime>
  
  <runtime>    
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-11.0.0.0" newVersion="11.0.0.0" />
      </dependentAssembly>
	</assemblyBinding>      
  </runtime>
</configuration>

I got it working correctly.

Now, I'm going to use the dll called MyDllName.dll to run my .NET library. Does it mean I need to add that config named MyDllName.dll.config with that content?

Thanks.
