C# SDK Framework
What version does our .Net Framework support?
We do not advise the client to use .NET framework if they will be using and installing our SDK as our SDK does not support most of the programming languages running in .NET.
We do advise them to use our REST API and still use programming languages. This will allow them to still do API calls without installing our SDK.
