Can Wix accomodate an external C# website?

Find a good → C# to → JS-Converter and perhaps than you will be able to reconstruct your C#-site, but i am not sure.

What exactly do you mean by “accommodate”?

If you want the Wix site to access the external C# site, you can use the wix-fetch API . If you want the C# site to access the Wix site, you can expose a site API using HTTP functions .
