Hello, great question.
.indeox deployment is no longer supported, so I updated the documentation as follows
Direct Deployment {#zip-file}
An extension can be directly deployed to an Inedo product's extension root as a simple universal package.
To do for an extension named MyExample, first create a manifest file called upack.json with the following contents:
{
"name": "MyExample",
"version": "1.0.1"
}
Then, create a zip file called MyExample.zip with the compiled output in a package folder, and the upack.json at the root, like this:
/package/
/MyExample.dll
/SomeLibrary.dll
/upack.json
Rename the the zip file to MyExample.upack, and copy the .upack file into the Product extensions directory. By default, this will usually be in C:\ProgramData\«product-name»\Extensions, but you can verify the exact location by going to the Admin->All Settings page and looking for the ExtensionsPath value.
Finally, restart the product services (and application pool if hosting in IIS).
