You want to embed some UserID-marker in your excutable/class library, before it gets downloaded and installed?

Eddy Vluggen wrote:

approach would be to compile a personalized version, build and create a setup, prior to downloading.

Eddy Vluggen wrote:

When you start your executable;
- Check if your classlibrary is in place, if not:
- Start the download of the class-library (from code, or manual)
- The WebApp gets requested to download a file, compiles the classlib with the embedded string and push the generated file.

I'll try to build a small prototype to do this thing, might take a while
