Question: How do I create all the ASP.Net tables, sprocs etc in a database that already has data (non conflicting) in it.

Answer: 
If you have access to the database, run the following commands in command line:

```
cd "C:\Windows\Microsoft.NET\Framework\v2.0.50727"
aspnet_regsql

```

That will start a guide that will help you add all the tables and sprocs to any table you can access from that computer.
This should help you:
