Upon application startup the application currently picks a Random Delay time (1000-3000ms) before attempting to connect to each of its peer systems If Machine 1 attempts to Connec...

Need to upload file, and use it in the pre-init event

As it states, I need to upload a file, and then use it in the pre_init event of a second page. Server lifecycle prevents this (as pre_init happens before the event handlers), that's fine, so the only way I can see around is to use page1 to upload the file, then do a response.redirect to the page2 where I can use the file in the pre_init....

Will SqlConnection get disposed by GC?

The rest of the code should be deterministic and do using (...) { } (equivalent of try {} finally { Dispose(); }) to guarantee a cleanup as soon as possible. Also, the GC will not call Dispose(), so the recommended pattern is to override the Fin...

How does one implement Google Federated Login using dotnetopenauth

Run MSIs during install

I am looking to make an installer for a .net application which requires a few other MSI be run. Because of the restriction that you can only run one MSI at a time(honestly, is it 1995?) and my desire to provide configurability of which MSIs to run I can't just shove the MSIs in a bootstrapper as seems to be the recommend practice. I fo...
