The BITS Manager is a sample WPF C#/.NET utility to examine and control your BITS uploads and downloads

bits-manager's Issues

Registry key

I don't think that this was intended?

how to configure machine in local network to enable peer caching?

Make I ask how to enable peer caching in BITS? what configuration needed for the PCs in the local network? I expect to download files from other PCs just like windows update.

Application crashed after start quick download

Windows Server 2012R2
after add quick download job it's gave out some of COM exception windows, and then I found this in Apllication Events Log:

"Range" header missing in BITS download request randomly

I have implemented a web api server to handle BITS download requests according to this. At the server end, the first Get request header does not contain the key Range sometimes.

BITS keeps retrying and finally the job reaches Error-State. For smaller files ~2MB this works properly if entire file is sent in this case, but for file bigger files (~350 MB) BITS keeps retrying. Is it the expected behavior or BITS expects some other Response here?

The background access settings of the job's owner app prevent the job from transferring at this time

First and foremost, thanks for this managed sample, it was a great help to kick-start my BITS journey.

My app based on BITS-Manager and BITS-Manager itself worked great, but when I packaged my app with MSIX, things started behaving strangely. Every background copy job started from the packaged app transitions into the BG_JOB_STATE_TRANSIENT_ERROR state immediately and stays that way until the app is closed or becomes inactive/minimized. I was able to reproduce this issue with the BITS-Manager app in a packaged environment.

Using bitsadmin /list /allusers /verbose, I got this:

CUSTOM HEADERS: NULL

I tried to set the job's priority, but it didn't help. I also had a hunch that I might need to enable some capability in the MSIX manifest, but I haven't found anything. I also tried to use the BackgroundDownloader from my WPF app, but it looks like UWP only.

Is it a known behavior? Anything I can do to make it transfer bites while the packaged app is running? Thanks in advance 👍
