re: Large Object Heap Improvements in .NET 4.5

@Mickey,

What .NET Framework version do you use? Do you still have the high fragmentation problem when running on .NET 4.5?

Its quite remarkable that something mature such as the .Net platform has such a fundamental issue. What are the guys at MS doing? I mean its all very well to race ahead, but if you've got a weakness in the foundations then surely before you add extra levels sort out the foundations.

I've started work at a company here where they regularly have to recycle their app pools, and I've tracked this down to large amounts of memory being allocated due to fragmentation. Specifically: 165MB allocated of which 90MB were free but due to fragmentation 20MB was the biggest memory fragment available.

still searching for a workaround as not convinced that the object pooling will work here.

This is awesome stuff - I can't remember the last time I installed a framework and had so many "are you serious???" moments.

Very cool - keep up the good work!

Hello,

After installing VS2011, our application is NOT working anymore on PC with .NET 4.0.3. (even if we are targeting .NET 4.0 in VS)

Framework 4.5 is NOT fully backward compatible with 4.0 !

* We can't use .NET 4.5 as our application must be supported under Windows XP.

* We can't reproduce the crash on our development PCs as VS2011 replaced .NET 4.0 files.

What can we do ?

Thanks for your help

Finally got past an issue attaching to a running process! I'm not seeing any stack traces in the managed threads though.

This is great! I can see this going pretty big in just overall debugging.

I still seem to be getting the "unable to attached to pid" error, though. Of course, I've only tried on the calc, notepad, and issexpress processes.

Keep up the awesome work!
