One of the hidden gems (in my mind, but then I’m biased) in the Microsoft “Oslo” SDK that went public at PDC is the “M Script Mode” in Intellipad which we affectionately know as MrEpl. MrEpl is a REPL processor for the MSchema language and is a great...

In the last couple months I have had more fun playing with MGrammar than just about any other programming I’ve ever done, but in its current form the one thing that really feels missing to me is an easy ability to create CLR object instances. MGrammar...

My blog has been a little quiet in the last year or two after I left the CLR and went to work for Doug Purdy’s ( http://www.douglasp.com ) team in the Connected Systems Division. Since then I’ve been having amazing amounts of fun and working on lots of...

So, I haven't posted in quite a while, I need to get on that... In the meantime I've moved on from the CLR team after about 5 years of fun times and am now having fun exploring some new stuff that unfortunately I can't talk about... However, the peers...

http://blogs.msdn.com/patrick_dussud/default.aspx Patrick is super-smart... Hopefullly his blog will pick up where Chris Brumme's left off a couple years back. -josh

Other companies have much talked about 20% time... That sounds great to me! Here at Microsoft (at least in my group) we do too, kinda. I find that every one of my peers has some interesting project that they're working on outside of their normal work...

So, Rico beat me to the punch: http://blogs.msdn.com/ricom/archive/2006/08/03/688019.aspx As we have seen in the previous entry it is nice that the VSTS Profiler team has provided a tool which converts their .VSP files into something which is more easily...

I have spent the last couple years investigating the performance of various parts of the CLR and managed code, in that time I have learned that a profiler is an invaluable tool. There are quite a few profilers available including: CLR Profiler, Intel...

I just found out that VSTS has a free 180-day trial edition. http://msdn.microsoft.com/vstudio/products/trial/ This is AWESOME because VSTS has a great profiler included in the package!

Here's the guts of a response that I posted a while back to an internal mailing list re: tradeoffs of runing your managed code as 64-bit vs 32-bit. YMMV, and I'll remind you that every perf question has a thousand answers depending on the situation. >>>>>>>...

Check out this blog entry ( http://blogs.msdn.com/jkeljo/archive/2005/08/11/450506.aspx ) to see some information that is rather interesting to people writing managed profilers, and probably not very interesting to everyone else.

I’ve received a number of queries as to why the 64-bit version of the 2.0 .Net runtime still has array maximum sizes limited to 2GB. Given that it seems to be a hot topic of late I figured a little background and a discussion of the options to get around...

Lately we’ve seen a spate of issues coming up on 64-bit platforms within the Developer Division around usages of P/Invoke signatures which declare a parameter as type “byref byte” where the developer really means “byte[]” (the corresponding native parameter...

In previous blog entries I’ve spent some time talking about how to mark assemblies as bit specific and how the loader deals with those markings. What however is the preferred mode of an application? I will posit that it is to be compiled agnostic and...

I am forced to admit that this is one damn fine notebook. Thanks to the helpful instructions on Volker's blog ( http://blogs.msdn.com/volkerw/ ) I was able to get it up and running with 32-bit and 64-bit OSes very quickly. I'm currently trying to live...

In a number of blog entries I have discussed how on 64-bit machines .Net applications can run as either 32-bit or 64-bit processes depending on how the exe is produced. Generally it is highly recommended that developers use the compiler options provided...

[updated 10:50am 5/2/05: It turns out that I copied and pasted an error in my code from the newsgroup posting I was answering. However a kind reader was able to spot it and I've fixed it, I'm getting new data and will updated graphs later today, however...

[fixed typo: 9:37am] I received a question about this recently, so i figured i'd elaborate here with a little example... Let's assume we have the following three dlls: anycpu.dll -- compiled "any cpu" x86.dll -- compiled "x86" x64.dll...

Last night I played with Paint.Net for a while and got it running on the native 64-bit CLR with whidbey... Pretty cool stuff!!! Actually, a while might be overstating things... It took longer to install a copy of VS 2005 on my clean AMD64 machine than...

I just ran across these, they are a couple of really good reads on the .Net GC... http://blogs.msdn.com/maoni/archive/2004/06/15/156626.aspx http://blogs.msdn.com/maoni/archive/2004/09/25/234273.aspx

Here are a couple of really worthwhile entries written by Junfeng on the GAC, why you might compile platform specifc and 64-bit... I don't know if I need to bother with my intended GAC entry anymore... http://blogs.msdn.com/junfeng/archive/2004/08/11...

[10/15, 2:04pm, fixed a couple typos; 10/15, 4:51pm, clarified a point] Before you read this entry, you might want to read these two entries: - http://blogs.msdn.com/joshwil/archive/2004/03/13/89163.aspx - http://blogs.msdn.com/joshwil/archive/2004/03...

I was just playing around with some stuff at home where I was wishing that we had compile time attributes, it looks like XC# supports what I was looking for, I'll have to play with it a bit to be sure... http://www.resolvecorp.com/Products.aspx
