Longhorn GUI framework runs on XP!


Recommended Posts

Source: http://www.dotnetguru.org/blogs/sami/index.php?m=200312#4

After many weeks trying to work with the duo avalon+indigo on longhorn, i finally decide to move all PDC bits and Avalon APIs on XP. According to Microsoft, it is impossible, Avalon only run on LH. But believe me, longhorn is horribly laggy and it is more convenient for me (and most people) to use one laptop instead of multiple box just for hosting avalon applications. In addition, those who want to demo or test Avalon would prefer to host it on XP.

So, i start a long tough task trying to port Avalon samples on XP, and you know what ? i finally succeed ! There are no words to explain how it's fantastic to see a Xaml GUI running in XP. Avalon perform better on XP than LH and there is no blocking issue, animation work great, codecs also, ... Now i come up with the big question : can i publish my work tru an article or Microsoft discourage such a thing ?

well i'd publish it and see what they say

from avalons architect, since it has been quoted that over in the lh forum:

One of the big new changes that isn't yet in the Longhorn builds is the new video driver model. Once that goes in, you really won't be able to run Avalon on XP. In addition when the desktop composition stuff gets turned on (it wasn't in the PDC handout build) there will be a tight dependency between Avalon and the Longhorn User32.

Here as promised a small report of the manips that I had to carry out to do to work the stupid Avalon on XP. ?First of all, I left principle that the two environments LongHorn (LH) and XP were at the same level side build of the CLR. ?The two possessed in fact the v1.2.30703. ?Suddenly, if one considers that the assemblies lacking a side must be copied other, there remains the delta of the native DLL (arf, all would be so simple otherwise). ?I have therefore very used naivement my favorite tool "listdlls" (sysinternal) after to have created under Whidbey (LH) an application XAML classical (while using the wizard). ?Here the result on Longhorn:

Next, I copied stuck the complete catalog of the project under XP and (tried) to execute the Application1.exe. ?Well heard, that planted with an exception of non DLL found. ?Suddenly, to synchronize the all, here the manips that I carried out on XP:

Copy catalog C: \WINDOWS\Microsoft.NET\Windows of LH under XP (to the same place)

Merger of the catalog C: \WINDOWS\Microsoft.NET\Avalon XP and LH (wholesale, you copy all and in case of message overwrite you skippez)

Copy native files (here the key of the success) milcore.dll and WindowsCodecs.dll of LH on XP. ?This are the alone native files not having any are equivalent under XP. ?The others (ntdll, ole32, etc. ..) are (for the moment) rising compatible. ?This that wants to say that Avalon does not use (for the moment) no native function no existing on XP. ?I want to say by there, in a DLL known. ?In order not to to have to modify the files MSBuild "standard" (WindowsApplication.target being located under Microsoft. NET\Windows) I had to put in GAC the principal managed DLL used by Avalon: n : PresentationFramework.dll,WindowsBase.dll,WindowsUIAutomation.dll,PresentationCore. ?

Last very important thing. ?MsBuild possesses a custom Task that takes care of the generation of the code behind of the files Avalon. ?Suddenly, it is necessary for you also to put in GAC a very important DLL: PresentationBuildTasks.dll and to copy it in Microsoft. NET\Windows if this is not the case. ?Once you did all that, download the following zip, do you entertain to modify the file Windows.xaml and then done "MsBuild" to test the all. ?In less than 3 seconds, the ihm is reg?n?r?e and the execution is almost instantaneous. ?

I d?taillerais in another post the hack of Whidbey for be able to use all attending them Longhorn under Whidbey XP: -). ?A must. ?

from freetranslation, i hope i dont get a warning for posting that (><) but the link it refers to at th end is

http://www.dotnetguru.org/downloads/AvalonXP.zip

The sidebar is part of explorer.exe, I think the explorer.exe in Longhorn has massive linking to a zillion other Longhorn DLLs, meaning that even if you have Avalon you won't be able to have the genuine sidebar in Windows XP. However, I'm sure someone could write an Avalon-powered sidebar for Windows XP. :-)

What the hell is Avalon, what does it look like and what does it do?

1. Avalon is the graphics, display, and forms (windowing) engine for Longhorn. It is written in managed code and is meant to be used by other managed code. Avalon replaces GDI+ and Windows Forms technologies.

2. What Avalon does for the developer is makes it easier to make richer user interfaces. What it means for you is you'll find applications with richer, less bug-ridden user interfaces.

3. Avalon also provides a system called XAML. XAML is eXtensible Application Markup Language, and is an XML dialect for defining a user interface. You link the XAML file to a code-behind file, which is a VB.NET or C# file that defines the code that is activated when an event is triggered (e.g. clicking a button, selecting an item in a listbox, etc.).

4. Avalon doesn't really have a look. Build 4051 has an alternate look (view here) that appears in applications written in XAML, however this is most likely Avalon using a different DLL to render UI widgets which in turn has different graphics than the active theme (e.g. Slate).

visually ultragrid looks like crap. the amazon application presented at PDC would be a better example of avalon. i'd link a picture of it, but the site it was on is down. trying to find a mirror.

<edit>

well the next best thing i found to the amazon thing is a crappy video

    • Finally we can whole-heartedly recommend the AMD 9070 GRE thanks to this discount by Sayan Sen Earlier this month at Computex 2026 AMD released the Radeon RX 9070 GRE for a global audience. We reviewed the GPU and it scored 8 out of 10 for gaming and 7.5 out of 10 for productivity including things like AI performance. The card launched for $550 which we thought was a bit on the higher side, though currently you are getting the chance to get the Gigabyte Gaming variant of the GPU for just $500 thanks to this discount (purchase link under the specs table down below). As such we can finally whole-heartedly recommend this GPU. The card employs Gigabyte's WINDFORCE cooling system which combines multiple design elements such as alternate-spinning Hawk fans, a vapor chamber, and composite heat pipes to manage heat dissipation. The Server-grade Thermal conductive gel further helps in this department. The inclusion of a semi-passive cooling mode allows the fans to remain inactive under low workloads, which allows for reduced noise operation during lighter usage. There is dual BIOS switch that allows toggling between performance and silent modes. The technical specs of the Gigabyte Gaming RX 9070 GRE OC is given in the table below: Specification Value Boost Clock Up to 2920 MHz Game Clock Up to 2340 MHz Stream Processors 3072 Memory Clock 18 Gbps Memory Size 12 GB Memory Type GDDR6 Memory Bus 192-bit Memory Bandwidth 432 GB/s Card Bus Interface PCI Express 5.0 Max Resolution 7680 × 4320 Max Displays (Multi-view) 4 Card Dimensions 288 × 132 × 50 mm (L × W × H) Recommended Power Supply 700 W Power Connectors 2 × 8-pin Display Outputs 2 × DisplayPort 2.1a 2 × HDMI 2.1b Get it at the link below: GIGABYTE Gaming Radeon RX 9070 GRE 12GB GDDR6 GPU (GV-R907GREGAMING OC-12GD): $549.99 + $50 discount with promo code in mail => $499.99 (Sold and Shipped by Newegg US) This Newegg deal is US-specific and not available in other regions unless specified. This is a first-party seller link (at the time of article publishing); ensure that you also purchase from a first-party seller link only.
