Hi Roger,
I have only recompiled v2.4.8 GSP source code don't edit any code file by Visual Studio 10, then I copied GalleryServerPro.Web.dll to bin folder in my IIS server, but it error with some, example: can't play with media (mp3..) that will play by silverlight (it don't display silverlight's interface, only title of media...). but when I download GalleryServerPro.Web.dll from your site it wouldn't error!
Note: when rebuild solution, I tested by two methods, the firt is choose dotnet framework for website solution is version 2.0 and second is version 3.5. but both of them have error.
My background are: IIS, DotNet Frame work v3.5 installed.
thanks
