Today, we released a new Windows 10 Preview Build of the SDK and the Mobile Emulator to be used in conjunction with Link Removed (Build 16257 or greater). The Preview SDK Build 16257 contains bug fixes and under development changes to the API surface area.
The Preview SDK and Mobile Emulator can be downloaded from Link Removed.
For feedback and updates to the known issues, please see the developer forum. For new feature requests, head over to our Link Removed
Things to note:
Crogram files (x86)Windows Kits10bin10.0.16232.0x86genxbf.dll:Crogram files (x860Windows Kits10bin10.0.16232.0x86genxbf.dll(0,0): Error WMC0621: Cannot resolve ‘GenXbf.dll’ under path ‘Crogram files (x860Windows Kits10bin10.0.16232.0x86genxbf.dll’. Please install the latest version of the Windows 10 Software Development Kit.
Process ‘msbuild.exe’ exited with code ‘1’.
This will occur if the minimum target platform version is set to 10.0.16225.0. To work around this, right click on your project file and choose properties or open your project file in your favorite editor, and change the version to a previous released SDK. For example:
<WindowsTargetPlatformVersion>10.0.15063.0</WindowsTargetPlatformVersion>
midlrt : command line error MIDL1012: [msg]argument illegal for switch / [context]ns_prefix
midlrt : command line error MIDL1000: [msg]missing source-file name
To work around this temporarily you will need to use the previous version of the MidlRT.exe tool. You can do this by changing your changing your Target Platform Version to a currently installed previous SDK.
<WindowsTargetPlatformVersion>10.0.15063</WindowsTargetPlatofrmVersion>
Breaking Changes
ecmangen.exe removal from the SDK: ecmangen.exe will no longer ship with the Windows SDK. Developers who rely on ecmangen for event manifest creation are advised to install the Windows Creator Edition of the SDK to obtain the file. Developers may also use notepad or other XML editor of choice for manifest creation. A schema file is available on MSDN to aid in manifest creation, for tools that support it.
API Updates and Additions
When targeting new APIs, consider writing your app to be adaptive in order to run correctly on the widest number of Windows 10 devices. Please see Link Removed for more information.
The following are the API changes since the 16232 Preview SDK, please reference that list. The TreeView control has been removed, but will be back soon in the next release of Windows and the Preview SDK.
Addition from Preview SDK 16232
namespace Windows.Storage {
public sealed class AppDataPaths
public sealed class SystemDataPaths
public sealed class UserDataPaths
}
Removals from Preview SDK 16232
namespace Windows.UI.Xaml.Automation.Peers {
public class TreeViewItemAutomationPeer : ListViewItemAutomationPeer
public class TreeViewListAutomationPeer : SelectorAutomationPeer
}
namespace Windows.UI.Xaml.Controls {
public class TreeView : Control
public sealed class TreeViewExpandingEventArgs
public class TreeViewItem : ListViewItem
public sealed class TreeViewItemClickEventArgs
public class TreeViewList : ListView
public class TreeViewNode : DependencyObject, IBindableIterable, IBindableObservableVector, IBindableVector
public enum TreeViewSelectionMode
public sealed class XamlBooleanToVisibilityConverter : IValueConverter
public sealed class XamlIntegerToIndentationConverter : IValueConverter
}

Things to note:
- This build works in conjunction with previously released SDKs and Visual Studio 2017. You can install this SDK and still also continue to submit your apps that target Windows 10 Creators build or earlier to the store.
- The Windows SDK will now formally only be supported by Visual Studio 2017 and greater. You can download the Visual Studio 2017 here.
- Designer fails to render: When viewing the XAML in the Designer Window in Visual Studio, the controls fail to render. This can be resolved by using Visual Studio 2017.3 Preview.
- Compilation fails on non-Windows 10 platforms (need to see if fixed)
When building apps on previous platforms, you may get a build error:
Crogram files (x86)Windows Kits10bin10.0.16232.0x86genxbf.dll:Crogram files (x860Windows Kits10bin10.0.16232.0x86genxbf.dll(0,0): Error WMC0621: Cannot resolve ‘GenXbf.dll’ under path ‘Crogram files (x860Windows Kits10bin10.0.16232.0x86genxbf.dll’.

- WRL projects fail to compile with MIDLRT error: When building my WRL project that contains a WinRT Component, the project no longer compiles. I get the following errors:
midlrt : command line error MIDL1012: [msg]argument illegal for switch / [context]ns_prefix
midlrt : command line error MIDL1000: [msg]missing source-file name
