You can download this update either from Microsoft Download Center or directly from Visual Studio 2015 by following this path: "Tools -> Extensions and Updates -> Updates -> Product Updates".


This patch includes fixes for the following issues:

    1. An ICE when you allocate an array of a __declspec(dllimport) class type with a default constructor with default arguments has been resolved.
    2. When targeting .NET Framework 4.6, ASP.NET Core or UWP 10.0, the Portable Class Library tooling that is used to generate a project.json that used the "dotnet" TFM. The "dotnet" TFM has been obsoleted and may no longer be supported by NuGet packages. To avoid this issue in the future, the PCL tooling has been changed to always target .NET Standard, when selecting specific target platforms.
    3. Potential mis-compilation of code calling functions similar to std::min/std::max on floating point values.
    4. You may experience Visual Studio crashes when you debug applications from Visual Studio on the Anniversary Update of Windows. To workaround the issue, update Visual Studio with the Anniversary Update of Windows SDK and tools. If that is not possible for you, go to “Options –> Debugging –> General –> Enable UI Debugging Tools for XAML” and uncheck the checkbox.
    5. Improved debugging reliability when debugging Visual C++ or CLI code.
    6. When you debug JavaScript eval code, if there are eval codes with source map following eval code without source map, debugger crashes when stepping into eval code without source map.
    7. After you revert MFC binary compatibility issues for runtime DLLs in Visual Studio 2015 Update 3, KB3165756 failed to include MFC static libraries matching the reverted code. This update includes MFC static libraries that were missed in that previous update.
    8. Fixed implicit (group based) permission handling when you use an AAD account during packaging.
    9. Authored the resource dll. Now customer can load the Test Explorer Window with localized strings.
