A first hand look from the .NET engineering teams
We are happy to announce the availability of the .NET Framework 4.5.2. It is a highly compatible, in-place update to the .NET Framework 4, 4.5 and 4.5.1. You can download the releases now,
We incorporated feedback we received for the .NET Framework 4.5.1 from different feedback sources to provide a faster release cadence. In this blog post we will talk about some of the new features we are delivering in the .NET Framework 4.5.2.
High DPI Improvements is an opt-in feature to enable resizing according to the system DPI settings for several glyphs or icons for the following Windows Forms controls: DataGridView, ComboBox,ToolStripComboBox, ToolStripMenuItem and Cursor. Here are examples of before and after views once this change is opted into.
The red error glyph barely shows up and will eventually disappear with high scaling
The red error glyph scales correctly.
The ToolStripMenu drop down arrow is barely visible, eventually won’t be usable with high scaling
The drop down arrow in the ToolStripMenu scales correctly
Distributed transactions enhancement enables promotion of local transactions to Microsoft Distributed Transaction Coordinator (MSDTC) transactions without the use of another application domain or unmanaged code. This has a significant positive impact on the performance of distributed transactions.
More robust profiling with new profiling APIs that require dependent assemblies that are injected by the profiler to be loadable immediately, instead of being loaded after the app is fully initialized. This change does not affect users of the existing ICorProfiler APIs. Before this feature, diagnostics tools that do IL instrumentation via profiling API could cause unhandled exceptions to be thrown, unexpectedly terminating the process.
Improved activity tracing support in runtime and framework - The .NET Framework 4.5.2 enables out-of-process, Event Tracing for Windows (ETW)-based activity tracing for a larger surface area. This enables Application Performance Management vendors to provide lightweight tools that accurately track the costs of individual requests and activities that cross threads. These events are raised only when ETW controllers enable them.
For more information on usage of these features please refer to “What’s New in the .NET Framework 4.5.2”. Besides these features, there are many reliability and performance improvements across different areas of the .NET Framework.
Here are additional installers - pick package(s) most suitable for your needs based on your deployment scenario:
Please install the .NET Framework 4.5.2 and let us know your feedback via UserVoice, Visual Studio Connect or as comment to this blog post. We’re also listening on Twitter and Facebook.

Excellent , useful post. And it is easy to understand.
Any idea when v4.5.2 will be available via the Windows Update service? Right now 4.5.1 is still the "Important" update listed in the Windows Updates window.
When will be .NET Framework 4.5.2 available on WSUS?
(like the previous version blogs.msdn.com/.../the-net-framework-4-5-1-is-now-available-on-windows-update-and-wsus.aspx)
Net framework 4.5.2 produces too much flicker probably due to fps issue, it strains my eyes so I had to relax for a while during every hour of work or play. Can you fix it?
How can we determine which security patches for .NET Framework 4.x have been included in .NET Framework 4.5.2? We assume all previous patches for 4.x are included in 4.5.2 (as of RTM date), but we cannot seem to find that statement or list of patches anywhere.
In which SDK (I tried Aug 2014) will I find the updated corprof.h and corprof.idl that detail the updated interfaces and their methods?
Installing .Net 4.5.2 breaks mechanism for disabling WPF real-time stylus support:
Soon after installing 4.5.2 thru Windows Update I had DNS, IPv4, intermittent connectivity problems. More time "no internet connection" than connected. After uninstalling we're back to normal. What's the issue?
An update. Thought 4.5.2 was an issue an uninstalled it. Internet connectivity was fine for 2-4 hours and then it started cutting out again.
