.NET Framework March 2020 Update for Windows 10 1607 (Anniversary Update) and Windows Server 2016.

Tara Overfield

Today, we are releasing an update for .NET Framework 4.8 on Windows 10 1607 (Anniversary Update) and Windows Server 2016.

Security

This update does not contain any new security fixes. See January 2020 Security and Quality Rollup for the latest security updates.

Quality and Reliability

This release contains the following quality and reliability improvement.

CLR1

  • Addresses an issue when the hosting of a .NET Framework implemented COM server in a DllSurrogate (e.g. dllhost.exe) that is running elevated is unable to opt-out of a security mechanism put in place in .NET Framework 4.8. This fix respects the opt-out mechanism and permits the COM server the ability to properly activate. This update does nothing to change the behavior or robustness of .NET Framework 4.8 when the opt-out mechanism is not set.

1 Common Language Runtime (CLR)
