- add LTS versions - Dotnet Core 2.1 fails due to issue with linprocfs (PR pending) .NET Core is a free and open-source managed software framework. It consists of CoreCLR, a complete runtime implementation of CLR, the virtual machine that manages the execution of .NET programs. CoreCLR comes with an improved just-in-time compiler, called RyuJIT. .NET Core also includes CoreFX, which is a partial fork of FCL. While .NET Core shares a subset of .NET Framework APIs, it comes with its own API that is not part of .NET Framework. Further, .NET Core contains CoreRT, the .NET Native runtime optimized to be integrated into AOT compiled native binaries. A variant of the .NET Core library is used for UWP. .NET Core's command-line interface offers an execution entry point for operating systems and provides developer services like compilation and package management. .NET Core supports four cross-platform scenarios: ASP.NET Core web apps, command-line apps, libraries, and Universal Windows Platform apps. It does not implement Windows Forms or WPF which render the standard GUI for desktop software on Windows. .NET Core is also modular, meaning that instead of assemblies, developers work with NuGet packages. Unlike .NET Framework, which is serviced using Windows Update, .NET Core relies on its package manager to receive updates. Differential Revision: https://reviews.freebsd.org/D13870

Telemetry
|
|
---------
|
|
The .NET Core tools collect usage data in order to improve your experience.
|
|
The data is anonymous and does not include command-line arguments. The data is
|
|
collected by Microsoft and shared with the community. You can opt out of
|
|
telemetry by setting a DOTNET_CLI_TELEMETRY_OPTOUT environment variable to 1
|
|
using your favorite shell. You can read more about .NET Core tools telemetry @

CA Root Certificates for NSS
|
|
----------------------------
|
|
.NET Core requires NSS CA certificates installed. The recommended way to
|
|
install the certificates is to:
|
|
|
|
# pkg install ca_root_nss
|
|
# ln -s /usr/local/share/certs/ca-root-nss.crt \
|
|
/compat/linux/etc/pki/tls/certs/ca-bundle.crt
|
|
|
|
Failed to initialize CoreCLR, HRESULT: 0x8007001F
|
|
-------------------------------------------------
|
|
.NET core may produce the above error message if the system has exceeded
|
|
capacity for wired memory, or is unprivilaged allocations of wired memory is
|
|
not permitted.
|
|
|
|
To ensure unprivilaged allocation of wired memory is allowed, as root:
|
|
|
|
# sysctl security.bsd.unprivilaged_mlock=1
|
|
|
|
To preserve this setting across reboots, append the following to
|
|
/etc/sysctl.conf:
|
|
|
|
security.bsd.unprivilaged_mlock=1
|
|
|
|
To check the usage and limit of wired memory see the 'vm.stats.vm.v_wire_count'
|
|
and 'vm.max_wired' sysctl(8) respectively. To increase the wired memory
|
|
capacity set 'vm.max_wired' to a value greater than 'vm.stats.vm.v_wire_count'.
|
|
.NET Core only requires ~128k wired memory per running application.
|
|
|
|
For example, if one has:
|
|
|
|
# sysctl vm.stats.vm.v_wire_count
|
|
vm.stats.vm.v_wire_count: 1332146
|
|
# sysctl vm.max_wired
|
|
vm.max_wired: 1331964
|
|
|
|
then increasing 'vm.max_wired' will enable .NET Core to run:
|
|
|
|
# sysctl vm.max_wired=1333000
|
