Visual Studio 2017 version 15.3 and, in some cases, Visual Studio for Mac offer a number of significant enhancements for .NET Core developers.
If the .NET Core 2.0 SDK is installed, you can retarget .NET Core 1.x projects to .NET Core 2.0 and .NET Standard 1.x libraries to .NET Standard 2.0.
To retarget your Visual Studio project, you open the Application tab of the project's properties dialog and change the Target framework value to .NET Core 2.0 or .NET Standard 2.0.
You can also change it by right-clicking on the project and selecting the Edit *.csproj file option.
<Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <OutputType>Exe</OutputType> <TargetFramework>netcoreapp2.0</TargetFramework> </PropertyGroup> </Project>
Whenever you modify your code, Live Unit Testing automatically runs any affected unit tests in the background and displays the results and code coverage live in the Visual Studio environment.
If you are building a project for multiple target frameworks, you can now select the target platform from the top-level menu.
The following project targets 64-bit macOS X 10.11 (osx.10.11-x64) and 64-bit Windows 10/Windows Server 2016 (win10-x64).
You can select the target framework before selecting the project button, in this case, to run a debug build.
You can now install the .NET Core SDK independently of Visual Studio.
