I am trying to add an existing project to my source project in VS2015, and I am getting the following error:
Visual Studio 2015 - The default XML namespace of the project must be the MSBuild XML namespace. If the project is authored in the MSBuild 2003 format, please add xmlns="http://schemas.microsoft.com/developer/msbuild/2003" to the element. if the project has been authored in the old 1.0 or 1.2 format, please convert it to MSBuild 2003 fromat.
How can I solve this?
<TargetFrameworks>netcoreapp2.0;net461</TargetFrameworks>
in your project file, the target framework should not show anything. – Leo Liu-MSFT
