the default xml namespace of the project must be msbuild 2003

Question

User2012297617 posted

I'm using Visual Studio 2017. I created a build definition to automate our build process.

For some reason, I'm getting this error: the default xml namespace of the project must be msbuild 2003. If the project is authored in the MSBuild 2003 format, please add xmlmsn = http://schema.microsoft.com/developer/msbuild/2003 to the <Project>.

Has anybody experience this error?  Is this an issue in .NET Core?

Hi lesponce,

As far as I think,this is an issue in .NET Core.Starting from VisualStudio 2015 MSBuild is provided as part of IDE (or build tools).

I suggest you could creat a MSbuild project,build properties and items.

Note:You must specify the xmlns namespace in the Project element. If ToolsVersion is present in a new project, it must be "15.0".

More details, you could refer to below article:

Yes, it seems like the issue is related to .NET Core.  I might go a different route.  Thanks for your feedback.
