Jet brains Rider compile error with unreal engine while building, xml namespace
> 0>UnrealBuildTool.csproj(1,1): Error MSB4041 : 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 <Project> element. If the project has been authored in the old 1.0 or 1.2 format, please convert it to MSBuild 2003 format.
I have tried everything i looked everywhere on google nothing helped i installed 3.1 net core
