Asp.net Core: Duplicate 'global::System.Runtime.Versioning.TargetFrameworkAttribute' atribute
I have a project web, be developing with Asp.net Core 3.1.
Everything work well but one day I got the latest code from Git and builds I got an error Duplicate 'global::System.Runtime.Versioning.TargetFrameworkAttribute' attribute.
Error CS0579 Duplicate 'global::System.Runtime.Versioning.TargetFrameworkAttribute' attribute
D:\GameOBJ\obj\Debug\netcoreapp3.1\.NETCoreApp,Version=v3.1.AssemblyAttributes.cs
The following code is autogenerated in the obj/Debug/netcoreapp3.1 folder
// using System; using System.Reflection;
[assembly: global::System.Runtime.Versioning.TargetFrameworkAttribute(".NETCoreApp,Version=v3.1", FrameworkDisplayName = "")]
I checked all project versions but nothing change. I also tried to clear and rebuild all solutions but it still not work for me.

I got the same error in VS2019, to resolve this issue you can open
.csproj
and add line code below inside tag<PropertyGroup>
:<GenerateTargetFrameworkAttribute>false</GenerateTargetFrameworkAttribute>
And then save this file, clear and rebuild project.
I hope it helpful for you.

Add the following two lines to the
<PropertyGroup>
.<PropertyGroup> <GenerateAssemblyInfo>false</GenerateAssemblyInfo> <GenerateTargetFrameworkAttribute>false</GenerateTargetFrameworkAttribute> </PropertyGroup>
I try it and fixed it for me.
