How to specify ExcludeFromCodeCoverage at assembly level for dot net framework class library?

I want to exclude a test project from code coverage, I do see equivalent of same in .Net core 3.1 is adding below line of code in csproj file

<ItemGroup>
        <AssemblyAttribute Include="System.Diagnostics.CodeAnalysis.ExcludeFromCodeCoverage" />
</ItemGroup>

How to specify same thing in dot net framework 4.8 csproj class library file?

An alternative for this (I've only tested it in .NET 6) is to include an AssemblyInfo.cs file in your project that includes the following:

using System.Diagnostics.CodeAnalysis;

[assembly: ExcludeFromCodeCoverage]

UPDATE:

This works in at least .NET 6 and .NET Standard 2.1. It definitely doesn't work in .NET Standard 2.0 as the [ExcludeFromCodeCoverage] attribute cannot be used with the assembly: declaration in that version. I haven't tried it in any other versions.

The <AssemblyAttribute> item only works in SDK-based projects. So if you create an SDK-based .NET Framework csproj, it will work (do note this might clash with any existing AssemlyInfo.cs if one exists). e.g.:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net48</TargetFramework>
    <OutputType>Library</OutputType>
  </PropertyGroup>
  <ItemGroup>
    <AssemblyAttribute Include="System.Diagnostics.CodeAnalysis.ExcludeFromCodeCoverage" />
  </ItemGroup>
</Project>

Otherwise, I worked on a similar situation a while back and created a drop-in replacement for the assembly info generation logic for non-SDK csproj, see https://github.com/dasMulli/AssemblyInfoGenerationSdk for that (do log issues if it doesn't work). Do note that you may need to disable some generation of e.g. Version attributes similar to SDK-style projects so it doesn't clas with existing AssemblyInfo.cs files.
