How to enforce .Net Core project always take the file Build Action according to the file extension

Question

The issue: If I change the file extension from the visual studio, the file Build Action will be according to the previous Build Action and not according to the new file extension.

There is a way to enforce the visual studio always takes the Build Action from the file extension?

Example:

1. Create a new .Net Core 3.1 Class library. There is a single file (Class1.cs) The csproj will be like this:

   <Project Sdk="Microsoft.NET.Sdk">
   
     <PropertyGroup>
       <TargetFramework>netcoreapp3.1</TargetFramework>
     </PropertyGroup>
   
   </Project>
   

2. Change the name of Class1.cs to Class1.txt from the visual studio. The result, Class1.txt is with Build Action Compile although it is a text file. The content of csproj:

<Project Sdk="Microsoft.NET.Sdk">

      <PropertyGroup>
        <TargetFramework>netcoreapp3.1</TargetFramework>
      </PropertyGroup>

      <ItemGroup>
        <None Remove="Class1.txt" />
      </ItemGroup>

      <ItemGroup>
        <Compile Include="Class1.txt" />
      </ItemGroup>

    </Project>

Additional information:

1. I'm using Visual Studio 2019.
2. If I change the file extension from the file system the issue doesn't appear.

Update:

A possible solution is to change the file Build Action after each file rename, but I want an automatic way.
