测试文件夹不断在.NET 6中的同一目录中创建

Question

我有一个.NET 6 Web API Project MAIN，在其中我有一个名为tests的文件夹，我保留所有测试，解决方案看起来像这样：
main.sln：

Microsoft Visual Studio Solution File, Format Version 12.00
# Visual Studio Version 16
VisualStudioVersion = 16.0.30114.105
MinimumVisualStudioVersion = 10.0.40219.1
Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "main", "main.csproj", "{218486FE-31A5-45A1-A6EC-3AD4D3ED9E6D}"
EndProject
Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "Tests", "Tests\Tests.csproj", "{08294007-70CB-4095-847B-1219FA1E7DBA}"
EndProject
Global
    GlobalSection(SolutionConfigurationPlatforms) = preSolution
        Debug|Any CPU = Debug|Any CPU
        Release|Any CPU = Release|Any CPU
    EndGlobalSection
    GlobalSection(SolutionProperties) = preSolution
        HideSolutionNode = FALSE
    EndGlobalSection
    GlobalSection(ProjectConfigurationPlatforms) = postSolution
        {218486FE-31A5-45A1-A6EC-3AD4D3ED9E6D}.Debug|Any CPU.ActiveCfg = Debug|Any CPU
        {218486FE-31A5-45A1-A6EC-3AD4D3ED9E6D}.Debug|Any CPU.Build.0 = Debug|Any CPU
        {218486FE-31A5-45A1-A6EC-3AD4D3ED9E6D}.Release|Any CPU.ActiveCfg = Release|Any CPU
        {218486FE-31A5-45A1-A6EC-3AD4D3ED9E6D}.Release|Any CPU.Build.0 = Release|Any CPU
        {08294007-70CB-4095-847B-1219FA1E7DBA}.Debug|Any CPU.ActiveCfg = Debug|Any CPU
        {08294007-70CB-4095-847B-1219FA1E7DBA}.Debug|Any CPU.Build.0 = Debug|Any CPU
        {08294007-70CB-4095-847B-1219FA1E7DBA}.Release|Any CPU.ActiveCfg = Release|Any CPU
        {08294007-70CB-4095-847B-1219FA1E7DBA}.Release|Any CPU.Build.0 = Release|Any CPU
    EndGlobalSection
EndGlobal

main.csproj：

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

  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>

    <PackageReference Include="System.IdentityModel.Tokens.Jwt" Version="6.17.0" />

  </ItemGroup>

</Project>

和tests.csproj

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

    <Nullable>enable</Nullable>

    <IsPackable>false</IsPackable>

    </PackageReference>
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\main.csproj" />
  </ItemGroup>

</Project>

每次我运行测试，文件夹bin和obj fromTests 正在反复创建类似的情况：

~/main/bin/Debug/net6.0/Tests/bin/Debug/net6.0/Tests/bin/Debug/net6.0/Tests/bin/Debug/net6.0/Tests

我的解决方案或CSPROJ文件我做错了什么？还是可以这样创建可以？
