Converting ASP.NET MVC Framework csproj Question

Question

Hello - I have a few different ASP.NET MVC projects that build on .NET Framework 4.8 I want to convert to the new SDK style csproj format. I was able to convert it over fine, but once I try and publish the project, all of the DLL files are not located in a /bin folder and nothing works. Instead they are just all dumped in one big folder with the other web assets (CSS, JS, etc) are at the same level. I want to know if there is some setting that can be applied to the SDK csproj file that indicates it needs to be deployed as the old MVC projects were?

Thanks

When migrating ASP.NET MVC projects from .NET Framework 4.8 to the new SDK-style .csproj format, publishing might result in all files (DLLs, CSS, JS, etc.) being placed at the same level. To address this and mimic the old deployment structure, you can configure a few settings in the .csproj file.1. Publish Output Structure: You can ensure that your assemblies and web assets are placed in their appropriate folders by adding the following settings to your .csproj:

<PropertyGroup>
  <!-- Ensure DLLs go into a bin folder -->
  <PublishDir>$(PublishDir)\bin\</PublishDir>
  <!-- Ensure web assets (like CSS, JS) go into the wwwroot folder -->
  <WebPublishMethod>FileSystem</WebPublishMethod>
  <TargetFramework>net6.0</TargetFramework> <!-- Adjust as per your target version -->
</PropertyGroup>

<ItemGroup>
  <None Update="wwwroot\**\*;web.config">
    <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
  </None>
</ItemGroup>

1. Organizing the Output: You can also use the CopyToOutputDirectory property to ensure resources are copied to the right locations.

For example, you can add the following lines to ensure certain assets are copied correctly:

<ItemGroup>
  <Content Include="wwwroot\**\*;Views\**\*;web.config">
    <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
  </Content>
</ItemGroup>

Self-contained or Framework-dependent: Depending on whether you're publishing the app as self-contained or framework-dependent, ensure the output directory is correctly structured:

<PropertyGroup>
  <RuntimeIdentifier>win-x64</RuntimeIdentifier> <!-- or use linux-x64, osx-x64, etc. -->
  <SelfContained>false</SelfContained> <!-- If not self-contained -->
</PropertyGroup>

By organizing these properties, your output structure will better resemble the traditional bin and web folder setup in older ASP.NET MVC projects. Let me know if you need more details!
