Project rebuilds every time I open the designer

[Andrew-Lahikainen]

Severity

P3 - Medium (Minor functionality affected)

Describe the Bug with repro steps

Expected behaviour:

• If no changes have been made to the custom code project, the designer should not rebuild it when opening a new designer tab

Actual behaviour:

• Custom code project gets rebuilt every time. This means I have to wait approx. 20 seconds for every workflow I open.
• Sometimes the project cannot be built and deployed to the lib folder because some process holds a lock on it. I have to manually kill processes - this adds another 20 - 25 seconds because I have to rebuild again otherwise my function definitions will be broken in my workflow.

Notes:

• The issue with builds not completing due to processes not being killed after debugging was resolved at one point, and has now become an issue again
• I have migrated this .csproj file from a project that was initialized with an old version of the extension so there may be issues with how I copied over settings from a new project.
• There seems to be 4-5 places that settings are checked. It would be really nice to have 1 document where I can see which settings are set in which place. I'd like to know how these are used:
  • LogicApp/local.settings.json
  • LogicApp/workflow-designtime/*
  • LogicApp/.vscode/*
  • Functions/.vscode/* (assuming you call your custom code project "Functions")
  • Functions/Functions.csproj

This is my .csproj

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <IsPackable>false</IsPackable>
    <TargetFramework>net8</TargetFramework>
    <AzureFunctionsVersion>v4</AzureFunctionsVersion>
    <OutputType>Library</OutputType>
    <PlatformTarget>AnyCPU</PlatformTarget>
    <LogicAppFolderToPublish>$(MSBuildProjectDirectory)\..\LogicApp</LogicAppFolderToPublish>
    <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    <SelfContained>false</SelfContained>
    <CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies>
    <Nullable>enable</Nullable>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.Abstractions" Version="1.3.0" />
    <PackageReference Include="Microsoft.Azure.Functions.Worker.Sdk" Version="1.15.1" />
    <PackageReference Include="Microsoft.Azure.Workflows.Webjobs.Sdk" Version="1.2.0" />
    <PackageReference Include="Microsoft.Extensions.Logging.Abstractions" Version="6.0.0" />
    <PackageReference Include="Microsoft.Extensions.Logging" Version="6.0.0" />
  </ItemGroup>
  <ItemGroup>
    <ProjectReference Include="../../Shared/Shared.csproj" />
    <ProjectReference Include="../../../../Core/Core.csproj" />
  </ItemGroup>
  <Target Name="TriggerPublishOnBuild" AfterTargets="Build">
    <CallTarget Targets="Publish" />
  </Target>
</Project>

I have also tried <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory> but I think the issue is that it attempts to build when it doesn't need to.
