PMC Tools fail when directory contains "["

[yangbocheng]

I want your help
I have created a totally new Net Core SDK 2.2.0 web program.(named "web2_2new")
Just edit this .csproj, and then test Add-Migration. Then it tells:

PM> add-migration vc1
Unable to resolve startup project ''.
Using project 'web2_2new' as the startup project.
Your startup project 'web2_2new' doesn't reference Microsoft.EntityFrameworkCore.Design. This package is required for the Entity Framework Core Tools to work. Ensure your startup project is correct, install the package, and try again.

proj:

netcoreapp2.2 InProcess

proj:

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

  <PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.App" />
    <PackageReference Include="Microsoft.AspNetCore.Razor.Design" Version="2.2.0" PrivateAssets="All" />
  </ItemGroup>

    <PackageReference Include="Pomelo.EntityFrameworkCore.MySql" Version="2.2.0" />
  </ItemGroup>

</Project>

@yangbocheng Can you post the project/solution here?

[yangbocheng]

@ajcvickers

I hava found the reason, maybe it's a problem about path.

If the name of folder contains "[" or "[any]", Use "Add-migration", it will produce the error

Those wrong path like:
"D:\2017\ASP.NET Core[1\web1\yoursolution"    --->other error
"D:\2017\ASP.NET Core[1]\web1\yoursolution"     --->doesn't reference Microsoft.EntityFrameworkCore.Design

Containing folder name ConsoleApp[6]

[smitpatel]

renaming folders/solution/csproj file to remove brackets make it work.

[bricelam]

-Verbose?

[smitpatel]

Will try with that. There were also few mistakes on my part. Probably need to run restore again after renames?
First error I am focusing on is why the startup project was not resolved.

[bricelam]

I'm also happy to take over the investigation too, if you want. I was going to tackle this one alongside the network path issues.

[smitpatel]

I saw poachable label so I was looking if this is something I can even understand. Up to you, feel free to un-assign me if you want to take over. I can dig in with my little knowledge and some guidance. 😨

[bricelam]

I'll take it and free you up to add more value elsewhere. 😉
