No executables found matching command 'dotnet-aspnet-codegenerator'"

Question

When trying to add a Controller in an ASP.NET Core project using Visual Studio 15 Enterprise with Update 3, I get the error below:

\"The was an error running

Answer 1

Just add tag 'DotNetCliToolReference ' and package code design on .csproj and execute code-generate command on root solution. Thats worked to me.

.csproj <ItemGroup> <DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.3" /> </ItemGroup>

<ItemGroup> ... <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="2.0.3" /> </ItemGroup>

Command PS C:\Users\miche\projetos\asp_net_core\crud> dotnet aspnet-codegenerator controller -name ProdutosController -m Produto -dc AppDataContext --relativeFolderPath Controllers --useDefaultLayout --referenceScriptLibraries

Don't forget to build and restore solution after add package ;)

For VS 2015, in project.json file -

under dependencies add -

"Microsoft.VisualStudio.Web.CodeGeneration.Tools": {
  "version": "1.0.0-preview2-final",
  "imports": [
    "portable-net45+win8"
  ]
},
"Microsoft.VisualStudio.Web.CodeGenerators.Mvc": "1.0.0-preview2-final"

then under tools add-

"Microsoft.VisualStudio.Web.CodeGeneration.Tools": {
  "version": "1.0.0-preview2-final",
  "imports": [
    "portable-net45+win8"
  ]
}

I encountered the same issue in Visual Studio Mac Community Edition 2017. Prior to running the scaffold command from the project directory, make sure the directory has the Program.cs, Startup.cs and .csproj files. if not, then run the command ls-al and then cd into the project directory which would be inside your current project directory and then execute the scaffold command. An obvious mistake many overlook.

For the latest version, in project.json add the following under dependencies:

"Microsoft.VisualStudio.Web.CodeGeneration.Tools": {
  "version": "1.1.0-preview4-final",
  "type": "build"
},
"Microsoft.VisualStudio.Web.CodeGenerators.Mvc": {
  "type": "build",
  "version": "1.1.0-preview4-final"
}

and the following under tools:

"Microsoft.VisualStudio.Web.CodeGeneration.Tools": {
  "version": "1.1.0-preview4-final",
  "imports": [
    "portable-net45+win8"
  ]
}

In Visual Studio Code change your yourproject.csproj

<pre>
<ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.App" />
    <PackageReference Include="Microsoft.AspNetCore.Razor.Design" Version="2.1.2" PrivateAssets="All" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Sqlite" Version="2.1.4" />
    <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="2.1.6" PrivateAssets="All" />
    <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.4" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" version= "2.1.0-preview1-final" />
    <PackageReference Include="Microsoft.Extensions.SecretManager.Tools" version= "2.0.2" />
    <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.4" />
  </ItemGroup>
  <ItemGroup>
  <DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.2" />
  <DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" version="2.1.0-preview1-final" />
  </ItemGroup>`enter code here`
</pre>

If you're using csproj (Visual Studio 2017) instead of project.json, then you need to add the following to your csproj file:

    <ItemGroup>
        <DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="1.0.1" />
    </ItemGroup>
