Latest Version returns error: "Scaffolding failed. Failed to get Project Context" #1388

Open JacquiM opened 4 years ago

JacquiM commented 4 years ago

Steps to reproduce:

Once the ASP.NET MVC Core Web App has been created, run the following commands using the dotnet CLI: dotnet tool install -g dotnet-aspnet-codegenerator dotnet add package Microsoft.VisualStudio.Web.CodeGeneration.Design dotnet build dotnet aspnet-codegenerator controller -name MoviesController -actions -api

Expected behavior:

This should create an API Controller with methods in it.

Actual behavior:

Scaffolding failed. Failed to get Project Context

Even when referencing options that do not exist, the error persists as "Failed to get Project Context". When uninstalling codegenerator and reinstalling version 3.1.3, the controller is created.

Additional information about the project being scaffolded, such as:

Target framework(s):

.NET Core 3.1

Package version of Microsoft.VisualStudio.Web.CodeGeneration.Design - this may be added to your project by scaffolding:

3.1.4

deepchoudhery commented 4 years ago

Hmm I cannot reproduce the debug. I'm assuming the build produced no errors. That is the only time that error message should be thrown. Would you mind opening the project in VS(if you have it installed) and building it?

Wondering what dotnet sdk you are on? You can check using dotnet --info.

Some people have suggested downgrading the dotnet-aspnet-codegenerator to 3.1.3, even that did not help. I have tried using 3.1.0 too.

zach-delong commented 3 years ago

I also have this same issue. I have been following this tutorial but I have run up against this same error, and downgrading to scaffolder 3.1.3 fixed my error on MacOS.

Dotnet version: 3.1.201

bioan commented 3 years ago

Have this issue as well. I suspect this might be an issue on Linux/MacOS, because the project itself builds and runs just fine. Testing it on Windows/VS everything is fine as well.

sorin-costea commented 3 years ago

Same problem here (Windows 10), downgrading to 3.1.3 solved it.

ccaneke commented 3 years ago

Linux, still happened on 3.1.3 until I built the project first.

RenegadeMaster commented 3 years ago

I had this issue and I managed to get it to work. The project woudl build but it complained about missing references as warnings. I had deleted some projects that were still references in files. This did not stop it from building successfully though, it just created warnings. After removing these references (in the .csproj files) and building without missing reference warnings, I was able to scaffold.

Note however that it still requires a downgrade to 3.1.0

qin-guan commented 3 years ago

i'm experiencing the issue but it seems to be resolved when i run dotnet build before scaffolding

klauszou commented 3 years ago

Just build your project first before scaffolding, if it can build then the scaffolding should be fine, otherwise this will continue appear.

psmatsinhe commented 3 years ago

Hi, Could you run a $dotnet restore and dotnet build on the project successively. That exception should only pop up when a build/restore fails.

Doing this fixed the issue for me

i have the same problem after i updated to 3.1.10 the error was gone.

EtienneBel commented 2 years ago

Had the same problem when run

dotnet aspnet-codegenerator controller -name TodoItemsController -async -api -m TodoItem -dc TodoContext -outDir Controllers.

i solve this by unsinstalling dotnet aspnet-codegenerator controller

dotnet tool uninstall -g dotnet-aspnet-codegenerator

and install a stable version with my sdk version (check it with dotnet --info)

dotnet tool install -g dotnet-aspnet-codegenerator --version 6

and it's work for me

I have the dotnet 5.0.1 and 6.0.1 installed on my pc, and downgrading dotnet-aspnet-codegenerator to 3.1.3 didn't work.

@EtienneBel's suggestion fixed the issue.

Microsoft should update the doc to use the stable version not 6.0.0-preview.7.21413.1. https://docs.microsoft.com/en-us/aspnet/core/tutorials/first-web-api?view=aspnetcore-6.0&tabs=visual-studio-code

Didn't work for me, my project structure is based on clean architecture, src folder containing Domain (where my entities are), Infrastructure (where my dbcontext and entity configurations are) and (ASP .NET Core SPA template) WebUI (where I'm trying to generate my api controllers)
