possible dup of #1384
@eren-dhoheiri can you change the title to "A file matching the name ApiControllerWithContext.cshtml" ?

I just installed dotnet 5 in my ubuntu 20.04, was following the rest api tutorial and this problem still exists.

[marcovelarde]

Same problem here using dotnet 5.

[Hackjaku]

Same using dotnet 5 on Linux

[Rick-Anderson]

Try the following:

dotnet tool  uninstall  -g dotnet-aspnet-codegenerator
dotnet tool install -g dotnet-aspnet-codegenerator

[lampsbr]

@Rick-Anderson I tried but it still didn't work:

$ dotnet tool uninstall -g dotnet-aspnet-codegenerator Tool 'dotnet-aspnet-codegenerator' (version '5.0.0') was successfully uninstalled. $ dotnet tool install -g dotnet-aspnet-codegenerator You can invoke the tool using the following command: dotnet-aspnet-codegenerator Tool 'dotnet-aspnet-codegenerator' (version '5.0.0') was successfully installed. $ dotnet aspnet-codegenerator controller -name TodoItemsController -async -api -m TodoItem -dc TodoContext -outDir Controllers Building project ...

@lampsbr we've got thousands of customers reporting success. Most likely, you're missing a step or something is wrong with your computer. If you're confident you haven't missed a step, you could try the following:

• Update your computer (mostly so it doesn't do a reboot before you complete)
• Install VS on Windows Sandbox.
• Try in the sandbox.

There is a templates folder in /home/yourusername/.nuget/packages/microsoft.visualstudio.web.codegenerators.mvc/5.0.1/, which contains many templates needed, but in ubuntu, Vscode can't use it correctly. So you can copy whole Templates folder in your project folder(without two identity template subfolders).
