.NET Core Build is failing

[Ciwan]

Hello

I am new a total n00b to DevOps, but I have heard that BitBucket's pipline feature makes things super easy, so I thought I would try it.

I have created the bitbucket-pipelines.yml file at the root my repository.

But I am getting an error when my pipline runs. The yml file has this:

```
# This is a sample build configuration for .NET Core.
# Check our guides at https://confluence.atlassian.com/x/5Q4SMw for more examples.
# Only use spaces to indent your .yml configuration.
# -----
# You can specify a custom docker image from Docker Hub as your build environment.
image: microsoft/dotnet:sdk

pipelines:
  default:
    - step:
        caches:
          - dotnetcore
        script: # Modify the comma`nds below to build your repository.
          - export PROJECT_NAME=Phoneden
          - dotnet restore
          - dotnet build $PROJECT_NAME
```

The message I get when the pipeline fails is:

MSBUILD : error MSB1009: Project file does not exist.
Switch: Phoneden

I assume by Project file, it is talking about the solution file, and you can see from my screenshot that it does exist!

I'm confused. Any help would be greatly appreciated.

Thank you.

+1 I have the same question, seems like point to a sln file has no effect? I managed to make it build by pointing directly to my core csproj like dotnet build ./src/MyCoreApp/MyCoreApp.csproj

I guess this is up to the SDK on the image installed, buuuut its the latest 2.1.402 (at the moment of writing) so not so sure after all. You can check that out with dotnet --info in the pipeline script step

I got it to work by adding the `.sln` extension.
