No project file(csproj) found in the directory.

Error message

No project file(csproj) found in the directory.

What it means

The second branch of CheckWorkDirectory: the directory exists but Directory.GetFiles(directory, "*.csproj") returns no entries. The C# proxy generator needs a .csproj inside the work directory to attach the generated proxy files; absence means the work directory is not a project root.

Solutions

1. Point --work-directory at the folder that directly contains the .csproj (typically *.HttpApi.Client).
2. Verify with 'ls <dir>/*.csproj'.
3. If the project does not exist yet, create it (e.g. add an HttpApi.Client project) before generating proxies.

Example fix

// before
abp generate-proxy -t csharp -wd ./src   // no csproj directly
// after
abp generate-proxy -t csharp -wd ./src/Acme.App.HttpApi.Client

if (!Directory.GetFiles(workDirectory, "*.csproj").Any())
{ Console.Error.WriteLine($"No .csproj in '{workDirectory}'."); return; }

When it happens

Trigger: Pointing --work-directory at a folder that contains source files but no project file (a src/ container, a solution root with only .sln, or a folder of shared code).

Common situations: Passing the solution folder instead of the specific .HttpApi.Client project folder; multi-project folder where the .csproj is one level deeper; project recently deleted/not yet created.
