'"WriteLinesToFile" task was not given a value for the required parameter "File"
Error MSB4044 The "WriteLinesToFile" task was not given a value for the required parameter "File". BlazorTutorial.Client C:\Program Files\dotnet\sdk\5.0.400\Sdks\Microsoft.NET.Sdk.BlazorWebAssembly\targets\Microsoft.NET.Sdk.BlazorWebAssembly.ServiceWorkerAssetsManifest.targets
// !---Line that gives error
<WriteLinesToFile
File="%(_ServiceWorkerIntermediateFile.Identity)"
Lines="/* Manifest version: $(_ServiceWorkerAssetsManifestVersion) */"
Condition="'$(_ServiceWorkerAssetsManifestVersion)' != ''" />
I don't how to resolve this or don't know what other information have to share here. I looked over internet but couldn't find any information about this error.
Things i tried :
- I tried update sdk version 5.0.3 to 5.0.4 but not worked.
- Meaningless but updated visual studio.
- I reverted project to working version from git still getting same error.
- I tried open new project and there was no error.
Edit 1:
- (@Nicola Biada thank you) Cleared project > exited visual studio > deleted bin and obj folders > opened project > rebuilded project > same error accurred
Solved but don't know why:*
// from server's program.cs
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseContentRoot(Directory.GetCurrentDirectory()); // Deleted this line
webBuilder.UseWebRoot("wwwroot"); // And this
webBuilder.UseStartup<Startup>();
});
After that, deleted wwwroot folder at server side and magic become real error gone for good.
