Describe the bug

I'm unable to run Blazor - blazorhosted application (as a whole)

I'm unable to compile Blazor.Client side.

Firstly - this error occured

Then:

Exception thrown: 'System.ArgumentException' in System.IO.FileSystem.Watcher.dll
An exception of type 'System.ArgumentException' occurred in System.IO.FileSystem.Watcher.dll but was not handled in user code

System.ArgumentException: 'The directory name 'C:\Repo\Project\Blazor\Blazor.Client\bin\Debug\netstandard2.0\dist\' does not exist.'

After double clicking this error it opens:

Blazor.MonoRuntime.targets

in

C:\Users\Admin.nuget\packages\microsoft.aspnetcore.blazor.build\0.7.0\targets

and points on this line:

<!--` Run the linker and put the results in /obj/<<configuration>>/<<targetframework>>/blazor/blazor/linker -->
    <Exec Command="dotnet &quot;$(MonoLinkerPath)&quot; $(_BlazorLinkerAdditionalOptions) @(_BlazorFolderLookupPaths, ' ') -o &quot;$(BlazorIntermediateLinkerOutputPath)&quot; @(_BlazorAssemblyDescriptorFiles, ' ') @(_BlazorAssembliesToLink, ' ')"  />

To Reproduce

Steps to reproduce the behavior: Probably: 1 Install .NET 2.1.600-preview-009426 2 Install Visual Studio 2019 3 Create dotnet new blazorhosted 4 Try to run the app.

  1. See error

Expected behavior

App starting properly

Additional

I reproduced this bug on 2 different PCs with Win7.

In both cases scenerio was literally the same.
