Hey @yeganehaym, thanks for reaching out. Just to clarify, are you using a Blazor Server app, within a WinForms app, through a WebView? If so, the recommended approach for this is to leverage Blazor Hybrid, which supports WinForms directly, without involving Blazor Server.

If you are in fact running the Blazor Server app within a webview in WinForms, you may be running into permissions issues. Note this is not a supported configuration.

[yeganehaym]

we use webview2 runtime to show desktop window

[TanayParikh]

Are you able to provide a minimal, public, github repository which reproduces this issue?

By:

we use webview2 runtime to show desktop window

Are you suggesting you're navigating to the Blazor Server app in the WebView2 control within the WinForms app? Or are you running a native Blazor Hybrid app using WinForms? You can learn more about Blazor Hybrid here.

something i found out when i run app as admin it happens and dialog doesn't open but when i just dbl click on the exe, open dialog is ok

[TanayParikh]

Ah got it, from the looks of it, you're running a Blazor Hybrid application, and not a Blazor server application within a WinForms webview.

[TanayParikh]

Just tried reproducing your issue in Debug & Release configurations, as well as in a published app. I'm not seeing any issues with opening the input file dialogue.

If you still believe this is a framework issue, we'll need a minimal, public, GitHub repository which reproduces this issue.

this is the structure of my project i got a shared project of blazor server and this shared between winforms and blazor

also you need to run "WinForm App" as admin to see input file not working

[TanayParikh]

i got a shared project of blazor server and this shared between winforms and blazor

So is the *Blazor.Shared project a Blazor Server project, or a Razor Class Library (RCL)?

*.shared project is a class library that is set by

     <PropertyGroup>
        <AddRazorSupportForMvc>true</AddRazorSupportForMvc>

    </PropertyGroup>

and *.blazorServer project and winform proj is referenced to share proj and for windows i use this package

PackageReference Include="Microsoft.AspNetCore.Components.WebView.WindowsForms" Version="6.0.101-preview.11.2349" />

[TanayParikh]

Ah I see, thanks for the details. 6.0.101-preview.11.2349 is from 12/13/2021. Can you please try the latest .NET 7 build or 6.0.547 and confirm if you're still having the issue? If so, we'll need a minimal, public, GitHub repository which reproduces the issue to investigate further.
