Describe the bug
Hello,
following this example:
https://learn.microsoft.com/en-us/aspnet/core/blazor/webassembly-lazy-load-assemblies?view=aspnetcore-8.0
I was able to use the assembly lazy load in a Blazor WebAssembly application in net8, now I am trying to implement the same in a Blazor Web Application with rendermode InteractiveWebAssembly
.
The start solution has two project, the application project and the .Client project. I added a RCL library (LazyLibrary)
to the solution, inside the RCL
I added a page component with @rendermode RenderMode.InteractiveWebAssembly
. I added to .Client project a reference to RCL
and I added
<ItemGroup>
<BlazorWebAssemblyLazyLoad Include="LazyLibrary.wasm" />
</ItemGroup>
to application project file, but I can not navigate to the page in the RCL
.
This are the key points I understood:
The classic Blazor WebAssembly project has Router.AdditionalAssemblies
empty when it starts. The Blazor webApp seems always ignore Router.AdditionalAssemblies
but use the new extension method app.MapRazorComponents<App>().AddAdditionalAssemblies(...)
, so to reproduce the same I didnt add the LazyLibrary
to AddAdditionalAssemblies
. In this case, when I run the applicazion and I try to navigate to the page in the RCL
, I get a 404
and OnNavigateAsync
not fire. So I tried to add the LazyLibrary
to AddAdditionalAssemblies
in programs.cs
. In this way, when I navigate to the page in the RCL, the body of the page is rendered, OnNavigateAsync
fire, but I get the error:
If i first navigate to counter(that download the application) and after I navigate to the page in the RCL I get this error
Maybe because the asemblies added (in OnNavigateAsync
) to Router.AdditionalAssemblies
is ignored.
So is it possible implement Assembly lazy load in a Blazor Web project with rendermode InteractiveWebAssembly
?
If it is useful the simply project I am using is at :
