Could not find 'BlazorExtensions' in 'window' (Server mode)

[carlos-perez-rp]

In a new project, using server side template, I added the reference to BlazorExtensions storage (0.2.1), added the services.AddStorage() line to register the services. If I modify the counter example to this:

`@page "/counter"
@using Blazor.Extensions.Storage
@Inject SessionStorage sessionStorage
@Inject LocalStorage localStorage

Counter

Current count: @currentCount

<button class="btn btn-primary" @OnClick="IncrementCount">Click me

@code {
int currentCount = 0;

async void IncrementCount()
{
    currentCount=await localStorage.GetItem<int>("counter");
    currentCount++;
    localStorage.SetItem("counter", currentCount).Wait();
}

}
`
I receive the error Could not find 'BlazorExtensions' in 'window'.
blazor.server.js is present in Sources when I enter in dev mode in chrome.
dotnet --version outputs 3.0.100-preview7-012821.

Is that correct?

If i compile the .ts scripts, put in wwwroot and init the script directly in _host.cshtml it works, so I think is related to #24

Same issue here. I'm on preview 8.

[galvesribeiro]

Can you please try with the latest packages?

[Hinne123]

@galvesribeiro with the 1.1.0-preview1 it stays the same error message as dtitovgis posted before.

[rovercoder]

Add this to your index.html or _Host.cshtml whichever you are using:

<script type="text/javascript" src="_content/Blazor.Extensions.Storage.JS"></script>

Should the blazor.extensions.storage.js file not get automatically generated clone this github repo and build the solution. You should then find the compiled js there inside the dist folder, then just copy it over to your project in /bin/Debug/netstandardx.x/dist/_content/

[arivera12]

I downloaded the files and tried to compile them and a error is being thrown.
[typescript] Element implicitly has an 'any' type because type 'Window' has no index signature.

[arivera12]

Does someone compiled this successfully?

[rovercoder]

Compiled JS for 1.1.0-preview3: blazor.extensions.storage.js.zip

[arivera12]

@rovercoder everything it's working again! Is this gonna get fixed later?

[rovercoder]

hope so!

[danielmeza]

I had the same problen with the SignalR package using the 3.1.0-preview4.19579.2 of Blazor and the 1.1.0-preview3 of SIgnalR

[bobted]

I've tried using the js file that @rovercoder linked but it didn't help so I've been looking for other discussions about this problem. It looks like BlazorExtensions/SignalR#66 matches and also includes a fork with a potential workaround. The workaround includes adding app.UseStaticFiles(); to a server project's Startup.cs. I have not tried it yet but the thread makes it sound like it works.
