c# blazor dependency-injection C#

I'm getting frustrated with I'm relatively new to this, so bear with me... I've been banging my head against this for hours. I'm working with an 'ArgumentException' with the message 'want to provide a value for property 'MyService' on type 'MyComponent'. There is no registered service of type 'IMyService' that matches the constraints of the service.' when trying to inject a scoped service into a Blazor component. I have a service interface `IMyService` and its implementation `MyService`. In my `Startup.cs`, I registered the service as follows: ```csharp public void ConfigureServices(IServiceCollection services) { services.AddScoped<IMyService, MyService>(); services.AddRazorPages(); services.AddServerSideBlazor(); } ``` And then in my Blazor component, I try to inject it like this: ```csharp @page "/mycomponent" @inject IMyService MyService <h3>My Component</h3> <p>@MyService.GetData()</p> ``` I’ve verified that the `IMyService` implementation does not have any issues, and I can see the service is registered properly in the `ConfigureServices` method. However, the exception occurs every time I navigate to this component. I’ve also checked for typos and mismatches in the registration. I suspect it might be related to the scope since I’m also using transient services elsewhere. Could it be that I'm trying to access `MyService` from a context that doesn’t have a proper scope? I would appreciate any insights or suggestions on how to resolve this scenario. For context: I'm using C# on Linux. I'd really appreciate any guidance on this. I'm working on a CLI tool that needs to handle this. Any help would be greatly appreciated! Thanks for your help in advance!
