* `GrpcWebMode`: An enumeration type that specifies whether the gRPC HTTP request `Content-Type` is `application/grpc-web` or `application/grpc-web-text`.
* `GrpcWebMode.GrpcWeb` configures sending content without encoding. Default value.
* `GrpcWebMode.GrpcWebText` configures base64-encoded content. Required for server streaming calls in browsers.
* `HttpVersion`: HTTP protocol `Version` used to set <xref:System.Net.Http.HttpRequestMessage.Version?displayProperty=nameWithType> on the underlying gRPC HTTP request. gRPC-Web doesn't require a specific version and doesn't override the default unless specified.

`GrpcChannelOptions.HttpVersion` and `GrpcChannelOptions.HttpVersionPolicy` can be used to configure the HTTP protocol version.

> [!IMPORTANT]
> Generated gRPC clients have synchronous and asynchronous methods for calling unary methods. For example, `SayHello` is synchronous, and `SayHelloAsync` is asynchronous. Asynchronous methods are always required in Blazor WebAssembly. Calling a synchronous method in a Blazor WebAssembly app causes the app to become unresponsive.
