Future cause

This diagnostic is:

• Reserved for a future version of ASP.NET Core.
• Not currently emitted by the Request Delegate Generator. This diagnostic may be emitted in the next version of ASP.NET Core if it detects an endpoint contains a route handler with a parameter that can't be statically analyzed.

<!-- ## Cause This diagnostic is emitted by the Request Delegate Generator when an endpoint contains a route handler with a parameter that cannot be statically analyzed. ### Rule description The Request Delegate Generator runs at compile-time and needs to be able to statically analyze route handlers in an application. This diagnostic is emitted when the ```razor var app = WebApplication.Create(); var version = "v1"; var route = $"/{version}/todos"; app.MapGet("/vl/todos", () => Results.Ok([new Todo(1, "Write tests"), new Todo(2, "Fix tests")])); app.Run(); record Todo(int Id, string Task); ``` ## How to fix violations Declare the route pattern as an inline string literal in the route handler. ```razor var app = WebApplication.Create(); app.MapGet("/v1/todos", () => Results.Ok([new Todo(1, "Write tests"), new Todo(2, "Fix tests")])); app.Run(); record Todo(int Id, string Task); ``` ## When to suppress warnings This warning can be safely suppressed. When suppressed, the framework will fallback to generating the request delegate at runtime. -->
