Upgrade. Flurl.Http 2.0 includes the following enhancements to headers:

1. WithHeader(s) now uses TryAddWithoutValidation under the hood. With that change alone, the OP's code will work as originally posted.

2. Headers are now set at the request level, which solves another known issue.

3. When using SetHeaders with object notation, underscores in property names will be converted to hyphens in the header names, since hyphens in headers are very common, underscores are not, and hyphens are not allowed in C# identifiers.

This will be useful in your case:

.WithHeaders(new {
    x_ms_version = "2.11",
    Accept = "application/json"
});
