Compilation-time error, no error location output!!! Span<ulong> span = MemoryMarshal.Cast<TestStruct, ulong>(arr);

[delverOne25]

Description

    Span<ulong> span = MemoryMarshal.Cast<TestStruct, ulong>(arr);

Span span = MemoryMarshal.Cast<TestStruct, ulong>(arr);
"error CS0029: Cannot implicitly convert type 'System.ReadOnlySpan' to 'System.Span'

Correct, an explicit conversion is needed:

Span span = MemoryMarshal.Cast<TestStruct, ulong>(arr.AsSpan());
However, Visual Studio doesn't show this error and doesn't detect it at all - compilation just stops abruptly without showing where the error occurred.
