There is an unfortunate side-effect of writing #Roslyn #Analyzers with respect to compatibility.

The @xunit analyzers target Microsoft.CodeAnalysis 4.2.0 because that's what in VS 2022 17.2, which is currently still in LTS support.

CodeAnalysis 4.2.0 doesn't support C# 12. There are analyzers that are broken because of this, when used with C# 12 language features, and we can't fix them unless we're willing to throw away compatibility with everything before VS 2022 17.8.

I want CA2007 to be smarter.

There's no need to keep re-calling .ConfigureAwait(false) on every single task. The first one is good enough. I've already been shifted off the SyncContext, if there was one.

#Roslyn gripe:

Why doesn't editor.ReplaceNode() take a collection of nodes to use as a replacement? Instead I have to write:

editor.InsertAfter(oldNode, newNodes);
editor.RemoveNode(oldNode);

And then as a bonus, it destroys some of the trivia along the way (like deleting a blank line that it shouldn't delete). (That part may be my fault, I haven't figured out whether I've actually fixed my other bug yet.)

TIL (meaning, Tonight I Learned) that you can declare non-optional parameters after optional ones in C#.

Just create an indexer with optional parameters:

int this[int a, string b = "b"] { get; set; }

The IL for the set method is this:

instance void set_Item (
int32 a,
[opt] string b,
int32 'value'
) cil managed
{
.param [2] = "b"
}

Note that the "value" is after b.

Did you know that you should use TextElementEnumerator to determine the length of a string if the input might have Unicode emojis? Check out the sample below. #dotnet #csharp

I'm curious if future versions of #dotnet should do this check implicitly. 🤔
