 Emma [it/its] | i was trying to figure out why my code parsing a 780 byte file takes 109 KB of allocations, but the built in profiler wasnt giving me anything at all | 17:28:28 |
 6pak | btw rider has dotmemory builtin aswell | 17:29:11 |
| Emma [it/its] |
but the built in profiler wasnt giving me anything at all
| 17:29:40 |
| 6pak | oh I thought you meant dotnet-sos/dotnet-dump etc | 17:29:57 |
| 6pak | but rider literally embeds dotmemory so they should work the same | 17:30:16 |

| Emma [it/its] | yeah my issue is that the rider builtin variant doesnt do anything at all | 01:34:16 |
| Emma [it/its] | the problem is that i cant make a snapshot because the process exits in less than a second | 01:34:46 |

 GGG | Corngood: it seems like the switch to the source-built variant did have some issues | 03:06:16 |
| GGG | I updated my nix config, and the source-built SDKs don't work with the roslyn-ls packaged with the C# VSCode extension | 03:06:46 |
| GGG | Initially I thought it was an issue with the new extension version, but I downgraded and the issue remains.
No source generators work with the following error:

 Corngood | Do you have a minimal repro? | 12:26:53 |
| Corngood | I tried https://github.com/dotnet/roslyn-sdk/tree/main/samples/CSharp/SourceGenerators on dotnetCorePackages.sdk_8_0-source and it worked. | 15:25:37 |

| GGG | dotnet new console
then add this to Program.cs:
static partial class Regexes
{
[GeneratedRegex(@"[\x00-\x1f\\/:\""*?<>\|]|\.+$")]
public static partial Regex NotAllowedInFolderChars { get; }
}
| 18:41:40 |
| GGG | * dotnet new console (using .NET 9 + .NET 8 combined SDK)
then add this to Program.cs:
static partial class Regexes
{
[GeneratedRegex(@"[\x00-\x1f\\/:\""*?<>\|]|\.+$")]
public static partial Regex NotAllowedInFolderChars { get; }
}
| 18:41:49 |
| GGG | * dotnet new console (using .NET 9 + .NET 8 combined SDK, resulting in a net9.0 project)
then add this to Program.cs:
static partial class Regexes
{
[GeneratedRegex(@"[\x00-\x1f\\/:\""*?<>\|]|\.+$")]
public static partial Regex NotAllowedInFolderChars { get; }
}
| 18:42:00 |
| Corngood | Is it not reproducible if you use only the net9 sdk? | 20:49:34 |
