No response

Steps to Reproduce

I was trying to figure out how to support Transactions for a OWIN application but it seems like when adding the AddAspNet to the code it throws a nullexception error.
The only plausible cause is the HttpContext being null here: https://github.com/getsentry/sentry-dotnet/blob/main/src/Sentry.AspNet/Internal/SystemWebVersionLocator.cs#L20

Expected Result

AddAspNet to not throw a null Exception

Actual Result

There are no line numbers :\

   at Sentry.AspNet.Internal.SystemWebVersionLocator.Resolve(HttpContext context)
   at Sentry.AspNet.SentryAspNetOptionsExtensions.AddAspNet(SentryOptions options, RequestSize maxRequestBodySize)

can u share a repro?

[SimonCropp]

@lucas-zimerman or can you re-run with break on all exception enabled to see what line it occurred on

[SimonCropp]

looking at the code in question

    internal static string? Resolve(HttpContext context)
    {
        if (context.ApplicationInstance?.GetType() is { } type)
        {
            // Usually the type is ASP.global_asax and the BaseType is the Web Application.
            while (type is { Namespace: "ASP" })
            {
                type = type.BaseType;
            }

            if (type?.Assembly is { } assembly)
            {
                return ApplicationVersionLocator.GetCurrent(assembly);
            }
        }

        return null;
    }

the only way i can see a null ref is if HttpContext is null. googling around there seems to be many scenario where HttpContext.Current can be null. given SystemWebVersionLocator.Resolve seems to be "best effort" at finding version. do we add a null check and return null?

@lucas-zimerman - Once this gets released (or if you want to do a custom build now), please let us know if Simon's change in #1881 solved the issue. I'll leave this open until you can check. Thanks.

[lucas-zimerman]

Sure I'll validate it.
EDIT2: Yes it was fixed.
