Error on Publish 57

[rhasce]

Hi all hope it is all well.

I get this on Extensions/server/AttributesExt.cs line 488 and Misc/AttributesDefinicion.cs line 32 error below:

Feature `default literal' cannot be used because it is not part of the C# 7.0 language specification Please use language version 7.1 or greater

Hello I think this is messing me up, I tried 4.7.2 and back to the same error, how do I install 4.8 on Windows 10?
When I set to 4.7.2 it compiles but same error, clearly I need .net 4.8 this is a fresh Publish 57 Servuo, fresh Windows install 🙁

Download .NET Framework 4.8 | Free official downloads

Downloads for building and running applications with .NET Framework 4.8 . Get web installer, offline installer, and language pack downloads for .NET Framework.

dotnet.microsoft.com

try this?

i have the same problem, also using the .net framework 4.8 @manwitch share.

Edit the properties for each project in the solution, change the target framework to .NET 4.8
You can do this by right clicking each project in the Solution Explorer panel in Visual Studio and selecting Properties.

With a fresh install of Servuo pub 57 I got the same errors as stated above (Feature 'default literal' is not available in C# 7.0. Please use language version 7.1 or greater.).

Followed the recommendation above and switched so that the projects uses framework 4.8 instead of 4.7.2 (scripts.csproj, Server.csproj, Ultima.csproj, app.config and ServUO.exe.config).

However I still get the same errors.. Voxpire, any idea if that doesn't work?

This thread covers it; Vita-Nex 5.3.0.1 errors pub 57

It compiles, but I get this error. Since it does compile, I am taking it to be no big deal.

Yes, warnings can generally be ignored.
You can fix that warning by adding a null-check;

        private static readonly Delegate[] _EmptyDelegates = new Delegate[0];

        public static Delegate[] GetEventDelegates(this object obj, string eventName)
        {
            var t = obj as Type ?? obj.GetType();

            var f = _CommonFlags;

            if (t.IsSealed && t.IsAbstract)
            {
                f &= ~BindingFlags.Instance;
                f |= BindingFlags.Static;
            }

            var ei = t.GetEvent(eventName, f);

            if (ei == null)
            {
                return _EmptyDelegates;
            }

            var efi = t.GetField(ei.Name, f | BindingFlags.GetField);

            if (efi == null)
            {
                efi = t.GetField("EVENT_" + ei.Name.ToUpper(), f | BindingFlags.GetField);
            }

            if (efi == null)
            {
                return _EmptyDelegates;
            }

            var efv = (Delegate)efi.GetValue(obj is Type ? null : obj);

            return efv?.GetInvocationList() ?? _EmptyDelegates;
        }
