Getting application GUID in a .NET Core 6 application-CodePudding

when I programmed in .NET Framework, I used to get the GUID of the Winforms application this way:

static public string AssemblyGuid
    {
        get
        {
            object[] attributes = Assembly.GetEntryAssembly().GetCustomAttributes(typeof(System.Runtime.InteropServices.GuidAttribute), false);
            if (attributes.Length == 0)
            {
                return String.Empty;
            }
            return ((System.Runtime.InteropServices.GuidAttribute)attributes[0]).Value;
        }
    }

And I could even get other values, such as the company, this way:

static public string AssemblyCompany
    {
        get
        {
            object[] attributes = Assembly.GetEntryAssembly().GetCustomAttributes(typeof(AssemblyCompanyAttribute), false);
            if (attributes.Length == 0)
            {
                return "";
            }
            return ((AssemblyCompanyAttribute)attributes[0]).Company;
        }
    }

That in .NET Core does not work, for example, an empty GUID is returned.

How can I do it?

I just created a Winform project using Net 7 and ran your code it didn't return GuidAttribute your code is looking for. The solution is to add an AssemblyInfo to your project for example:

using System.Runtime.InteropServices;

// In SDK-style projects such as this one, several assembly attributes that were historically
// defined in this file are now automatically added during build and populated with
// values defined in project properties. For details of which attributes are included
// and how to customise this process see: https://aka.ms/assembly-info-properties


// Setting ComVisible to false makes the types in this assembly not visible to COM
// components.  If you need to access a type in this assembly from COM, set the ComVisible
// attribute to true on that type.

[assembly: ComVisible(false)]

// The following GUID is for the ID of the typelib if this project is exposed to COM.

[assembly: Guid("d3870e08-eaf6-4d62-b192-bb2cb42f2fe6")]

The following code will return you the executing assembly id

object[] attributes = Assembly.GetExecutingAssembly()
.GetCustomAttributes(typeof(System.Runtime.InteropServices.GuidAttribute), false);

var assemblyId = ((System.Runtime.InteropServices.GuidAttribute)attributes[0]).Value;

In .netFramework,you could find AssemblyInfo.cs directly:

And modify the settings:

In, .net core,Select Show All Files and search AssemblyInfo.cs

In my case, the attributes you want haven't been attached to the Assembly by default(the two attribute was added by me mannully,not generated automaticlly):

You would access the properties now after adding the two line:

However,We shouldn't modify this file manually.

Then I searched and found this

When it comes to company,you still could set here,or in .csproj file
