Question

 private void Context_EndRequest(object sender, EventArgs e)
    {
        var context = ((HttpApplication)sender).Context;
        if (context.Items[typeof(IServiceScope)] is IServiceScope scope)
        {
            scope.Dispose();
        }
    }

When I try to build my project ( Framework 4.7.2 ) I am getting the

: error CS1026: ) expected : error CS1002: ; expected : error CS1513: } expected

On the line

if (context.Items[typeof(IServiceScope)] is IServiceScope scope)

But I don't see where it's throwing the error.

Answer 1

It helped to update "Microsoft.Net.Compilers" over Nuget

now it builds without error.
