Identityserver4: Receiving error: Method 'FindIdentityResourcesByScopeNameAsync' does not have an implementation

[not-good-with-usernames]

I'm attempting to execute the following:

            var builder = services.AddIdentityServer(
                    options => { options.IssuerUri = "https://boo.com"; })
                .AddExtensionGrantValidator<LPDelegationGrantValidator>()
                .AddProfileService<ONBProfileService>()

                .AddOperationalStore(options =>
                {
                    options.ConfigureDbContext = b =>
                    {
                        b.UseSqlServer(connectionString, db => db.MigrationsAssembly(migrationsAssembly));
                    };
                })
                .AddConfigurationStore(options =>
                {
                    options.ConfigureDbContext = b =>
                    {
                        b.UseSqlServer(connectionString, db => db.MigrationsAssembly(migrationsAssembly));
                    };
                });

This used to work but then I moved the solution to a different location and renamed some of my projects. Now it's crashing with the the following error.

I've tried aligning the versions of the packages I'm referencing to v3.1.3 but it's not fixing this.

Have you seen this error before? Is there a straight-forward way to resolve it?

Hello, I had this error because I had IdentityServer4 beta 4 installed, while the other packages where 3.1.3. After installing IdentityServer4 3.1.3, this error was gone.

Thanks @1Jesper1, after much banging my head on the wall I eventually came to that conclusion too. For some reason some of the packages were defaulting to the preview versions and that was screwing me up.
