Repro Add PublishSingleFile to csproj

    public async Task<AuthenticationResult> GetAsync(string[] scopes)
    {
        var publicClient = await CreatePublicClient({someappId});
        var accounts = await publicClient.GetAccountsAsync();
        if (accounts.Any())
        {
            // Assume first account
            var account = accounts.First();
            var silentAuthResult = await publicClient
                .AcquireTokenSilent(scopes, account)
                .ExecuteAsync();
            return silentAuthResult;
        }
        return null;
    }

    private static readonly BrokerOptions BrokerOptions = new(OperatingSystems.Windows);

    private static async Task<IPublicClientApplication> CreatePublicClient(string clientId)
    {
        var publicClient = PublicClientApplicationBuilder
            .Create(clientId)
            .WithBroker(BrokerOptions)
            .WithAuthority(AadAuthorityAudience.AzureAdMultipleOrgs)
            .WithRedirectUri(redirectUri)
            .Build();

        // Configure Cross-Execution Token Cache
        var storageProperties = new StorageCreationPropertiesBuilder("msal_cache.txt", MsalCacheHelper.UserRootDirectory)
            .Build();
        var cacheHelper = await MsalCacheHelper
            .CreateAsync(storageProperties);
        cacheHelper
            .RegisterCache(publicClient.UserTokenCache);

        return publicClient;
    }

Expected behavior Code is able to acquire a token silently

Actual behavior

Adding <IncludeAllContentForSelfExtract>true</IncludeAllContentForSelfExtract> to my csproj fixed the issue 😃

[trwalke]

@zachcwillson Have you tried <IncludeAllContentForSelfExtract>true</IncludeAllContentForSelfExtract> as a workaround?
