Question

我正在为我的公司升级遗留应用程序，为了节省时间，我选择重复使用已在一些旧版Crystal Reports中完成的20多个报表，同时使用支持和集成的最新Crystal Reports使用Visual Studio 2015。

新系统中的新报告正在运行，但是一旦我部署到测试服务器，一旦CR运行时升级，所有旧应用程序都无法报告。

这是一种已知行为吗？我没有源/权限来修改CR引用。对于GAC，这不应该是一个问题。

有没有人有过多个版本的Crystal Reports并行运行的经验？

Answer 1

我不得不将报告更改为SQL Server Reporting Services以解决此问题，现在，在项目延迟1.5个月之后，我很高兴我做到了。我们在未来的开发中完全停止使用Crystal Reports，现有的旧应用程序绑定到具有古老CR运行时的旧Web服务器。

Answer 2

您可以使用更高版本的Crystal Reports for VS来构建新应用程序，并在计算机上安装更高版本的运行时，但是使用先前运行时的旧应用程序需要使用.config文件来制作它们工作。

在下面的示例中，您可能有一个使用13.0.2000.0但在PC上安装了运行时间13.0.3500.0的应用程序（将是13 Service Pack 25），然后使文件名与您的应用程序，并在名称后放置.config。

例如，具有可执行文件CutomApplication.exe

的应用程序

CutomApplication.exe.Config（包含下面的文本）
