当我从其他磁盘共享我的文档时如何安装异步 CTP

发布于 2024-09-30 10:18:14 字数 79 浏览 1 评论 0原文

我尝试安装 Async CTP，它说安装已成功完成，但“我的文档”中没有安装任何内容，并且我找不到示例。可以做什么来查看带有库的示例并尝试它们？

您还有另一台可以安装的机器吗？

我的上网本没有正确接受 CTP 安装，但它确实对 C# 编译器发挥了足够的作用，使该部分正常工作。然后，我从另一台安装成功的机器上复制了 AsyncCtpLibrary.dll，一切都很好。如果您也想复制示例，我相信它们也可以。

如果这是一个常见问题，我建议我们请求许可发布包含示例和库的 zip 文件。

这是一个简短的程序，可让您查看是否已安装 C# 编译器位：

public class Test
{
    static async void Main() {}
}

该程序应该会失败并出现如下错误：

Test.cs(4,22): error CS0656: Missing compiler required member
        'System.Runtime.CompilerServices.VoidAsyncMethodBuilder.Create'
Test.cs(4,22): error CS1993: Cannot find Task-related types. Are you missing a
        reference to 'AsyncCtpLibrary.dll' ?
Test.cs(4,22): warning CS1998: This async method lacks 'await' operators and
        will run synchronously. Consider using the 'await' operator to await
        non-blocking API calls, or 'await TaskEx.Run(...)' to do CPU-bound work
        on a background thread

Do you have another machine you can install on at all?

My netbook didn't accept the CTP installation properly, but it did do enough magic to the C# compiler to make that part work. I then just copied AsyncCtpLibrary.dll from another machine where the installation had worked, and all was fine. If you want to copy the samples as well, I'm sure they'd work too.

If this turns out to be a common problem, I suggest we ask for permission to publish a zip file with the samples and library.

Here's a short program to let you see if you've got the C# compiler bits installed:

public class Test
{
    static async void Main() {}
}

That should fail with an error like this:

Test.cs(4,22): error CS0656: Missing compiler required member
        'System.Runtime.CompilerServices.VoidAsyncMethodBuilder.Create'
Test.cs(4,22): error CS1993: Cannot find Task-related types. Are you missing a
        reference to 'AsyncCtpLibrary.dll' ?
Test.cs(4,22): warning CS1998: This async method lacks 'await' operators and
        will run synchronously. Consider using the 'await' operator to await
        non-blocking API calls, or 'await TaskEx.Run(...)' to do CPU-bound work
        on a background thread
