我正在使用Visual Studio 2015更新2。
我正在编写使用html编辑器的扩展。
有时我会遇到错误，说"尝试TextBuffer编辑，而另一个编辑操作正在进行"，这会阻止我写入窗口我如何知道哪个操作锁定了缓冲区？
它或多或少是随机发生的。（至少我找不到任何可靠的方法来复制它。）只是chengeTextBuffer的命令受到影响，所以我可以自由调试。
如果需要，我很乐意提供任何传统信息。
我设法记录了它拖走的异常。由于命令目标链的原因，它相当长，但似乎有什么东西阻止了写入投影缓冲区。（撤销管理器？）

我得到了同样的错误。关闭并重新打开VS是我发现的唯一有效的解决方案。。。
HTH、
