C# WPF Very slow application launch
提问by Roman Nazarkin
I've wrote a simple .net WPFapplication(contains only 2 small windows), but its launch is too slow - about 10-20 seconds!
我写了一个简单的.net WPF应用程序（只包含 2 个小窗口），但它的启动速度太慢了 - 大约 10-20 秒！
Profiler says:
Profiler 说：
Main->RunInternal(56%)Main->RunInternal->ctor->LoadBaml(32%)
Main->RunInternal(56%)Main->RunInternal->ctor->LoadBaml(32%)
Biggest part of application load time - is body of Main->RunInternalfunction, this isn't my function and i don't know what they makes. Can their execution time somehow be optimized?
应用程序加载时间的最大部分 - 是Main->RunInternal函数体，这不是我的函数，我不知道它们是做什么的。他们的执行时间可以以某种方式优化吗？
Loading Baml markup it takes 32% of all time, but my program have only 3 XAML files and they are containing less than 100 lines of code. Why does this action take so long?
加载 Baml 标记需要 32% 的时间，但我的程序只有 3 个 XAML 文件，它们包含的代码不到 100 行。为什么这个动作需要这么长时间？
Before asking I have read and tried these tricks, but they didn't help me:
在问之前，我已经阅读并尝试了这些技巧，但它们对我没有帮助：
So, how can I speed up the start time of my application?
那么，如何加快应用程序的启动时间？
Thanks.
谢谢。
PS.I've tested this program on two similar computers and the result is a same.
附注。我已经在两台类似的计算机上测试了这个程序，结果是一样的。

Look at the article mentioned in the comments above.
看看上面评论中提到的文章。
I would suppose it is 8, (Authenticode), it depends on what assemblies you are referencing
我想它是 8，（Authenticode），这取决于您引用的程序集

I have the same problem. Google with RunInternal gives me nothing.
我也有同样的问题。带有 RunInternal 的 Google 什么也没给我。
I then tried to backup my previous codes and delete assemblies and files until there was only a window left.
然后我尝试备份我以前的代码并删除程序集和文件，直到只剩下一个窗口。
然后它起作用了——启动时间从 10 秒缩短到 1 秒！This time, the profiler showed only System.Windows.Application.Run()instead of RunInternal
这次，探查器仅显示System.Windows.Application.Run()而不是 RunInternal
It's very strange that for this computer, even after re-importing the bugged(slow) version, it worked correctly! whereas my laptop, which did not go through the fixing above still boots the program for 10+ sec.
很奇怪，对于这台电脑，即使重新导入了有问题的（慢）版本，它也能正常工作！而我的笔记本电脑，没有经过上面的修复，仍然可以启动程序 10 秒以上。

My problem was that the project itself was located on the network drive. So the app has to do a whole round trip to the destination drive located 500 miles away from my location and back, compile everything - so surely it was taking all the time. I looked at other issues but this was the one in my case.
我的问题是项目本身位于网络驱动器上。因此，该应用程序必须往返于距我所在位置 500 英里的目的地驱动器并返回，编译所有内容 - 所以它肯定花费了所有时间。我查看了其他问题，但这是我的案例。
Make sure you project is located locallybefore you try any other things.
在尝试任何其他事情之前，请确保您的项目位于本地。
