我遇到了一個測試WPF應用程序的錯誤，我正在使用它學習Prism。錯誤日誌在下面，但其要點是，它似乎無法找到Microsoft.Practices.Unity版本3.5.1.0。根據我的理解，這可能意味着兩件事情：要麼找不到Unity的任何版本，要麼發現Unity的版本號錯誤。如何解決「無法加載文件或程序集」Microsoft.Practices.Unity「錯誤？
爲了排除第一個選項（至少我相信這會排除）我再次檢查dll安裝在需要它的項目和bin文件夾中;每個項目和bin文件夾中只有一個Unity副本。它已安裝，但根據屬性描述，它說版本是3.5.0.0。根據對象瀏覽器，它表示該DLL位於名爲「Unity.3.5.1404.0」的文件夾中。請注意，DLL是使用NuGet安裝的，而我安裝的兩組軟件包稱爲「Prism」和「Prism.UnityExtensions」。這是Unity dll的第二個。
有趣的是，我實際上開始了一個新的教程項目，看它是否能解決問題，並從原始項目中複製了一些項目。我能夠第一次編譯和運行它，但是後來我從App.config文件中取出了下面的代碼段，以查看會發生什麼（愚蠢的錯誤...）並開始出現相同的錯誤。這甚至在我將它添加回App.config文件後。請注意，下面的代碼在創建項目時位於App.config文件中;這不是我以後親自添加的內容。
是否有其他地方我應該尋找可能會導致問題的流氓Unity dll？有什麼我需要添加或刪除，使目前的統一DLL的工作？
代碼，其中的錯誤正在發生（上bootstrapper.Run;這是在App.xaml.cs）：
protected override void OnStartup(StartupEventArgs e)
{
base.OnStartup(e);
Bootstrapper bootstrapper = new Bootstrapper();
bootstrapper.Run();
}
代碼：
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

嘿，謝謝你的回覆。我只是嘗試了清潔和重建解決方案，但卻遇到了同樣的情況。我卸載並安裝了幾次軟件包，然後再次嘗試。通過NuGet包添加的代碼，我得到了與我在文章中提到的相同的錯誤，但是隨着它刪除，程序得到進一步並創建一個窗口，但隨後崩潰，出現了我以前處理的錯誤（http：// stackoverflow.com/questions/29537911/how-to-resolve-could-not-load-file-or-assembly-microsoft-practices-prism-er），我永遠不能修復。有點難倒了。 –
遇到完全相同的問題。試了幾件事，包括上面提到的建議。 –
如果你找到一個修復邁克，讓我知道！我的搜索沒有領先在哪裏。 –
