使用DllImport找不到VSIX dll

Question

我有一個VSIX擴展，它取決於從非託管DLL部署的代碼。我已經將DLL包含在VSIX中，我用zip程序破解了VSIX，以確認它已正確部署。但是，當我使用DllImport屬性時，.NET Framework聲稱它無法找到它。我怎樣才能從我的VSIX打包的DLL中導入函數？

Answer 1

我不知道這裏出了什麼問題，但我重新安裝了Windows和Visual Studio，沒有對該項目進行任何更改，現在一切正常。我還遇到其他一些與其他應用程序查找DLL有關的其他問題，我猜他們是相關的，我必須搞砸了一些設置。

Answer 2

Windows無法打開嵌入到壓縮的.zip中的DLL文件，因此您必須將其解壓縮並放入您有權訪問的文件夾中。

.NET Framework將在%LocalAppData%中查找DLL的路徑，因此在其中解壓DLL是合理的。

Answer 3

我曾經在似乎隨機的情況下得到虛假的包裝負載故障。這些問題主要影響由多個DLL文件組成的擴展。我終於通過將[ProvideBindingPath]屬性應用於擴展中提供的主要Package來解決它們。

您需要在項目中包含該屬性的來源。
