Ich kann nicht scheinen, dieses Problem überall zu finden, wahrscheinlich, weil es so generisch ist.Konnte Datei oder Assembly 'AMS' oder eines seiner Abhängigkeiten nicht laden
Ich habe eine leere asp.net Web-Anwendung in Visual Studio 2017 Community Edition erstellt. Die Anwendung heißt AMS.
Wenn ich debuggen, erhalte ich folgende Fehlermeldung:
Could not load file or assembly 'AMS' or one of its dependencies. The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020)
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.IO.FileLoadException: Could not load file or assembly 'AMS' or one of its dependencies. The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020)
Source Error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
Assembly Load Trace: The following information can be helpful to determine why the assembly 'AMS' could not be loaded.
=== Pre-bind state information ===
LOG: DisplayName = AMS
(Partial)
WRN: Partial binding information was supplied for an assembly:
WRN: Assembly Name: AMS | Domain ID: 2
WRN: A partial bind occurs when only part of the assembly display name is provided.
WRN: This might result in the binder loading an incorrect assembly.
WRN: It is recommended to provide a fully specified textual identity for the assembly,
WRN: that consists of the simple name, version, culture, and public key token.
WRN: See whitepaper http://go.microsoft.com/fwlink/?LinkId=109270 for more information and common solutions to this issue.

Die App ist sehr einfach, so weit. Ich habe Pakete von NuGet für Identiy, EntityFramework, Owin, Owin.Host.SystemWeb, Owin.Security und Owin.Security.Cookies bekommen. Ich habe eine einzelne leere JavaScript-Datei, eine einzelne kurze CSS-Datei und Login und registrieren Aspx-Seite mit einer einzigen MasterPage-Datei mit Links zu der CSS-Datei und Google Content Delivery Network einer JQuery-Datei im Kopfbereich gebunden. Ich habe auch eine Startup.vb erstellt, die die OwinStartup-Assembly lädt und die App so konfiguriert, dass sie die Cookie-Authentifizierung verwendet.
Meine web.config-Datei sieht wie folgt aus:

habe ich versucht, so viele Dinge: Neustarten, Visual Studio 2017 neu zu installieren, um das Projekt von Grund auf neu erstellen wieder und Kopieren/Einfügen der Inhalte in Administrator ausgeführt wird , Reinigen, Neuaufbau, Ändern der Ziel-CPU. Der komische Teil ist, dass es manchmal funktioniert, wenn ich die Seite einige Male aktualisiere oder wenn ich das Debuggen einige Male neu starte, aber manchmal kann ich es nie zum Laufen bringen. Und ich kann anscheinend nichts von der Log/Stack-Spur machen.
Ich sollte beachten, dass ich VS2010 Pro, VS2012 Pro und VS2015 Community auch auf meinem Computer installiert habe.
Wenn es hilft, mein PC ist ein AMDx64, Windows 7.
Vielen Dank im Voraus!
UPDATE: 
haben Sie "Antivirus-Software" auf dem Computer installiert? – Rainmaker
Ja, aber ich hatte es schon immer. Ich habe vor ein paar Monaten ein Web-API-Projekt in VS2015 erstellt und hatte keine der gleichen Probleme. Seither hat sich an meinem Ende nichts geändert, außer dass der neue VS2017 installiert wurde. (Ich habe auch versucht, die App von Grund auf in VS2012 und VS2015 zu erstellen und die gleichen intermittierenden Fehler). – user1422348
