有时AutoGenerateBindingRedirects是不够的(即使有GenerateBindingRedirectsOutputType)。搜索所有There was a conflict条目并逐个手动修复它们可能很乏味，所以我写了一小段代码来解析日志输出并为您生成它们(转储到stdout):

// Paste all "there was a conflict" lines from the msbuild diagnostics log to the file below
const string conflictFile = @"C:\AssemblyConflicts.txt";

var sb = new StringBuilder();
var conflictLines = await File.ReadAllLinesAsync(conflictFile);
foreach (var line in conflictLines.Where(l => !String.IsNullOrWhiteSpace(l)))
{
    Console.WriteLine("Processing line: {0}", line);

    var lineComponents = line.Split('"');
    if (lineComponents.Length < 2) 
        throw new FormatException("Unexpected conflict line component count");

    var assemblySegment = lineComponents[1];
    Console.WriteLine("Processing assembly segment: {0}", assemblySegment);
    var assemblyComponents = assemblySegment
                              .Split(",")
                              .Select(kv => kv.Trim())
                              .Select(kv => kv.Split("=")
                              .Last())
                              .ToArray();

    if (assemblyComponents.Length != 4) 
        throw new FormatException("Unexpected conflict segment component count");

    var assembly = assemblyComponents[0];
    var version = assemblyComponents[1];
    var culture = assemblyComponents[2];
    var publicKeyToken = assemblyComponents[3];

    Console.WriteLine("Generating assebmly redirect for Assembly={0}, Version={1}, Culture={2}, PublicKeyToken={3}", assembly, version, culture, publicKeyToken);
    sb.AppendLine($"<dependentAssembly><assemblyIdentity name=\"{assembly}\" publicKeyToken=\"{publicKeyToken}\" culture=\"{culture}\" /><bindingRedirect oldVersion=\"0.0.0.0-{version}\" newVersion=\"{version}\" /></dependentAssembly>");
}

Console.WriteLine("Generated assembly redirects:");
Console.WriteLine(sb);

提示:使用MSBuild二进制和结构化日志查看器，并仅为发出警告的项目中的冲突生成绑定重定向(也就是说，仅超过上述代码[AssemblyConflicts.txt]的输入文本文件的冲突行)。

我也犯了同样的错误，无法用其他答案来计算。我发现我们可以“巩固”NuGet包。

右键单击解决方案 单击“管理Nuget包” 合并选项卡并更新到相同的版本。

我发现(至少在Visual Studio 2010中)，您需要将输出详细信息设置为至少详细的，以便能够发现问题。

这可能是我的问题是一个参考，以前是一个GAC参考，但这不再是我的机器重新安装后的情况。
