Question

似乎与Strange exception coming out of OdbcConnection.Open()有关，但我不确定。

我最近切换到Win8并且之后没有运行此应用程序。我正在使用VS2012，但项目尚未升级。异常的转储如下所示：

Unhandled Exception: System.TypeInitializationException:

App.config看起来像这样：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0"/>
  </startup>
  <runtime>

    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

      <dependentAssembly> <!--For LLBLGen -->
        <assemblyIdentity name="Npgsql" culture="neutral" publicKeyToken="5d8b90d52f46fda7"/>
        <bindingRedirect oldVersion="1.0.0.0" newVersion="2.0.11.0"/>

      </dependentAssembly>
    </assemblyBinding>

  </runtime>
</configuration>

我尝试过重建，但没有用。

尝试在app.config中添加一个空部分。

在ILDASM中查看.exe的清单，我发现了这个，看起来很奇怪：

.assembly zaacmdline
{
  .custom instance void [mscorlib]System.Runtime.Versioning.TargetFrameworkAttribute::.ctor(string) = ( 01 00 00 01 00 54 0E 14 46 72 61 6D 65 77 6F 72   // .....T..Framewor
                                                                                                    6B 44 69 73 70 6C 61 79 4E 61 6D 65 10 2E 4E 45   // kDisplayName..NE
                                                                                                    54 20 46 72 61 6D 65 77 6F 72 6B 20 34 )          // T Framework 4
  .custom instance void [mscorlib]System.Security.SecurityRulesAttribute::.ctor(valuetype [mscorlib]System.Security.SecurityRuleSet) = ( 01 00 01 00 00 ) 
  .permissionset reqmin
         = {[mscorlib]System.Security.Permissions.SecurityPermissionAttribute = {property bool 'SkipVerification' = bool(true)}}
  .hash algorithm 0x00008004
  .ver 0:0:0:0
}

与工作机器相比，TargetFrameworkAttribute肯定是fubar。我该如何解决？

Answer 1

有关查看以下链接的评论应该可以解决问题。 App's .exe file missing .NET TargetFramework, but only on clean builds

基本上：删除C:\Users\YOURNAME\AppData\Local\Temp\.NETFramework,Version=v4.0.AssemblyAttributes.cpp

Answer 2

（来自上述评论）

我的app.config文件中存在大写问题。示例：“connectionstrings”应为“connectionStrings”。这似乎解决了我的问题。

希望这有助于其他人。

Answer 3

只需清除App.Config文件并重建您的项目

App.Config应该像

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
  </startup> 
</configuration>

System.Transactions.Diagnostics.DiagnosticTrace抛出TypeInitializationException
