Question

我有非常简单的代码，它使用nuget Microsoft.CodeAnalysis.CSharp.Scripting：

var script = CSharpScript.Create($@"
IntProp1 = 123;
IntProp2 = 456;
return IntProp1 + IntProp2;
");
var errors = script.Compile();

一个月前，它运行得非常好，突然之间，我开始在这里收到异常消息：

System.TypeLoadException: 'Method 'CommonCreateArrayTypeSymbol' in type 'Microsoft.CodeAnalysis.CSharp.CSharpCompilation' from assembly 'Microsoft.CodeAnalysis.CSharp, Version=3.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation.'

Answer 1

我发现我的nuget依赖版本不匹配：

<PackageReference Include="Microsoft.CodeAnalysis.Common" Version="3.3.1" />
<PackageReference Include="Microsoft.CodeAnalysis.Compilers" Version="3.1.0" />
<PackageReference Include="Microsoft.CodeAnalysis.CSharp.Scripting" Version="3.1.0" />
<PackageReference Include="Microsoft.CodeAnalysis.Scripting" Version="3.1.0" />
<PackageReference Include="Microsoft.CSharp" Version="4.6.0" />

一旦我将“ Microsoft.CodeAnalysis.Common”从“ 3.3.1”更新为“ 3.1.0”，一切就恢复了正常。

Answer 2

在一轮 NuGet 包更新之后，我遇到了与 Razor“编辑并继续”或任何他们所说的类似的问题。已解决：

<PackageReference Include="Microsoft.CodeAnalysis.Common" Version="3.11.0" />

在我的主应用程序/网络项目文件中。

我遇到的错误，特别是：

  An unhandled exception has occurred while executing the request.
  System.TypeLoadException: Method 'get_CommonSyntaxTrees' in type 'Microsoft.CodeAnalysis.CSharp.CSharpCompilation' from assembly 'Microsoft.CodeAnalysis.CSharp, Version=3.8.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation.
     at Microsoft.CodeAnalysis.Razor.CompilationTagHelperFeature.GetDescriptors()

方法'CommonCreateArrayTypeSymbol'没有实现
