我相信这是一个权限问题，但我不知道如何解决它，我收到以下异常：

System.IO.FileLoadException: LoadFrom(), LoadFile(), Load(byte[]) and LoadModule() have been disabled by the host.
at System.Reflection.RuntimeAssembly.nLoadImage(Byte[] rawAssembly, Byte[] rawSymbolStore, Evidence evidence, StackCrawlMark& stackMark, Boolean fIntrospection, SecurityContextSource securityContextSource)
at System.Reflection.Assembly.Load(Byte[] rawAssembly, Byte[] rawSymbolStore, Evidence securityEvidence)
at Microsoft.CSharp.CSharpCodeGenerator.FromFileBatch(CompilerParameters options, String[] fileNames)
at Microsoft.CSharp.CSharpCodeGenerator.FromDomBatch(CompilerParameters options, CodeCompileUnit[] ea)
at Microsoft.CSharp.CSharpCodeGenerator.System.CodeDom.Compiler.ICodeCompiler.CompileAssemblyFromDomBatch(CompilerParameters options, CodeCompileUnit[] ea)
at System.CodeDom.Compiler.CodeDomProvider.CompileAssemblyFromDom(CompilerParameters options, CodeCompileUnit[] compilationUnits)

执行以下代码时：

var engine = this.CreateRazorEngine();
var typeName = "view_" + Guid.NewGuid().ToString("N");
var results = engine.GenerateCode(new StringReader(content), typeName, "", typeName + ".cs");
if (!results.Success) { this.Fail("Unable to compile view '" + this.filename + "'."); return; }
using (var codeProvider = new CSharpCodeProvider()) {
    var tempPath = Path.GetTempPath();
    var outputFile = Path.Combine(tempPath, Guid.NewGuid().ToString("N") + ".dll");
    var compilerParameter = new CompilerParameters(this.references, outputFile, true) { GenerateInMemory = true, CompilerOptions = "/optimize", TempFiles = new TempFileCollection(tempPath) };
    var compilerResults = codeProvider.CompileAssemblyFromDom(compilerParameter, results.GeneratedCode);
    if (compilerResults.Errors.HasErrors) {
        var compileExceptionMessage = string.Join(Environment.NewLine + Environment.NewLine, compilerResults.Errors.OfType<CompilerError>().Where(ce => !ce.IsWarning).Select(e => e.FileName + ":" + Environment.NewLine + e.ErrorText).ToArray());
        this.Fail(compileExceptionMessage);
        return;
    }
    this.view = Activator.CreateInstance(compilerResults.CompiledAssembly.GetType(typeName, true, false), true) as ViewBase;                    
}

为清楚起见，CreateRazorEngine 代码为：

private RazorTemplateEngine CreateRazorEngine() {
    var host = new RazorEngineHost(new CSharpRazorCodeLanguage()) { DefaultBaseClass = typeof(ViewBase).FullName };
    foreach(var name in this.usings) { host.NamespaceImports.Add(name); }
    return new RazorTemplateEngine(host);
}

有人可以让我知道什么代码以及我需要把它放在哪里来提高安全级别，以便创建的程序集有足够的权限来加载它已经给出的引用。
