问题补充:

 

去掉这个 才能打开  

MefContainer.GetService<IDbContext>().Preinitialize();

MefContainer.SetContainer(catalog =>
{
var context = HttpContext.Current;
if (context == null)
{
return (CallContext.HostContext ?? (CallContext.HostContext = new MefContext(catalog))) as MefContext;
}
if (context.Items.Contains("MefContext"))
{
return context.Items["MefContext"] as MefContext;
}
else
{
var result = new MefContext(catalog);
if (context != null)
{
context.Items["MefContext"] = result;
context.DisposeOnPipelineCompleted(result);
}
return result;
}
});

 

 

本地正常  上服务器 就报错
