swagger 配置错误

1.出现未找到xxx.xml

在csproj里加上

<PropertyGroup>
<GenerateDocumentationFile>true</GenerateDocumentationFile>
<NoWarn>$(NoWarn);1591</NoWarn>
</PropertyGroup>

2.swaggerUI无法显示

app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "Web App V1");
c.RoutePrefix = string.Empty;//设置根节点访问 删掉这句
});
