我创建了一个面向 .net framework 4.6.1 的类库（几乎是一个空白画布，只有一个方法来返回一个字符串，仅用于测试目的）。我想把它做成一个 nuget 包。我正在关注这篇文章https://docs.microsoft.com/en-us/nuget/quickstart/create-and-publish-a-package-using-visual-studio-net-framework，但是当我到达“ nuget pack”我收到以下警告：

"WARNING: NU5128: Some target frameworks declared in the dependencies group of the nuspec and the lib/ref folder do not have exact matches in the other location. Consult the list of actions below:
- Add a dependency group for .NETFramework4.6.1 to the nuspec"

我尝试将依赖项组添加到 .nuspec 文件中：

<?xml version="1.0"?> 
<package>
  <metadata>
    <id>$id$</id>
    <version>$version$</version>
    <title>$title$</title>
    <authors>Author</authors>
    <owners>$author$</owners>
    <requireLicenseAcceptance>false</requireLicenseAcceptance>
    <description>H</description>
    <copyright>Copyright 2019</copyright>
    <tags>blah</tags>
    <dependencies>
      <group targetFramework=".NETFramework4.6.1" />
    </dependencies>   
  </metadata> 
</package>

我也试过：

我是多线程和C++的新手,在尝试在我的应用程序中使用保存文件的线程时遇到问题.代码如下:

#include <iostream>
#include <thread>
#include <fstream>
#include <vector>
#include <sstream>

using namespace std;

void writeCSV(vector<vector<double> > & vec, const char* filename) {

    ofstream output(filename);

    for (vector<vector<double> >::const_iterator i = vec.begin(); i != vec.end(); ++i) {
        for (vector<double>::const_iterator j = i->begin(); j != --i->end(); ++j) {
            output << *j << ", ";
        }
        output << *(--i->end()) << "\n";
    }


}

void testFn(int id) {
    std::ostringstream filename;
    vector<vector<double> > v(460, vector<double>(460,0));
    filename << "test" << id << ".csv";
    const char* fileStr …
