C# 如何将类库项目转换为Web应用程序项目？

1)在靠近顶部的元素之后添加
<ProjectTypeGuids>{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>

2)删除Local

3)在文件的底部,在关闭之前,添加

<Import Project="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v8.0\WebApplications\Microsoft.WebApplication.targets" />
      <ProjectExtensions>
        <VisualStudio>
          <FlavorProperties GUID="{349c5851-65df-11da-9384-00065b846f21}">
            <WebProjectProperties>
              <UseIIS>False</UseIIS>
              <AutoAssignPort>True</AutoAssignPort>
              <DevelopmentServerPort>3291</DevelopmentServerPort>
              <DevelopmentServerVPath>/</DevelopmentServerVPath>
              <IISUrl>
              </IISUrl>
              <NTLMAuthentication>False</NTLMAuthentication>
            </WebProjectProperties>
          </FlavorProperties>
        </VisualStudio>
</ProjectExtensions>
