Dotnet run and dotnet build run for a long time

Dotnet run and dotnet build run for a long time

 

It was suddenly found that VS2017.15.4.5 was very slow to open a project, and it took a long time to generate a project,

 

I always thought it was a problem with vs updates, and found that it was the cause of the project.

 

If a folder in the dotnet core project contains a large number of files, such as node_modules, it will affect the running efficiency of dotnet run,

 

Solution: Add the following content under the <PropertyGroup> node in the csproj file:

<DefaultItemExcludes> $ (DefaultItemExcludes); ClientApp \ node_modules \ ** </DefaultItemExcludes> the path ClientApp \ node_modules \ ** contains a directory containing a large number of files.
