title: C# string interpolation-escaping double quotes and curly braces
body: <p>guys, </p>
  
  <p>I'm building a JSON object from an interpolated string, and not getting how escaping works. I have to use double quotes for the API. </p>
  
  <p>This does not interpolate the expressions between the curly braces:</p>
  
  <pre><code>@"{{
                          ""name"":""{taskName}"", 
                          ""products"": [    
                                      {""product"": ""ndvi_image"", ""actions"": [""mapbox"", ""processed""]}, 
                                      {""product"": ""true_color"", ""actions"": [""mapbox"", ""processed""]}
                                    ], 
                          ""recurring"":true,
                          ""query"":    {
                                          ""date_from"": ""{dateFromString}"",
                                          ""date_to"": ""{dateToString}"",
                                          ""aoi"": {polygon}
                                      },
                          ""aoi_coverage_percentage"":90
                          }}";
  </code></pre>
  
  <p>This throws a bunch of errors-apparently, the curly brackets are not being escaped properly:</p>
  
  <pre><code>$"{{
                          ""name"":""{taskName}"", 
                          ""products"": [    
                                      {""product"": ""ndvi_image"", ""actions"": [""mapbox"", ""processed""]}, 
                                      {""product"": ""true_color"", ""actions"": [""mapbox"", ""processed""]}
                                    ], 
                          ""recurring"":true,
                          ""query"":    {
                                          ""date_from"": ""{dateFromString}"",
                                          ""date_to"": ""{dateToString}"",
                                          ""aoi"": {polygon}
                                      },
                          ""aoi_coverage_percentage"":90
                          }}";
  </code></pre>
  
  <p>How should I format it in order to preserve the internal double quotes and outer brackets while allowing for the values inside the single brackets to be interpolated?</p>
